Capital Budget
13 14
Priorities and Project Drivers
• Hetch Hetchy Power’s capital plan is primarily focused on long- term strategic investment constructing power distribution assets. • Project prioritization and scheduling are tied to customer requirements for energization.
• If investments are delayed or deferred, we may lose prospective customers permanently.
• Most requested capital investments are associated with long- term revenue and increased customer/load base with revenue or cost offsets that are included in the Ten-Year Financial Plan. 15 Ten-Year Capital Plan: Appropriation

SCOPE: Deliver capital improvement projects to sustain the reliability of the nearly 50 mile-long San Joaquin Pipeline (SJPL) System, which conveys water from HHWP's Oakdale Portal to Tesla Valve House.
PROJECT DESCRIPTION: HHWP has developed a program to extend the life of these assets prior to wholesale replacement. It is expected that the program will be able to delay the need for planned large-scale replacement for 20 to 60 years, depending on type of pipe, conditions, valves and operators, instrumentation and control obsolescence, cyber security evolution, environmental factors, and initial installation practices. HHWP's SJPL R&R Program will extend the life of the asset through renewal/replacement, which will constitute betterments to the asset. Typical activities include inspection, condition assessment, design, construction when appropriate, lining and coating replacement, anti-corrosion systems installation, flowmeter and dedicated power upgrades, physical and cyber security, betterments to address regulatory compliance issues, and other life extension activities that meet fixed asset definitions and criteria.
ASSETS: Represented asset families include Oakdale Portal, valve houses, and stand-pipes; SJPL No's. 1, 2, 3 and 4; throttling stations; Emery Crossovers; Roselle Crossovers; Pelican Crossovers; San Joaquin Valve House; Tesla Valve House; corrosion and condition monitoring systems; regulating and control valves; generators, solar panels/inverters/batteries, flowmeters, and other power supplies; instrumentation and controls; all access points; SCADA; and all ancillary equipment.
Justification
The SJPL system was constructed over time between 1931 and 2012, with most assets constructed during 1931 through 1969. Recent and ongoing pipeline condition assessments indicate the potential for decreased reliability and the need for continued renewal and replacement of the pipelines.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Pipeline failures/leaks can interrupt water deliveries. Unanticipated failures can result in increased emergency repair costs, and potentially significant property damage

SCOPE: Provide safe entry into the SJPL System, in compliance with SFPUC Safe Pipeline Isolation procedure, to support future inspection, maintenance and capital improvements of SJPL system.
PROJECT DESCRIPTION: San Joaquin Pipeline (SJPL) Nos. 1, 2, and 3 consist of three parallel transmission pipelines (completed in 1932, 1953, and 1968, respectively) that cross the San Joaquin Valley from the east of Foothill Tunnel at Oakdale Portal to the west of Coast Range Tunnel at Tesla Portal, a distance of approximately 48 miles. A fourth partial pipeline (SJPL 4 completed in 2012) consists of a 6.4-mile segment of pipe downstream of Oakdale and another 11-mile segment upstream of Tesla Portal. SJPLs deliver Tuolumne River water to the San Francisco Bay Area. SFPUC staff members and contractors need to enter the pipelines regularly to perform condition assessment, maintenance, and repair work. A recent hydraulic study shows that several of the existing valves in the SJPLs may be under-rated for the potential surge pressures that could be triggered from an unplanned closure of the valves at the downstream Tesla Ultraviolet Treatment Facility. For safety reasons, the SFPUC initiated this capital project to increase the pressure rating of the valves, provide safe pipeline isolations for personnel entry into the pipelines, and allow shutdown of any section of the SJPLs without a complete system shutdown. The project was broken up into the following phases 1A, 1B, 2A, 2BC, and 3, with all the phases except 2BC substantially completing by May 2025.
ASSETS: Butterfly valves at Tesla Valvehouse (TUV201 through 401), Oakdale Portal, Emery Crossover, Roselle Crossover, and Pelican Crossover and associated actuators; removable spool pieces at each location for each line; knife gate valves at each crossover location.
Justification
This project will improve safe entry into the SJPL System, in compliance with the SFPUC Safe Pipeline Isolation procedure.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
If the proposed work is not implemented, then SJPL cannot be safely isolated and accessed for inspection, maintenance, rehabilitation, and/or replacement without shutting down the entire SJPL System.

SCOPE: Constructed between 1917 and 1925, Mountain Tunnel (MT) is a critical, nonredundant link in the Hetch Hetchy Regional Water System, conveying SFPUC water supply from Kirkwood Powerhouse to Priest Reservoir. Due to the tunnel's 90 years of operation, deferred maintenance, and construction deficiencies from the early 1900s, sections of the tunnel have deteriorated, some more extensively than others. The Mountain Tunnel Inspection and Repairs Project provided a tunnel inspection in 2017 to update the Condition Assessment conducted in 2008. Short-term repairs were also made in 2017 and 2018 to reduce the risk of failures in the concrete lining prior to implementation of the long-term project. The Mountain Tunnel Improvements (Rehabilitation) Project was selected for the design and construction of the preferred engineering alternative that will keep this vital component of the Hetch Hetchy Regional Water System in reliable service for years to come. The budget and schedule are based on the Mountain Tunnel Improvements Project construction phase, which is anticipated to take place between 2021 and 2027. This is the water funded portion of the Mountain Tunnel projects.
PROJECT DESCRIPTION: For the Mountain Tunnel Improvements Project, the water portion will rehabilitate the inside of the tunnel and extend the siphon at South Fork, along with related safety improvements to the roadways that access the Mountain Tunnel.
ASSETS: Mountain Tunnel
Justification
A catastrophic failure is possible with continued tunnel lining degradation. The likely type of anticipated failures are "local collapses," which would not impact power generation but would create water quality events in terms of turbidity in the water supply. The likelihood of localized collapses is moderate to high. Depending on the configuration of the system, this type of event could interrupt the deliveries from the Tuolumne River to the Regional Water System.
Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Depending on the configuration of the system, a "local collapse" could interrupt delivery of Tuolumne River to the SFPUC water customers. Continual degradation of the asset could lead to a catastrophic failure.
Budget Change No Schedule Change No Scope Change Yes
Reason for Change
Scope change accounts for descoping South Fork Siphon Extension, South Fork Road Improvements and Adit 5/6 and 8/9 Road Improvements. The amount descoped from the contract is placed in Directors Reserve and therefore the overall budget has not changed.

SCOPE: Provide remote supervisory monitoring and control over SJPL System, including in-line and cross-over valves.
PROJECT DESCRIPTION: Design, procure, and construct new SJPL remote supervisory controls that would enable remote operation from Moccasin to remotely operate valve actuators. The project includes data telemetry improvements, Remote Terminal Unit (RTU) installation/replacement, trans-valley communication system upgrades, power system upgrades, security improvements, and access improvements.
ASSETS: Represented asset families include Oakdale Portal, valve houses, and stand-pipes; San Joaquin Pipelines Nos. 1, 2, 3, and 4; throttling stations; Emery Crossovers; Roselle Crossovers; Pelican Crossovers; San Joaquin Valve House; Tesla Valve House; regulating and control valves, and actuators; generators and power; instrumentation and controls; and SCADA.
Justification
Pipeline assets were first placed into service in 1931 and vary in age from 10 to more than 90 years old. Three 50 mile-long pipelines cross San Joaquin Valley; a fourth pipeline crosses 17 miles of the valley. All the valves on SJPL are controlled locally, requiring field staff to travel up to 2 hours to reach the valves and operate them. Remote control will allow for valves to be closed remotely, from the Moccasin Control Center, reducing damage in the event of a pipeline failure.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
In the event of pipeline section failure or major leak, field staff must first locate the failure and travel up to 2 hours to close valves to reroute water around the failed pipe section. During this time period, significant water could be released under pressure. Delayed valve closures to isolate major leaks increase third-party and CCSF property damages.

Description
SCOPE: This is a portion of the removed scope of work from the Mountain Tunnel Improvements Project under Contract HH-1000R. This work includes constructing a 100-foot deep by 17-foot diameter shaft at the bottom of the South Fork Access Road, constructing a 750-foot-long bypass tunnel (Siphon Extension) and various roadway and slope improvements so the shaft and siphon extension can be safely constructed. This scope of work was removed from Contract HH-1000R because the contractor refused to do the work. It is recommended that an alternative delivery method is used instead of a Design Bid Build contract to address the required safety and constructability concerns expressed with the HH-1000R contractor.
PROJECT DESCRIPTION: This project is considered an extension of the Mountain Tunnel Improvements Project to complete the work at South Fork.
This work was initially planned to utilize water funding for the South Fork work and it would still be considered a candidate for water funding under a new project.
ASSETS: Mountain Tunnel
Justification
The Flow Control Facility (FCF) control valves that will be installed in the FCF shaft during Outage No. 5 can not be fully utilized until the improvements are made at South Fork. There is a risk over pressurizing the low cover area in the Mountain Tunnel near the existing South Fork Siphon with full utilization of the Flow Control Valves. The new South Fork Siphon Extension would create a new bypass tunnel around the low cover/weak zone of the existing Mountain Tunnel and will allow full operational flexibility for HHWP and not limit the use of control valves and water storage inside the tunnel.
Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
HHWP will need to utilize operational constraint of the control valves until the work at South Fork can be completed. Additional monitoring of the pressures inside the tunnel will need to be performed while using the control valves to make sure the over pressurization of the tunnel does not occur.
Instead of being able to completely fill the tunnel up with water, a limit is being placed as to what station inside the tunnel water can be stored. HHWP operators will need to follow a detailed operating procedure of the control valves and will require 24/7 monitoring of the tunnel.

Prior Approved Finish: Proposed Finish: 03/30/2032
Description
SCOPE: Moccasin laboratory operations, staff, and regulatory requirements have expanded significantly since original construction of Moccasin Water Quality Laboratory. The current laboratory is constructed inside a trailer that is in poor condition and past the end of its service life. Consequently, a new permanent laboratory and office space is needed to meet current operational, safety, and regulatory requirements for testing and processing water samples. The new laboratory building will also provide office space for all personnel currently housed in an adjacent trailer, which is also in poor condition and past its service life.
PROJECT DESCRIPTION: Plan, design, and construct a new water quality laboratory building in Moccasin.
ASSETS: Moccasin Water Quality Building
Justification
The ELAP-certified Moccasin laboratory performs mission-critical microbiological and chemical analyses to support filtration avoidance compliance for the Hetch Hetchy Regional Water System and three HHWP unfiltered small water systems. Additionally, Moccasin Laboratory performs wastewater analyses for HHWP permit compliance and provides “client services” to HHWP for Laboratory Information Management System (LIMS) scheduling, sample collection, and sample receiving. Environmental Laboratory Accreditation Program (ELAP) facility requirements and laboratory instruments have significantly increased over the past 10 years; this has the potential to affect Moccasin laboratory certification if not addressed.
Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability.
Operating Impact
The onsite laboratory provides vital water quality analyses of water delivered to 2.8 million customers.

SCOPE: The project scope is to rehabilitate Moccasin Switchyard.
PROJECT DESCRIPTION: Replace 115 kV disconnect switches, replace 115 kV bus configuration, replace 230 kV disconnect switches, replace 230 kV bus configuration, replace 115 kV circuit breakers, add surge arresters, perform a fault study, perform a grounding study, improve switchyard grading, and replace fencing.
ASSETS: Moccasin Switchyard
Justification
The switchyard was built in 1965. A condition assessment of the switchyard equipment in 2009 indicated much of the equipment has exceeded its life expectancy and requires replacement.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Failure of the Moccasin Switchyard could impact water deliveries from the Tuolumne River to SFPUC customers and could result in potential loss of power generation.
Budget Change Yes Schedule Change Yes Scope Change No
Reason for Change
The variance in budget is due to estimate of construction costs at NAR phase and escalation costs for electrical equipment and labor. The schedule change is based on that during the finalization of the Needs Assessment Report, Hetch Hetchy decided to consider Greenfield as an additional option requiring additional field investigation, survey, potholing, and geotechnical boring.

SCOPE: Deliver capital improvement projects to sustain the reliability of water conveyance assets that are power funded. The R&R Water Conveyance Life Extension (water and joint) and the SJPL Life Extension Project address reliability improvements for other segments of the Hetch Hetchy Regional Water System.
PROJECT DESCRIPTION: HHWP has developed a program to extend the life of these assets prior to wholesale replacement. The program will include inspections, condition assessments, design, environmental evaluations, and construction when appropriate to sustain the reliability of power funded, water conveyance assets with capital improvements. Water is conveyed from upcountry reservoirs to hydroelectric powerhouses via a network of tunnels, pipelines, penstocks, and canals, through valves, gates, portals, penstocks, and reservoir bypasses.
ASSETS: Facilities classified as water conveyance assets include Kirkwood Penstock & valvehouse; Holm Penstock & valvehouse; Cherry Power Tunnel and Cherry Valley Pump Station; Priest Gate Tower; Priest Canal; Moccasin Power Tunnel & surge tower; West Portal valvehouse; Moccasin Penstock; Moccasin Low Head Powerhouse Penstock; Moccasin Low Head Powerhouse tailrace channel; surge tanks; sand traps; valves, valve houses, gates, and actuators; penstock monitoring systems, and related power systems.
Justification
Some of the water conveyance system is well beyond the original service life. Proactive evaluation of water conveyance assets and planned capital investments reduce the water delivery curtailments and interruptions in water delivery.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Loss or reduced capacity of any one of these facilities could impair the ability to deliver water from the Tuolumne River to SFPUC customers. Loss of these systems will also impact power generation from the HHWP Project.

SCOPE: Deliver capital improvement projects to sustain the reliability and safety of Priest Dam. Note: this project is ongoing, but does not currently forecast budgetary needs beyond what has already been allocated. Once the condition assessment is complete, a determination can be made regarding future funding requirements.
PROJECT DESCRIPTION: This project will fund a condition assessment and a stability analysis of the dam using current standards and analysis techniques. New instrumentation will be installed to monitor and document movement of the dam under different storage conditions. The results of these efforts will be used to determine whether a future capital improvement project is required.
ASSETS: Represented asset families include Priest Dam and reservoir; spillway and energy-dissipating components; spillway channels to 100 yards downstream; trash racks and debris removal systems; water outlet conduits, gates, valves, and control systems; dam foundations and abutments; drainage system galleries, pumps, and drain piping; power, lighting, mechanical, and HVAC systems; security and emergency communication systems; access roads and bridges; instrumentation and monitoring systems; and SCADA.
Justification
Priest Dam is an earth and rock-filled dam situated just east of Moccasin on Rattlesnake Creek in Tuolumne County. The dam was built between 1921 and 1923; it is approximately 168 feet tall and 1,000 feet wide, with a crest width of 20 feet. Priest Dam has a long history of issues related to settlement and deflection. Unresolved dam safety deficiencies (e.g., continued settlement) could influence California Division of Safety of Dams to issue dam operating restrictions limiting the operating water surface elevation range, reducing maximum water surface elevation, or increasing dam safety surveillance requirements. Water surface elevation restrictions would impair the regulating benefits of the reservoir.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
The dam not only serves as a regulating forebay for Moccasin Powerhouse but plays an important role in meeting SFPUC water deliveries from the Tuolumne River. In the event of an unplanned outage of facilities upstream of Priest Reservoir, storage in this reservoir can provide sustained SFPUC water deliveries for 2-5 days, providing an opportunity HHWP to address the outage or for the Water Supply and Treatment Division to increase deliveries from the local system.
Storage in Priest Reservoir is also used to sustain SFPUC water deliveries during short, planned maintenance events for assets upstream of Priest Reservoir. California Division of Safety of Dams accepted HHWP's Dam Safety Program requirement for periodic condition assessments. The dam was constructed in 1923 and future capital projects are anticipated.

SCOPE: Provide a reliable hydraulic bypass and energy dissipation system, conveying water around the turbines to Kirkwood Powerhouse Bypass Chamber and Mountain Tunnel.
PROJECT DESCRIPTION: Upgrade/replace high-pressure energy-dissipating valves, control systems, and associated structures to absorb 1,245 feet of pressure head and 430 cubic feet per second flow without damage.
ASSETS: Kirkwood Generator Bypass
Justification
The existing hydraulic bypass and energy-dissipation system cannot be operated for more than about two weeks without incurring significant damage.
When operated, the impact from the high-pressure/high-flow water destroys the energy-dissipating structures in the bypass structure. The bypass chamber was repaired in 2017 and 2019 following short operational periods. Funding for this project is not scheduled until FY 27/28.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
When SFPUC power transmission lines are de-energized, water deliveries to SFPUC customers from the Tuolumne River must be diverted through the Kirkwood Generator Bypass. This project increases HHWP operating flexibility by decoupling water delivery from power production. This enables HHWP to meet scheduled water deliveries by utilizing the Kirkwood Generator Bypass system in the event Kirkwood Powerhouse, Early Intake Switchyard, Intake-Warnerville 230 KV Transmission Lines #5 or #6, or Warnerville-Standiford 115 KV Transmission Lines #7 and #8 are curtailed or de-energized. (Examples of curtailment or de-energization activities affecting these assets include wildfire, transmission outages, or construction.)
Budget Change Yes Schedule Change Yes Scope Change No
Reason for Change
The change in budget is a result of increased construction cost due to escalation. The change in schedule is due to the project being deferred by three years to accommodate higher priority projects and to maintain the baseline budget for the 10-year CIP.

When HHWP power transmission lines are de-energized, water deliveries to SFPUC customers that normally pass through the Moccasin Powerhouse generators must be diverted through the Moccasin generator bypasses. This project increases HHWP operating flexibility by decoupling water delivery from power production. This enables HHWP to meet scheduled water deliveries by using the Moccasin Powerhouse bypasses in the event Moccasin Powerhouse, Moccasin Switchyard, or Moccasin-Newark 115 kV Transmission Lines #3 and #4 are curtailed or de-energized, e.g., wildfire, transmission outage, construction.
Budget Change Yes Schedule Change Yes Scope Change Yes
Reason for Change
Independent Technical Review of the 95% design highlighted hydraulic concerns requiring redesign. Three options were considered for redesigning with Valve House and Dissipation Structure at various locations. Option ”C” was favored by Operations due to the Valve House, Dissipation Structure, and Connection Chamber being all close to Moccasin Reservoir. The Option “C” cost estimate and schedule have been analyzed and evaluated. Current schedule allows for Bid/Award to commence in October 2026 with NTP anticipated in July 2027.

SCOPE: Deliver capital improvement projects to sustain the reliability of HHWP's electric transmission assets from the generator step-up transformer across transmission lines to the terminal substations and switchyards. HHWP has developed a program to extend the life of these assets prior to wholesale replacement.
PROJECT DESCRIPTION: The program will include inspections, condition assessments, design, environmental evaluations, construction when appropriate to sustain the reliability of the electric transmission system, and development of a business plan for transmission rebuild.
ASSETS: Represented asset families include high voltage electric switchyards, substations, and transformer decks; buss structures; circuit breakers; transformers, pull boxes, & foundations; switches & disconnects; relays; capacitors; conductors, optical ground wire, fiberoptic cable, & grounding wires; transmission towers and footings; insulators, dead-ends, and connectors; instrumentation and control systems; and SCADA.
Justification
SFPUC maintains 162 miles of 115 kV and 230 kV electric transmission line miles from HHWP powerhouses to PG&E's Newark Substation in the Bay Area. Most of the towers were erected between 1925 and 1960. A 2009 condition assessment cataloged the structural condition of the towers, electrical conductors, insulators, switches, and relays. Some of the equipment is reaching the end of their planned useful life. HHWP performs reoccurring five-year inspections of structural lattice members and bolts. HHWP is requesting funds to review the condition assessment, develop a business plan for transmission rebuild, develop an Alternatives Analysis Report, and prioritize plan for work to 1) minimize impact to SFPUC water operations; and 2) minimize impact on HHWP water and power operations due to electrical grid transmission construction improvements being performed by other entities. This funding would also cover emergency repairs that cannot wait for systematic and prioritized repair.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Water Delivery Impact: SFPUC deliveries from the Tuolumne River are coupled to the hydroelectric generation at Kirkwood and Moccasin Powerhouses. The powerhouses reduce the line pressure of the Tuolumne River supply to levels compatible with pipeline pressure ratings across San Joaquin Valley. Failures in the electric transmission system cause the powerhouses to shut down, interrupting deliveries from the Tuolumne River to SFPUC customers.
Power Revenue Impact: The SPFUC must develop a long-term business strategy for transmission assets to manage costs and optimize revenues for power generation.

Transmission Lines 7/8 Upgrades
Facility Category: Power Infrastructure
Project Manager: Edward Allen Current Active Phase: Completed Prior Approved Budget: $ 37,327,197 Proposed Budget: $ 32,583,133 Prior Approved Start: 12/02/2019 Proposed Start: 12/02/2019 Prior Approved Finish: 01/31/2025 Proposed Finish: 03/07/2025 Description
SCOPE: HHWP electric transmission Lines 7/8 convey power from Warnerville Substation to Modesto Irrigation District's Standiford Substation. This project will replace existing conductors along Transmission Lines 7 & 8 to mitigate the impacts of new renewable power generation being added to the California electrical grid.
PROJECT DESCRIPTION: This project develops the scope of work, design, and contract documents necessary to bid, award, and manage the reconductoring contract. Reconductoring will include replacement of the existing 115 kV conductors on Lines 7/8 from Warnerville to Standiford substations, resulting in increased capacity and resolving clearance detections.
The project is primarily funded by renewable generation developers interconnecting to the California electrical grid who have an adverse impact on Lines 7/8. Remaining funding came from capital funds previously allocated to the Transmission Line Clearance Mitigation Project (10014089). Project work has been completed and the project is being closed out.
ASSETS: Transmission Lines 7/8
Justification
New renewable generation projects are being connected to the California electrical grid, which is managed by the California Independent System Operator (CAISO). These new generation projects can have an adverse impact on existing transmission facilities, including assets owned and operated by HHWP. HHWP has performed an analysis and determined generation projects associated with CAISO Clusters 7 through 9 have an adverse impact on Lines 7/8. HHWP has developed a mitigation project to reconductor Lines 7/8, beginning at HHWP Warnerville Substation and terminating at Modesto Irrigation District's Standiford Substation. Without modifications, HHWP transmission will have reliability issues, requiring HHWP to reduce generation at Holm and Kirkwood Powerhouses. HHWP has developed a mitigating project that will be partially funded by the Cluster 7 through 9 developers.
Reconductoring with tower modifications also resolves multiple locations where the clearance between the existing conductors and the ground or structures do not meet current safe clearance regulations.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
New renewable generation projects connecting to the California electrical grid will impact the reliability of HHWP Lines 7/8 from Warnerville to Standiford. If the project is not completed, HHWP will be required to reduce generation at Holm and Kirkwood powerhouses to mitigate the impact of the new renewable generation projects after they connect to the California electrical grid.

Facility Category: Power Infrastructure
Project Manager: Jimmy Leong Current Active Phase: Construction Prior Approved Budget: $ 100,556,003 Proposed Budget: $ 126,495,541 Prior Approved Start: 09/18/2020 Proposed Start: 09/18/2020 Prior Approved Finish: 12/31/2028 Proposed Finish: 03/31/2031 Description
SCOPE: The powerhouse was completed in 1969 and generates a combined maximum output of 110 megawatts. Both generator units and transformers have exceeded their life expectancy and need repair to continue operating reliably. Since their original installation, the generators have not had major maintenance work performed (no rewinds or overhauls).
PROJECT DESCRIPTION: The project is broken down into three components: 1) Generator Rehabilitation - replace the entire generator and associated equipment, including new stator cores and coils, rotor poles, relays, and rotor rim; 2) GSU Replacement - replace two of the three existing generator step-up transformers (GSUs), new foundations and oil containment, and relay upgrades; and 3) Power Plant Systems Upgrades - replace the 480 V switchgear, 13.8 kV switchgear, motor control centers, main control boards, protective relays, cooling water piping, and improving oil containment systems.
ASSETS: Moccasin Powerhouse
Justification
The Moccasin Powerhouse is a vital component of the Hetch Hetchy Regional Water System. When Moccasin Powerhouse or generator step up transformers are out of service, water deliveries to SFPUC customers from the Tuolumne River can be impacted. The units have become less reliable and have resulted in 35 outages over a four-year period (2018-2021).
Procurement of failed components may require a procurement period of 18 months or more for long-lead items (e.g., transformer replacement or generator rewind components). Loss of both hydro-generation units, or GSUs, will result in a loss of water deliveries from the Tuolumne River to SFPUC customers for an extended period of time.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Potential loss of reliable water delivery from the Tuolumne River to SFPUC customers and potential loss of power generation.
Budget Change Yes Schedule Change Yes Scope Change Yes
Reason for Change
The variance between the approved budget and forecasted cost is due to increased cost contingency of the DB-121R2 contract for the new fire suppression system and solutions to address Unit M1 alignment, as well as forecasted cost increases in Subproject C – Systems Upgrade, where higher costs are anticipated from scope refinement, higher construction and procurement costs, and additional construction management and support resource requirements. The schedule change is a result of the delay in the Moccasin Bypass Upgrades project. Construction for that project must be completed before physical work inside the powerhouse and outages for Subproject C can begin.

SCOPE: When the Cherry-Eleanor pump system was constructed, it enabled diversion of approximately 110,000 acre-feet of water annually from Lake Eleanor to Cherry Reservoir, resulting in an additional 220 GWh annually (about 13 percent of the annual generation from the project). Pumps in Cherry Reservoir have exceeded their life expectancy. Six out of ten pumps are inoperable and the remaining four pumps are at continued risk of failure. All ten pumps have failed in the past and have been repaired or replaced at various times since being installed.
PROJECT DESCRIPTION: Replace and upgrade pumps in Cherry Pump Station with units that work with current operating strategies. The scope of work includes: 1) replacement of pumps, transformer, and pump motor starters; 2) installation of Programmable Logic Controller (PLC), SCADA system, and fiber optics; and 3) improvement of the existing motor control center (MCC) building.
ASSETS: Cherry Eleanor Pumps
Justification
Cherry Reservoir Pump Station facilitates conveyance of water from Lake Eleanor to Cherry Reservoir via Cherry Diversion Tunnel. Water from Cherry Reservoir enables cost-effective generation of hydropower at Holm Powerhouse. When all pumps are operational, the additional water from Lake Eleanor allows for increased power generation.

SCOPE: HHWP owns assets in areas designated by California Public Utilities Commission as "High Fire Threat Zones." HHWP has evaluated prevention, mitigation, and response strategies to mitigate the threat of wildfire.
PROJECT DESCRIPTION:
This project will fund wildfire mitigation vegetation management projects, including fuel breaks and Integrated Vegetation Management (IVM) projects to protect assets classified as "Power" only. This project does not fund annual vegetation management plans.
Transmission line IVM: (Power)
This project will remove fire prone brush species and any hazard fall-in risk potential trees (including outside the Right of Way) along HHWP Transmission Lines. The Right of Way vegetation will be replanted with low growing native grass and pollinator species. Where applicable, in areas with increased conductor height, the project will re-plant conifer and hardwood trees. Annual maintenance after replanting would include target herbicide applications, brush removal and monitoring of replanted vegetation.
Water Quality IVM: (Power)
Wildfire can impact the water quality of water that could enter Priest Reservoir. The Wildfire Mitigation will include mastication, chain-sawing, and hand-clearing to remove undesirable woody species; dead, diseased, or otherwise hazardous trees; and foliar herbicides including but not limited to Yellow Star Thistle and Himalayan Blackberry. Vegetation along roadways and parking areas will be thinned and scaffold branches lifted to insure adequate access during fire events. The project will include introduction of native vegetation including milkweed, black oak, and ponderosa pines in appropriate areas to promote diversity, pollinator habitat and fire resilience.
Projects will also include creation of other permanent fire breaks to protect power funded assets.
ASSETS: Transmission Lines 1&2, 5&6 and 9,10 &11, Intake Switchyard, Priest Reservoir Justification
The SFPUC's wildfire mitigation projects will vary by asset, location, and terrain. Wildfire is continuing to become more prevalent in California, requiring additional resources to mitigate risks and maintain operations.
Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.
Operating Impact
Wildfire threatens the Hetch Hetchy Project area and neighboring lands. Uncontrolled wildfire presents a safety risk to staff and the public and could potentially limit HHWP's ability to deliver water and, generate power. This project has a positive impact on operations by improving the system's resiliency to wildfire in a sustainable manner as well as reducing the likelihood of ignition.

SCOPE: Deliver capital improvement projects to sustain the reliability of Priest Dam.
PROJECT DESCRIPTION: HHWP has developed a program to extend the life of this asset prior to replacement. The program includes inspections, condition assessments, design, environmental evaluations, and construction when appropriate.
ASSETS: Represented asset families include Priest Dam and reservoir; spillways and energy-dissipating components; spillway channels to 100 yards downstream; trash racks and debris removal systems; water outlet conduits, gates, valves, and control systems; dam foundations and abutments; drainage system galleries, pumps, and drain piping; power, lighting, mechanical, and HVAC systems; security and emergency communication systems; access roads and bridges; instrumentation and monitoring systems; and SCADA.
Justification
Priest Dam not only serves as a regulating forebay for Moccasin Powerhouse but plays an important role in meeting SFPUC water deliveries. In the event of an unplanned outage of facilities upstream of this facility, storage in Priest Reservoir can provide sustained SFPUC water deliveries for 2-5 days, providing an opportunity HHWP to address the outage or for WST to increase deliveries from the local system. Storage in Priest Reservoir is also used to sustain SFPUC water deliveries during short, planned maintenance events for assets upstream of Priest Reservoir. California Division of Safety of Dams accepted HHWP's Dam Safety Program requirement for periodic condition assessments. The dam was constructed in 1923 and future capital projects are anticipated.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Unresolved dam safety deficiencies could influence California Division of Safety of Dams to issue dam operating restrictions, limiting the operating water surface elevation range, reducing the maximum water surface elevation, or increasing dam safety surveillance requirements. Water surface elevation restrictions would impair water and power benefits of the reservoir.

Description
SCOPE: New generation in Fresno/Kern counties connecting to the electrical grid is having an adverse impact on HHWP facilities Warnerville Substation and Lines 7/8. To mitigate these adverse impacts, this project adds an additional autotransformer at Warnerville Substation, ties Lines 3/4 into Warnerville Substation, and constructs a new 115 kV transmission line between Warnerville Substation and TID’s Oakdale Substation.
PROJECT DESCRIPTION: This project develops the scope of work, design, and contract documents necessary to bid, award, and manage the addition of a new transformer to Warnerville Substation, as well as the addition of the connection of Lines 3/4 into Warnerville Substation and a new 115 kV transmission line between Warnerville Substation and TID’s Oakdale Substation. For the transformer, the project includes 115 kV and 230 kV electrical (e.g., circuit breakers, switches, metering equipment, grounding, protection) and structural equipment (e.g., foundation, buss structure) to accommodate an additional 230 kV autotransformer. For the new transmission line, the project includes civil improvements (e.g., additional right-of way, improvements), and 115 kV electrical (e.g., circuit breakers, switches, metering equipment, grounding, protection) and structural equipment (e.g., foundation, pull off tower, buss structure) to accommodate the interconnection of Lines 3/4 and for the construction of the new transmission line.
The project will be funded by renewable generation developers interconnecting to the California electrical grid who have an adverse impact on Warnerville Substation and Lines 7/8.
ASSETS: Warnerville Substation.
Justification
New renewable generation projects are being connected to the California electrical grid, which is managed by the California Independent System Operator (CAISO). These new generation projects can have an adverse impact on existing transmission facilities, including assets owned and operated by HHWP. HHWP has performed an analysis and determined generation projects associated with CAISO Clusters 14 have an adverse impact on Warnerville Substation and Lines 7/8. HHWP has developed a mitigation project to add new autotransformer to Warnerville Substation, and a second project to connect Lines 3/4 into Warnerville Substation and add a new 115 kV transmission line between Warnerville and TID’s Oakdale Substation.
Without these modifications, HHWP transmission will have reliability issues, requiring HHWP to reduce generation from Holm and Kirkwood Powerhouses. HHWP has developed a mitigating project that will be funded by the Cluster 14 developers.
Water Level of Service Goal(s) Supported: Power Delivery, Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
New renewable generation projects connecting to the California electrical grid will impact the reliability of HHWP Warnerville Substation and Lines 7/8 from Warnerville to Standiford. If the project is not completed, HHWP will be required to reduce generation at Holm and Kirkwood powerhouses to mitigate the impact of the new renewable generation projects after they connect to the California electrical grid.

Description
SCOPE: Renewable energy developer Engie desires to construct a 500-megawatt clean energy battery storage facility, substation and switchyard on approximately 25 to 30 acres of City property in Sunol. The Engie entity project owner is Alameda Reliability Project LLC (Entity). The facility would interconnect to PG&E through the Newark-Tesla 230 kV line. The City, through the SFPUC, would issue a long-term lease to the Entity for the use of the battery storage and substation facility on City property. PG&E will own the equipment in the switchyard. In addition, the Entity will build a New Calaveras Substation increasing the capacity to serve Sunol Valley Water Treatment Plan facilities from 6.75 to 15 megavolt-amperes with redundancy.
The Entity will transfer the New Calaveras Substation to the SFPUC following completion of the project (HHWP asset). SFPUC will also be responsible for negotiating the new interconnection to the New Calaveras Substation with PG&E and reviewing/approving the design of the New Calaveras Substation.
PROJECT DESCRIPTION: This project supports coordination activities to build the Alameda Reliability Project on SFPUC property including a New Calaveras Substation that will be owned by the SFPUC. The New Calaveras Substation will be built in the vicinity of the existing substation. The new substation will include 22 kV and 230kV electrical equipment (e.g., circuit breakers, switches, metering equipment, grounding, protection) and structural equipment (e.g., foundation, buss structure) to accommodate two 230 kV to 22 kV autotransformers. The substation will connect to the Water Supply and Treatment Division's existing distribution lines on the low-side and PG&E’s Newark-Tesla 230 kV line on the high-side.
ASSETS: Calaveras Substation.
Justification
Alameda Reliability Project LLC (Entity) proposes to construct a 500-megawatt clean energy battery storage facility, substation and switchyard on approximately 25 to 30 acres of City property in Sunol. This project will have multiple synergies with SPFUC objectives:
- New Calaveras Substation will serve SVWTP facilities via the PG&E 230 kV transmission line, freeing up the SFPUC Lines 3/4 right-of-way from Calaveras Substation to PG&E’s Newark Substation for the potential SFPUC-California Independent System Operator Warnerville-Newark Transmission Expansion Project (WaNTEP);
- The Entity will build a new Calaveras Substation that will be transferred to the SFPUC. The capacity of the new substation will be increased from 6.75 to 15 megavolt-amperes and provide additional redundancy for maintenance/outages; - Project has “full deliverability” within Bay Area Local Resource Adequacy Area, and could provide a needed 25 megawatts of Resource Adequacy for HHWP power customers; and
- The Entity may be able to provide additional battery storage that could serve SVWTP facilities during PG&E 230 kV outages.
For these reasons we conclude that the Entities proposal on SFPUC watershed land is consistent with SFPUC plans and policies, and will provide substantial benefits to the SFPUC. Given these benefits and that the project meets the provisions of the AWMP, this project should be recommended for approval. In addition, SFPUC will have a revenue stream to be negotiated from the lease for at least 20 years.
Operating Impact
The SFPUC and California Independent System Operator are considering the Warnerville-Newark Transmission Expansion Project (WaNTEP) which will be built on the transmission Lines 3/4 right-of-way. To build this new asset, Sunol Valley Water Treatment Plant facility loads can no longer be served power from existing Lines 3/4. In addition, Sunol Valley Water Treatment Plant facility loads are increasing, and Calaveras Substation is reaching capacity. In addition, there is no redundancy at Calaveras Substation and testing/maintenance activities often require Calaveras Substation to be de-energized requiring Sunol Valley Water Treatment facilities to go on back-up power. This project will address these issues.

Description
SCOPE: SFPUC proposed a project in the California Independent System Operator (CAISO) 2024-2025 Transmission Planning Process (TPP) Request Window that would utilize the SFPUC's existing 100-mile Moccasin-Warnerville-Newark 115 kilovolt (kV) lines (3 & 4) Right-of-Way (RoW). The proposed project would rebuild either a new approximately 70-mile High Voltage Direct Current (HVDC) line or a 230 kV Alternating Current (AC) line between the Warnerville and Newark substations. The name of the project is the Warnerville-Newark Transmission Expansion Project or WaNTEP.
CAISO is considering the WaNTEP as a reliability alternative in the 2025-2026 TPP cycle. Preliminary findings demonstrate that WaNTEP AC or HVDC configurations are highly effective in addressing North American Electric Reliability Corporation and CAISO transmission planning criteria violations/overloads on several greater Bay Area transmission facilities.
PROJECT DESCRIPTION: This project supports coordination activities to build WaNTEP, which may involve either a 230 kV AC transmission line, a 1,000 MW HVDC, or a 230 kV AC transmission line. If selected, the 230 kV AC transmission line will include towers and conductor. If selected, the 1,000 MW HVDC will include towers, conductors, and two converter stations —one at Warnerville and the other at Newark. The Needs Assessment and Alternative Analysis Report are being developed by the CAISO and reviewed by the SFPUC. If approved, construction for the project will be negotiated with the CAISO. This project will generate a revenue stream for the SFPUC.
ASSETS: Lines 3 & 4 rebuild from Warnerville to Newark
Justification
This project will meet the SFPUC’s need to replace an end-of-life asset and help meet the reliability and policy needs of the State of California. This project provides for the full replacement of SFPUC power transmission Lines 3 & 4, which are over 100 years old. In addition, energy demands are increasing rapidly in the greater Bay Area, potentially causing overloads on existing transmission lines within the CAISO-controlled grid. The increased capacity provided by SFPUC’s proposed WaNTEP addresses future overloads on many 230kV import lines into the greater Bay Area, as identified in the CAISO’s 2025-2026 Transmission Planning Process (TPP). This will provide reliability benefits to San Francisco and the greater Bay Area. The SFPUC expects to recover all the costs of building and maintaining WaNTEP from the CAISO-wide transmission access charges, while earning a return on its investment.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Lines 3 & 4 are over 100 years old and exceed their life expectancy, increasing risk of infrastructure failure and power outages. About 17 percent of Lines 3 & 4, which will be replaced through WaNTEP, are within High Fire Threat District 2. We have processes in place to minimize wildfire risk, but the potential for risk remains.

SCOPE: Early Intake Dam is in an advanced stage of deterioration, with severe cracking of the concrete structure as a result of internal expansion from concrete alkali aggregate reaction. Past engineering studies concluded that permanent repair of the alkali aggregate reaction concrete is not feasible, and the dam should be replaced. Recent studies in 2020 and 2021 revealed additional structural stability concerns and concluded that interim remediation measures are not feasible.
PROJECT DESCRIPTION: Remove the existing deteriorated dam and construct a new concrete diversion structure and conveyance system within the existing Raker Act boundary to divert flows from Cherry Creek and Tuolumne River upstream of Kirkwood Powerhouse into Mountain Tunnel for SFPUC customers during emergencies.
ASSETS: Early Intake Dam
Justification
This project is needed to ensure dam safety and long-term reliable water delivery. Without Early Intake Dam, HHWP would not have a way to divert water from Lower Cherry Aqueduct and Tuolumne River upstream of Kirkwood Powerhouse into Mountain Tunnel during drought or emergency conditions.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability.
Operating Impact
Under normal operations, the SFPUC Tuolumne River water supply flows from O'Shaughnessy via O'Shaughnessy Diversion Works to Canyon Tunnel, then through Kirkwood Penstock and Kirkwood Powerhouse, then through Intake Bypass Tunnel to Mountain Tunnel. In the event of drought or failure of O'Shaughnessy Diversion Works, Canyon Tunnel, Kirkwood Penstock, or Intake Bypass, Early Intake Dam is required to direct water from the Tuolumne River, or from Lower Cherry Aqueduct, into Mountain Tunnel. This project provides a critical alternative mean to divert water from the Tuolumne Watershed into Mountain Tunnel for deliveries to SFPUC customers under drought and/or emergency conditions when Kirkwood Powerhouse and bypass are not operable.
Budget Change Yes Schedule Change Yes Scope Change Yes
Reason for Change
The original schedule and estimate were based on an order of magnitude estimate. Updated engineering study of conceptual alternatives with more detailed evaluation found that more extensive scope and environmental permitting efforts are needed to remove and replace the dam.
As of April 2025, this project is being placed on hold until further investigation is performed by SFPUC and will be restarted as a new candidate project.

SCOPE: HHWP is responsible for maintenance and upgrades to approximately 80 buildings, structures, facilities, and systems, many of which have exceeded their service lives. Facilities provide office space; warehousing of materials, supplies, and critical spare equipment; maintenance and vehicle shops; fire suppression systems; HVAC; water treatment, storage, and distribution facilities; wastewater collection, treatment, and discharge facilities; stormwater collection and discharge facilities; and cottages for essential onsite workers and NPS/USFS staff. This program delivers capital improvement projects to sustain serviceability for facilities used to meet Hetch Hetchy Regional Water System objectives.
PROJECT DESCRIPTION: The program includes inspections, condition assessments, design, environmental evaluations, and construction, when appropriate. Typical projects include roof and waterproofing replacements; security, fire detections/suppression, and HVAC upgrades; building remodels to meet current business/operational needs; replacement of rotted/deteriorated structures; replacement of deteriorated underground pipelines and conduits; and upgrades to water and wastewater treatment plants to meet current regulatory standards.
ASSETS: Represented asset families include the types of facilities described above at Cherry Compound, O'Shaughnessy Compound, Early Intake Compound, South Fork Yard, Moccasin Compound, Moccasin Fish Hatchery, Oakdale Service Yard, Rock River Lime Plant, and Warnerville Service Yard.
Justification
Many of these facilities and infrastructure were constructed in the early 1900s to facilitate the construction of the Hetch Hetchy Regional Water System. Capital improvements are needed to provide employees and staff with safe, comfortable, and efficient facilities from which to work.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability.
Operating Impact
Disrepair of HHWP project workplaces, system buildings, and facilities has led to reduced asset utilization and efficiency. Disrepair of asset components has led to unsafe work conditions which are responded to immediately upon notification. Deteriorated or absent facilities do not attract skilled workers who are necessary to meet succession planning and sustainability objectives.

ASSETS: Represented asset families include O'Shaughnessy Dam (circa 1923) and Hetch Hetchy Reservoir; Cherry Valley Dam (circa 1956) and reservoir; Lake Eleanor Dam (circa 1918) and reservoir; Early Intake Dam (circa 1925); spillways, spillway gates, and controls; energy-dissipating components; spillway channels to 100 yards downstream; trash racks and debris removal systems; water outlet conduits, gates, valves, face valves, and control systems; dam foundations and abutments; drainage system galleries, pumps, and drain piping; primary/backup power, UPS' and batteries; lighting, mechanical, and HVAC systems; security and emergency communication systems; access roads and bridges; instrumentation and monitoring systems; and SCADA.
Justification
HHWP's four upcountry dams were built between 1918 and 1956 and are exhibiting expected wear and tear. California Division of Safety of Dams accepted HHWP's Dam Safety Program requirement for periodic condition assessments. Given the age of the dams, it is anticipated that major repairs, security enhancements, and emergency communication system upgrades will be necessary.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Unresolved dam safety deficiencies could influence California Division of Safety of Dams to issue dam operating restrictions, limiting the operating water surface elevation range, reducing the maximum water surface elevation, or increasing dam safety surveillance requirements. Water surface elevation restrictions could impact the SFPUC water supply, increasing the frequency and level of water restrictions on SFPUC water customers.

SCOPE: Deliver capital improvement projects to sustain the reliability of access roads and bridges that provide vehicular access to HHWP dams, reservoirs, water conveyance facilities, hydroelectric powerhouses, switchyards and substations, and communication sites.
PROJECT DESCRIPTION: HHWP has developed a program to extend the life of these assets. The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate. Typical capital projects include resurfacing, retaining wall construction, drainage improvements, slope stability improvement, guardrail installations and replacements, rockfall hazard mitigation, and bridge rehabilitation.
ASSETS: Represented asset families include improved and unimproved roadways; chip seal and asphaltic-cement pavements; guardrails; retaining walls and road embankments; drainage systems; rock retention/deflection systems; and bridges, piers, abutments, and foundations.
Justification
Necessary compliance and safety improvements must be performed on paved roads and small bridges that are used by HHWP staff and the general public.
HHWP is responsible for maintaining access roads to all upcountry facilities, electric transmission towers, and San Joaquin Pipelines. There are approximately 14 bridges, 40 miles of paved roadways, and hundreds of miles of unpaved roadways in the program. Paved roads are also used by the public. Periodic bridge inspections are necessary to prevent structural and foundation failures.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability.
Operating Impact
Failure of roads and bridges can impact access to HHWP facilities. Failure of roads and bridges can also impact public access to public and private lands adjacent to the Hetch Hetchy Right of Way.

SCOPE: Deliver capital renewal and replacement projects to implement and sustain physical security at critical assets. Fund physical security upgrades at existing HHWP facilities. The security at many HHWP Moccasin and remote facilities lack sufficient security measures to minimize the risk of intrusion.
PROJECT DESCRIPTION: This project will fund security system measures that meet capitalization thresholds, including access monitoring and controls, fencing, card access, and camera monitoring.
ASSETS: Represented asset families include all HHWP "Joint" facilities, e.g., chemical dosing facilities; water quality sampling facilities; water treatment plants; wastewater treatment plants; corporation yards; communication equipment buildings; network operating centers; remote and auxiliary control rooms; data centers; fences and gates.
Justification
Water and power are critical services. Physical security is required to limit access to these facilities. In addition, physical security at some HHWP Project locations is regulated under state and Federal law. Changes in current regulations may require upgrades to existing physical security systems.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability.
Operating Impact
Unauthorized access to these sites could jeopardize our water and power operations.

SCOPE: Deliver capital renewal and replacement projects to implement and sustain regional communication assets. Voice and data communications flow over multiple communication systems, including microwave, two-way radio voice, voice over internet protocol (VoIP), plain old telephone system (POTS), 900 MHz radio, fiber-optic communication, and information technology networks (corporate business network, SCADA network, and third-party networks).
PROJECT DESCRIPTION: HHWP has developed a program to extend the life of these assets prior to wholesale replacement. The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate. This project will enable HHWP to extend communications across dead zones to remote locations; replace obsolete technology in a strategic and planned approach; integrate voice and data services across the SFPUC; and modernize elements of the communication infrastructure to ensure serviceability, reliability, and, where pertinent, regulatory compliance.
ASSETS: Represented asset families include Warnerville Radio Shelter, Warnerville Substation, Albers Road Valve House, Mt. Allison, Roselle Crossover, San Joaquin Valve House, Tesla Portal, Oakdale Portal, Rock River, Red Mountain Bar West, Moccasin Peak Communication Site, West Portal, Priest Reservoir, Moccasin Radio Shelter, Moccasin Powerhouse, Moccasin Compound Server Building Datacenter, Duckwall Communications Site, Intake Radio Site, Jones Point, Intake Switchyard, Southfork Yard, Kirkwood Powerhouse, Holm Powerhouse, Cherry Compound, Cherry Pump Station, Eleanor Dam, Burn Out Ridge Communications Site, O'Shaughnessy Dam, Poopenaut Pass Communications Site, power systems, batteries, standby generators, power supplies, servers, network cards; antennas, wave guides, encoders/decoders, and SCADA.
Justification
HHWP Communication Systems enable essential command and control over the Hetch Hetchy Regional Water System, hydroelectric generation, and high-voltage transmission system. The communication system further integrates HHWP Water Operations with Water Supply and Treatment Division (for water) and neighboring Transmission Operators (power). Reliable communication systems support water and power system objectives. There are remote locations without reliable communications, where networked visibility would improve efficiencies in operations and personnel safety.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability.
Operating Impact
HHWP dispatch and remote-control center is located in Moccasin and is manned by the Power System Operators. From this location, system operators monitor reservoir water surface levels, dam safety instrumentation, water flow, hydroelectric generator production, electric transmission and distribution lines, and fire and life-safety systems. Operators dispatch personnel responding to routine and emergency conditions, and notify management of unplanned situations (e.g., wildland fires, floods, traffic accidents, and other emergencies). Reliable communications are essential for the safety of staff, and to operate the system from Yosemite National Park to Sunol Valley near San Francisco Bay Area.

Project Manager: Ata Radfar Current Active Phase: Pre-Construction Prior Approved Budget: $ 30,138,401 Proposed Budget: $ 30,138,401 Prior Approved Start: 02/03/2014 Proposed Start: 02/03/2014 Prior Approved Finish: 12/31/2030 Proposed Finish: 12/31/2030 Description
Canyon Power Tunnel was built over 45 years ago. A condition assessment was performed on the tunnel in 2009 and the tunnel is in generally good condition, except for the Hetchy Adit, a tunnel access point. Temporary repairs have been made to the plug at this adit twice (once in 1989 and once in 2009), but permanent repairs are needed to reduce leakage and increase reliability of the system. The project scope includes installation of a new reinforced concrete plug downstream of the existing plug.
During construction of Canyon Power Tunnel, the O’Shaughnessy Adit Access Bridge was built in 1960 to provide sole access over the Tuolumne River to Hetchy Adit. The bridge is approximately 84 feet long and is a four-span simply supported bridge with a timber deck and concrete piers. It is located
0.5-miles downstream of O’Shaughnessy Dam and provides one lane two-way access along the access road. The O’Shaughnessy Adit Access bridge, as the sole access point to Canyon Tunnel – Hetchy Adit, impacts the proposed work and also any urgent incidents inside Hetchy Adit. The bridge needs rehabilitation prior to adit work due to restricted load rating of the bridge.
Justification
The existing concrete plug in Hetchy Adit has been experiencing a leakage problem. Multiple attempts to fix the leakage have failed. If the plug is not replaced, water will continue to leak out and eventually lead to the collapse of the concrete plug structure. If the adit collapses, Canyon Tunnel will not be able to convey water which will affect both water deliveries to SFPUC customers and power generation. Also, the new plug will be equipped with a large access door to allow maintenance vehicle to enter the tunnel in case of emergency. This will help shorten the time of return of service.
O'Shaughnessy Adit Access bridge is not seismic resistant. The concrete foundation and piers have experiencing scaling of concrete due to stream flow exposing aggregate. Some parts of the wooden deck have rotted and need to be replaced. If the bridge collapses, it will cut off the only vehicular access to Hetchy Adit which leads to Canyon Tunnel.
Operating Impact
Failure at Hetchy Adit will impact water deliveries from the Tuolumne River to SFPUC water customers, reducing maximum deliveries from 310 mgd to about 80 mgd (maximum filtration capacity at Sunol Valley Water Treatment Plant for water from the Tuolumne River watershed). Failure of the O'Shaughnessy Adit Access bridge restricts access to Hetchy Adit and Canyon Tunnel.

This project will replace the existing wastewater treatment facilities with a Sequence Batch Reactor (SBR) plant. The proposed SBR “package plant” will be a two-train facility. Each train would have a capacity of 18,000 gallons per day to accommodate average daily dry-weather flow. The new plant will be provided with upgraded screening, flow monitoring, flow equalization, SCADA instrumentation and automation features. The existing plant must continue to serve the Moccasin community while the new plant is being installed and would remain in operation during construction.
Justification
The useful life for mechanical and electrical equipment in treatment facilities is typically 15 to 25 years, according to EPA and ASCE publications. Given the age and condition of the WWTP as well as its process and operational limitations, investing in improvements to address individual WWTP systems and component deficiencies is not practical in comparison to installation of a new replacement plant. At more than 45 years old, the Moccasin WWTP is at the end of its useful service life and is becoming increasingly maintenance-intensive.
Operating Impact
The existing WWTP is the only wastewater plant serving the Moccasin Compound. Failure could result in discharge of untreated wastewater into Moccasin Creek, which flows into Don Pedro Reservoir.

SCOPE: Mountain Tunnel (MT) was constructed between 1917 and 1925 and is a critical, nonredundant link in the Regional Water System, conveying SFPUC Tuolumne River water supply from Kirkwood Powerhouse to Priest Reservoir. Due to the tunnel's 90 years of operation, deferred maintenance, and construction deficiencies from the early 1900s, sections of the tunnel have deteriorated, some more extensively than others. The 2017 MT Inspection and Repairs Project provided an update to the Condition Assessment conducted in 2008. Short-term repairs were also made in 2017 and 2018 to reduce the risk of failures in the concrete lining prior to implementation of the long-term project. The MT Improvements (Rehabilitation) Project was selected for design and construction of the preferred engineering alternative that will keep this vital component of the Regional Water System in reliable service for years to come. The budget and schedule are based on the MT Improvement Project construction phase, which is anticipated to take place between 2021 and 2027. Note: This is the Joint portion of the MT project.
PROJECT DESCRIPTION: The Joint portion of the Mountain Tunnel Improvements consists of work related to the construction of the Flow Control Facility and Priest Adit Tunnel.
ASSETS: Mountain Tunnel
Justification
Continued tunnel lining degradation could lead to catastrophic failure. The likely type of anticipated failures are "local collapses," which would not impact power generation but would create water quality events in terms of turbidity in the water supply. The likelihood of localized collapses is moderate to high. Depending on the configuration of the system, this type of event could interrupt deliveries of the Tuolumne River supply to SFPUC water customers.
Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
Depending on the configuration of the system, a "local collapse" could interrupt delivery of Tuolumne River water to the SFPUC customers. Continual degradation of the asset could lead to a catastrophic failure.

SCOPE: Cherry Dam Spillway is a 334 foot-wide ogee-type concrete weir that discharges into an unlined adjacent channel. The spillway capacity is designed for 52,000 cfs. A spill of 1,500 cfs in 2010 resulted in significant erosion damage to the unlined spill channel, large- scale erosion along the western segment of Cherry Dam, and flooding of Cherry Power Tunnel Adit and a campground downstream. Engineering studies showed that remedial measures and erosion protection for the spill channel are needed to ensure that spill flows from Cherry Valley Dam spillway can be contained without erosion damage to the existing embankment dam and downstream area. Studies also found that long-term improvement to the spillway is needed to increase the hydraulic capacity of the spillway to safely pass the design flood. This project is a short-term interim solution until the long-term spillway improvements are implemented.
PROJECT DESCRIPTION: This project will re-establish containment for the breached spill channel section from the 2010 spill and install armoring to protect the upper spill channel section against erosion from spillway releases of up to 2,000 cubic feet per second.
ASSETS: Cherry Dam Spillway
Justification
The complete length of channel that passes water from the ogee side spillway to Cherry Creek is entirely unlined, which will result in continued erosion if subjected to even minimal spillway discharge. Erosion from a spillway release and a landslide in 2010 along the upper spill channel caused overtopping of the left bank and created a 1,500-feet long eroded channel to the Cherry Creek.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.
Operating Impact
Failure to adequately address this issue could result in an operation restriction from California Division of Safety of Dams, reducing maximum storage limits, and increasing frequency and level of rationing for SFPUC water customers.
Budget Change Yes Schedule Change Yes Scope Change Yes
Reason for Change
The change in scope, schedule and budget is a result of findings from an updated engineering study. This study determined that re-establishing the damaged spillway channel section would require additional armoring of the upper spill channel for protection against erosion from spillway discharges of up to 2,000 cubic feet per second. The addition to scope is adequate criteria to meet the objectives of this short-term interim improvement. The updated budget reflects this change, as well as normal escalation factors. The overall schedule was updated to include 6 months for closeout after the completion of the construction.

SCOPE: Eleanor Dam is a multiple-arch reinforced concrete dam that was constructed in the 1920s. The 2015-2016 Needs Assessment Report identified concerns related to deterioration and aging of the structure, inadequate spillway capacity, and dam safety. Specifically, structural/seismic concerns were identified regarding Eleanor Bridge, cracking and spalling of concrete, exposed rebar, significant leakage through the arch barrels, cracks and erosion of the spillway concrete, and insufficient spillway capacity to pass the design flood. The project scope will include the rehabilitation of the dam to address the identified deficiencies and replacement of the bridge across the top of the dam. The scope also includes an interim repair of the bridge to extend the service life until the bridge is replaced.
PROJECT DESCRIPTION: Immediate interim repairs to the bridge deck and girders will be performed. Long-Term mitigation alternatives include improvements to increase spill capacity to safely pass the design flood, installation of a liner on the upstream face of the dam, concrete repairs, valve replacement, and installation of concrete lining and riprap for foundation armoring, and replacement of the existing bridge.
ASSETS: Eleanor Dam
Justification
Eleanor dam and bridge structure is a critical asset that needs to be rehabilitated to restore deteriorating and aging elements of the bridge structure and to extend its service life until bridge replacement takes place concurrently with dam repairs/modifications.
For long-term, the SFPUC is responsible for developing and maintaining a mature dam safety management program. This project is intended to meet this dam safety objective.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.
Operating Impact
For public and operations safety, interim repairs to the existing concrete bridge deck will be performed in 2026 to extend the service life by 15 years until a permanent replacement is constructed.
For the long-term project, loss of operational functionality of this dam will result in reduction of carryover storage levels for SFPUC water customers and loss of water storage will impact the frequency and level of rationing for our SFPUC water customers. In addition, generation produced by water stored behind this dam contributes to about 15 percent of HHWP's annual generation.

SCOPE: Deliver capital improvement projects to sustain the reliability of HHWP's electric distribution lines. HHWP owns and maintains about 40 miles of distribution lines which power operational facilities on the HHWP Project. About 60 percent of the distribution system has exceeded its life expectancy, resulting in multiple failures at Moccasin Compound. In addition, new loads to support operations at Moccasin Compound and remote sites (e.g., UV systems, Moccasin Fish Hatchery Recirculation System, and new buildings/offices) are taxing the current system, requiring mitigation.
This project funds load studies and condition assessments to evaluate current and future needs; replacement of failing systems; design to meet current/future needs; and procurement of critical spare equipment to ensure reliable 24/7 water and power operations at Moccasin Compound and remote sites.
PROJECT DESCRIPTION: The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate, to sustain the reliability of the electric distribution system.
ASSETS: Represented asset families include circuit breakers; transformers; relays; capacitors; conductors; poles, cross-arms, tie-backs, anchors, and dead-ends; insulators and connectors; instrumentation and control systems; SCADA; and other power-distribution supporting infrastructure.
Justification
Interruptions in power delivery to HHWP Project facilities interrupts water and power systems' supervisory and control processes, impedes worker productivity, and interrupts computing processes. Capital improvements are needed to ensure reliable distribution power for current and future needs, to resolve nonstandard electric distribution conditions, and to increase operational flexibility.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability Operating Impact
Interruptions in power delivery to facilities interrupts water and power systems' supervisory and control processes and impedes worker productivity.

SCOPE: HHWP is responsible for maintaining 14 bridges within the HHWP Project. Condition assessments have identified needs for rehabilitation and/or replacement due to age and to meet current seismic design criteria. Two of fourteen bridges, Lake Eleanor Dam Bridge and O'Shaughnessy Adit Access Bridge, require substantial modification or replacement and have been combined into this project. Lake Eleanor Dam Bridge, constructed in 1918, is a structural component of Lake Eleanor Dam, which is integral to the structural/seismic integrity of the arch dam. O'Shaughnessy Adit Access Bridge was built in 1960. It is approximately 84 feet long and is a four-span simply supported bridge with a timber deck and concrete piers. It is downstream of O'Shaughnessy Dam and provides one lane two-way access to Canyon Tunnel. Due to limited funding, the current project is funded to include two bridges only: O'Shaughnessy Adit Access Bridge and Lake Eleanor Dam Bridge.
PROJECT DESCRIPTION: This project originally included rehabilitation and/or replacement of O'Shaughnessy Adit Access Bridge and Lake Eleanor Dam Bridge. O'Shaughnessy Adit Access Bridge is the only access to Canyon Tunnel Hetchy Adit. The proposed work relating to the bridge and adit will be implemented under a single construction contract. Thus, SFPUC decided to combine the rehabilitation of O'Shaughnessy Adit Access Bridge with the Canyon Tunnel Hetchy Adit (Project #10014108). At the same time, Eleanor Dam Bridge is an integral part of the Eleanor Dam. Thus, Eleanor Dam Bridge replacement will be included as part of the scope of Eleanor Dam Rehabilitation (Project #10030759). The current proposed budget for the Bridge Replacement project will cover the planning efforts performed on these two bridge sub-projects so far. The planning efforts of O'Shaughnessy Adit Access Bridge and Eleanor Dam Bridge will continue under Canyon Tunnel Hetchy Adit (Project #10014108) and Eleanor Dam Rehabilitation (Project #10030759), respectively.
ASSETS: O'Shaughnessy Adit Access Bridge and Lake Eleanor Dam Bridge.
Justification
Compliance-driven and safety improvements must be performed for these bridges used by HHWP staff and the general public.

Moccasin Penstock was built in the early 1920s and conveys water, nearly one mile from Moccasin Power Tunnel to Moccasin Powerhouse. Moccasin penstock serves as the sole link in conveying water from Priest Reservoir to Moccasin Reservoir. The penstocks contain segments of hammer-forged welded steel (HFWS) that has experienced failures in the past. This type of HFWS pipe has a history of brittle fracture failure at both Pacific Gas & Electric Company and Southern California Edison penstocks. In October 2022, Phased Array Ultrasonic Testing (PAUT) was used to evaluate hammer forged weld seams and visible cracks were discovered. In addition, issues have been identified regarding the anchor/saddle system with respect to alkali reactive silica, which degrades the concrete anchor blocks.
To mitigate potential risks, and avoid consequences of failure, SFPUC is considering replacing the penstocks. Based on a preliminary study, a combination of a drop shaft, a tunnel and above grade pipes appears to be a favorable alternative. SFPUC will continue the study before determining the most appropriate alternative solution. For capital planning purposes, SFPUC assumes the alternative will include the following major elements: a drop shaft of about 850 feet deep, a new tunnel penstock of about 3,100 feet, and two 72 in. above-grade penstocks with a total length of 3,000 feet.
Also, the project will construct a Removable Spool Piece (RSP) downstream of the West Portal Valve house (WPVH) that will provide safe isolation for each penstock. Moccasin Penstock RSP work consists of a new 4-5’ long, ~110” Dia RSP located downstream of the WPVH using a Victaulic coupling.
New upstream and downstream grooved-end pipe spools will be welded directly to the existing 102” U1/U2 penstock riveted steel pipe.
Justification
The goal is to provide a reliable redundant conveyance with a 100-year life span.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Operating Impacts, Environmental Stewardship, and Sustainability.
Operating Impact
The Moccasin penstock system is a critical asset in the Hetch Hetchy conveyance system and there is no existing bypass around the penstocks. The initial risk assessment identified potential modes of failure as: transient event, structural failure, and seismic event. The potential consequences of failure are loss of water supply to the SFPUC Regional Water System, loss of water for power generation, erosion and undermining of adjacent infrastructure, damage to downstream facilities and infrastructure, and downstream safety hazard. Failure of one or more penstocks will cause flooding, potentially resulting in damage to Moccasin facilities, and jeopardizing the safety of employees and residents of Moccasin.

Reason for Change
With respect to the last CIP, the proposed construction estimate has drastically changed. Previous CIP only included an estimate that was developed in early stages of planning and during the alternative analysis phase. Thus, with a selected alternative upon completion of alternatives evaluation exercise, a more refined construction estimate is developed.

SCOPE: A heavy storm event in 2018 caused significant damage to the auxiliary spillway, upstream trash rack and diversion, and downstream area.
Subsequent engineering studies concluded that improvements are needed to increase the spillway capacity to safely pass the updated design flood without overtopping the existing embankment dam. This project is needed for dam safety.
PROJECT DESCRIPTION: This project will construct a new concrete auxiliary spillway with adequate flow capacity along the alignment of the existing auxiliary spillway and additional flood protection to Moccasin Dam and downstream facilities, including the Moccasin Lowhead Powerhouse, the Moccasin Fish Hatchery, and Moccasin wastewater treatment plant.
ASSETS: Moccasin Dam
Justification
This project is intended to ensure water quality, reliable water delivery, and dam safety.
Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Environmental Stewardship.
Operating Impact
Moccasin Dam is in satisfactory condition; however, the spillway is undersized and is not capable of passing the updated design flood that resulted from the March 2018 storm. The dam is fit for service; however capital investment is required to increase the spillway capacity of the facility. Currently the California Division of Safety of Dams has imposed maximum reservoir elevation operating restrictions, limiting the use of flashboards on the spillway. Use of these flashboards increases storage capacity during maintenance and construction projects (e.g., Mountain Tunnel Rehabilitation).
Following completion of this project, the California Division of Safety of Dams will remove current elevation restrictions, increasing operational flexibility.
Budget Change Yes Schedule Change Yes Scope Change No
Reason for Change
The change in budget and schedule is a result of the findings and analysis completed during the Conceptual Engineering Report when conceptual design was completed which included an AACE Class IV estimate and an updated design and construction schedule. The higher cost reflects better definition of the project scope, site constraints, and market condition changes. The schedule also changed because the environmental review changed from an anticipated Environmental Impact Report (EIR) to a Mitigated Negative Declaration (MND).

SCOPE: The project will repair a failed section of ramp and improve the remaining O'Shaughnessy boat ramp/dock to provide reliable all-season access to the reservoir for HHWP Operations and National Park Service Law Enforcement activities.
PROJECT DESCRIPTION: Assess the condition of the existing access road, boat ramp, and floating dock; develop an alternatives analysis and preferred recommendation; design and permit improvements; and construct the permitted designs.
ASSETS: Represented asset families include Hetch Hetchy Reservoir boat ramp, boat ramp access road, boat dock, and anchorage system.
Justification
The existing boat ramp is a one-way, steep, narrow, gravel, single-lane access road and ramp connecting the reservoir with the main service road. The access road and ramp are used to place and retrieve boats, maintain the boats, and launch the boats year-round. The boat ramp surface and retaining walls (gabion baskets) have failed, resulting in difficult access for personnel to safely traverse either in single vehicles or when backing a trailered boat along the road.
Water Level of Service Goal(s) Supported: Drinking Water Quality.
Operating Impact
The all-season boat ramp is necessary to access the reservoir to perform water quality monitoring and sampling to meet regulatory requirements. The boat ramp is also required for law enforcement to access the reservoir to enforce National Park security and regulatory requirements for the reservoir and tributaries.
Budget Change Yes Schedule Change Yes Scope Change No
Reason for Change
This project was delayed due to unforeseen conditions in the field that required a re-review of the design. The schedule delay was exacerbated by a limited construction window due to weather conditions.
Budget was updated to reflect the amount needed to upgrade the retaining wall and install road base/driving surface. Additional funding (and time) will be needed if this project will continue to include re-paving the boat ramp with concrete.

SCOPE: HHWP Project operations and administration is located in Moccasin, California, with facilities including buildings, office trailers, warehouses, shops, laboratories, and sheds. Many existing facilities are deteriorating, do not meet current building codes, and are incurring increased maintenance costs. Investment in new facilities is needed to meet all applicable codes and standards; reduce maintenance costs; increase employee interconnectivity and productivity; provide appropriate, safe working space for staff, storage of materials, records, and equipment; and meet energy-efficiency standards. HHWP prepared a report titled "Moccasin Facilities Upgrade Project Alternatives Analysis and Evaluation Report Update" (AECOM WRE JV, July 2020). The report identified long-term needs for creating adequate office space for current staff in Moccasin. In addition, the report evaluated the needs for new, dedicated materials storage space, new records and archives space with offices, new space for servers, and parking space for staff.
PROJECT DESCRIPTION: The Moccasin Engineering and Records Building project will address the need for permanent office space by constructing a new two-story building. Hetch Hetchy and Infrastructure staff are currently located in temporary trailers that have exceeded their useful life (as noted in the 2020 AAR provided by AECOM). The new building will provide office space for Hetch Hetchy Engineering, Records, Energy Services, Infrastructure, and ITS staff. The scope also includes a secure server room, parking lot, and archive/records storage. The budget and schedule for the project will be modified to provide permanent office space for both Hetch Hetchy and Infrastructure staff and to address escalation since the completion of the 2020 Alternatives Analysis Report estimate.
ASSETS: Moccasin Engineering and Records Building.
Justification
Staff currently work in trailers that are beyond their useful life and require frequent repairs. A permanent building is needed to provide adequate offices to meet long-term needs.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability.
Operating Impact
Disrepair of existing modular facilities has led to reduced efficiency and potentially unsafe work environments. Deteriorated and cramped facilities do not attract skilled workers who are necessary to meet succession planning objectives. Additionally, maintaining access to information archives is a core function to meet operational objectives. Efficient recovery of documents such as construction contracts, as-builts, and O&M manuals, is important for ongoing operations, maintenance, and capital project execution.

SCOPE: Deliver capital improvement projects to sustain the reliability of HHWP's water conveyance assets from the reservoir intake structure/tower or dam's isolation valve to the powerhouse turbine isolation valves. Water is conveyed from upcountry reservoirs to the hydroelectric powerhouses via a network of tunnels, pipelines, penstocks, and canals, through valves, gates, portals, penstocks, and reservoir bypasses. NOTE: this project addresses reliability improvements for water conveyance from Eleanor, Cherry, and O'Shaughnessy reservoirs to Kirkwood and Moccasin Powerhouses. The R&R Water Conveyance Life Extension (Water), the R&R Water Conveyance Life Extension (Power), and the SJPL Life Extension Project address reliability improvements for other water conveyance assets on the HHWP Project.
PROJECT DESCRIPTION: HHWP has developed a program to extend the life of water conveyance assets prior to wholesale replacement. The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate, to sustain the reliability of water conveyance assets with capital improvements.
ASSETS: Examples of facilities classified as joint funded water conveyance assets include Canyon Tunnel and adits; Canyon Portal; Mountain Tunnel Headgates; Early Intake Bypass; Mountain Tunnel Diversion Access at Early Intake; Mountain Tunnel shafts and adits; South Fork Crossing and adits; Priest Reservoir Bypass; overflow shafts and surge shafts; sand traps; valves, gates, and actuators; and associated power systems.
Justification
Some of the water conveyance system is well beyond the original service life. Proactive evaluation of water conveyance assets and planned capital investments reduce the water delivery curtailments and interruptions in water delivery.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability.
Operating Impact
Loss or reduced capacity of any one of these facilities would impair the ability of SFPUC to deliver water from the Tuolumne River to SFPUC customers.

SCOPE: The SFPUC owns assets in areas designated by Cal Fire as "High Fire Threat Zones." This project will mitigate the risk posed by uncontrolled wildfire to "Joint" assets by constructing fuel breaks near HHWP Project facilities. This project does not fund annual vegetation management plans.
PROJECT DESCRIPTION: The project includes the construction of fuel breaks and fuels reduction projects adjacent to HHWP Project facilities to provide protection of "Joint" assets.
ASSETS: HHWP Right of Way and facilities classified as "Joint" assets.
Justification
Shaded fuel breaks act as a defensible landscape to reduce fire speed and severity and to improve suppression by ground and air fire crews. Fuel breaks accomplish this by controlling fire behavior by reducing ladder fuels (fuels low to the ground that can cause the fire to "ladder" up trees and vegetation and spread across treetops); opening up the forest canopy; and reducing ground fuels. Fuel breaks are designed not to control a fire, but to provide points of access to control the flanks of a fire and provide possible backfire action in the face of an advancing fire head.
Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.
Operating Impact
HHWP's wildfire mitigation projects will vary by asset, location and terrain. Wildfire is continuing to become more prevalent in California, requiring additional resources to mitigate risks and maintain operations.

SCOPE: In May 2017, the CCSF Board of Supervisors approved ordinance 115-17, amending the existing Administrative and Environmental Codes to require (1) that any new passenger vehicle procured for the City fleet be a Zero Emission Vehicle; (2) that all passenger vehicles in the City fleet be Zero Emission Vehicles by December 31, 2022; and (3) encourage selection of Zero Emission Vehicles in other classes as technology improves. This Project will evaluate the suitability of electrifying HHWP's vehicle fleet. The Project funding provides for a suitability study, planning and conceptual design of new eVehicle charging infrastructure complying with Ordinance 115-17. This will also comply with California Air Resources Board’s Advanced Clean Fleet Regulations which currently requires that 50% of medium and heavy duty vehicle purchases be ZEV, and 100% of purchases be ZEV by 2030. Although HHW has purchased ZEV vehicles to comply with the mandate, the HHWP Project lacks distribution capacity and charging infrastructure to maintain this fleet for continued reliable operations, and fleet readiness, particularly during emergencies.
PROJECT DESCRIPTION: Perform suitability study for electrifying HHWP's fleet, i.e., vehicle uses, evaluation of mileage (per trip and per day), load requirements, areas of operation, use during emergencies and power outages. Based on the findings determine vehicle specifications, i.e., engine range (miles per charge) and charging capability. Given suitability and vehicle recommendations evaluate charging infrastructure required to support the effort, i.e., estimated electrical load demand, local electric distribution capacity, develop site- specific project scopes of work, conceptual design site improvements.
ASSETS: Represented asset families include electric distribution systems at Cherry Compound, O'Shaughnessy Compound, Early Intake Compound, South Fork Yard, Moccasin Compound (and Priest), Holm Powerhouse, Kirkwood Powerhouse, Moccasin Powerhouse, Oakdale Portal, crossovers and throttling stations, Warnerville Substation, Oakdale Yard, Tesla, and Calaveras Substation. New assets will include CCSF standardized eVehicle charging stations, parking lots, overhead photovoltaic panels, transformers, meters, industrial energy storage devices and batteries, switchgear, RTUs, communication equipment, and security systems.

SCOPE: The existing Moccasin Old Powerhouse was constructed in 1926 and abandoned in the 1960s. The building has multiple structural and nonstructural issues (including cracks, spalling of structural concrete, water intrusion, broken windows, settlement, hazardous materials, and seismic deficiencies) and has been pegged for demolition. The building is currently used for storage of large equipment and critical spares for the Hetch Hetchy Water and Power system.
The existing Moccasin Warehouse is over 55 years old, dilapidated, and without proper HVAC compromising the shelf life of multiple items that are regularly stored in the warehouse. Additionally, the lack of HVAC causes undue physical hardship on the staff who work up to 12-hour days in the heat. The building is also without adequate fire protection, exposing the staff and stored components to potentially hazardous conditions. The storage capacity for this building has been maxed out for quite some time, forcing Operations to utilize multiple satellite storage locations to secure the overflow.
PROJECT DESCRIPTION: Construct a New Warehouse (15,000 - 20,000 sf) within the Moccasin campus to consolidate storage from the Old Powerhouse, Old Warehouse and various satellite storage locations across the Moccasin Campus. The new building will be fully sprinkled per the San Francisco Building code and equipped with functioning HVAC and Wi-Fi to modernize warehouse operations.
ASSETS: This project will result in a new asset (Moccasin Warehouse Building).
Justification
A new warehouse is necessary to store critical spare equipment for the safe reliable operation of the Hetch Hetchy Water and Power system. The Old Moccasin Powerhouse that was used for storage of these critical spares is no longer suitable for this purpose due to the hazardous materials within the building and the structural deficiencies that are present. The Old Warehouse is no longer suitable due to its aging condition and limited square footage.
Operating Impact
Impact to safe reliable operation of Hetch Hetchy Water and Power assets if critical spare equipment is not available due to lack of suitable warehouse storage.
Budget Change Yes Schedule Change Yes Scope Change Yes
Reason for Change
Scope: Per the last CIP, the scope was to provide a viable Warehouse (9,000sf) to accommodate equipment stored in the Old Powerhouse. Upon review of the AAR, it was noted that a larger Warehouse would be necessary to consolidate items stored in the Old Warehouse, Old Powerhouse, and multiple satellite storage locations across the Moccasin campus.
Budget: The change in budget is due to the need of a larger Warehouse (from 9,000sf to 20,000sf).
Schedule: The schedule is expected to be shorter than what was provided in the FY 23-24 Capital Plan by approximately one year. Reallocation of funding to a reduced timeline is recommended to streamline the schedule.

Description
SCOPE: Engineering evaluations by the consultant Stantec Engineering in February 2019 identified deficiencies with the existing spillway capacity to accommodate updated design flood and requires remediation to meet design flood event. This project is needed for dam safety.
PROJECT DESCRIPTION: This project will increase spillway capacity to safely pass the updated design flood without overtopping the existing embankment dam.
ASSETS: Cherry Dam
Justification
This project is intended to ensure long-term dam safety.
Water Level of Service Goal(s) Supported: Regional Seismic Reliability, Regional Delivery Reliability, Water Supply, and Sustainability.
Operating Impact
The Needs Assessment Report shows that the Cherry Dam Spillway is not capable of passing the updated design flood and will not meet regulatory requirements. Design models have identified conditions that will lead to overtopping and erosion of the earth fill dam. It is necessary to increase the spillway channel capacity to eliminate overtopping and to prevent dam failure. If unresolved, DSOD will impose an operating restriction on the dam that will limit power generation and carryover storage for SFPUC water customers.

Description
SCOPE: Installation of two (2) micro-hydro generation units inside O'Shaughnessy Dam, supplied by the Instream Flow Release (IFR) pipes in the diversion tunnel upstream of the IFR valves. These units would provide a primary power source for the estimated 128 kilowatts of total capacity required for O’Shaughnessy Dam operations and O'Shaughnessy Compound, with redundancy to supply camp during any maintenance required on generation units.
PROJECT DESCRIPTION: The project includes tie-in to the existing IFR pipes, two (2) 36-inch turbine inlet valves upstream of each unit, two (2) downstream isolation valves downstream of each unit, two (2) hydraulic power units, medium voltage switch gear, and PLC based controls.
ASSETS: O’Shaughnessy Power Distribution System
Justification
Installation of these units reduces the SFPUC’s wildland fire risk by allowing for the de-energization or removal of the existing overhead power distribution lines between Camp Mather and O’Shaughnessy Compound. Removal of the overhead lines would reduce annual maintenance costs associated with the overhead power lines and increase dependance on a backup generator system for dam operations when the micro-hydro units were unavailable. This project does not change wildland fire risk between Kirkwood Powerhouse and Camp Mather.
Water Level of Service Goal(s) Supported: Regional Delivery Reliability.
Operating Impact
This project will result in a reduction of wildfire risk, reduced operations & maintenance on the distribution lines, and will provide reliable power for O’Shaughnessy Dam and Compound.

A significant part of the SFPUC's Information Technology (IT) infrastructure was implemented when headquarters moved to 525 Golden Gate Avenue in 2012. Much of the infrastructure implemented in 2012, which includes networking, telephony, conference room A/V equipment, etc., has surpassed its useful life. As a result, the likelihood of failure, not to mention cybersecurity risk, increases with the aging infrastructure. The purpose of this request is to fund the replacement, upgrade, and improvement of critical IT components/systems to mitigate these risks and provide higher levels of efficiency, reliability, and security. The Capital Plan request is comprised of the following projects, each focused on a specific area of IT infrastructure:
1. Network Infrastructure Upgrade
2. Server Infrastructure Upgrade
3. SCADA Infrastructure Upgrade
4. Phone Migration
5. 525GG Conference Room Refresh
6. Cybersecurity Improvements
7. SFPUC.GOV Migration
8. Maximo Upgrade
9. Application Enhancements (ServiceNow, GIS & Data Maturity)
10. Questica Implementation
Justification
Much of the current IT Infrastructure has surpassed its useful life. As a result, the likelihood of failure and cybersecurity risk, increases with the aging infrastructure. Upgrade, enhancement, or replacement of critical ITS Infrastructure components is needed to ensure uninterrupted, reliable, and secure technology resources are available to the entire organization.
Operating Impact
Water, Wastewater and Power increasingly relies on IT infrastructure to perform day-to-day operations. Failure of IT Infrastructure can impair the SFPUC's ability to provide water, power and properly treat wastewater, which can lead to risk in the areas of water quality/environmental, public health and safety.

Description
Through a collaborative effort, PUC HRS and ITS have been working together since last fiscal year with the goal of updating HRS’s critical IT infrastructure that has surpassed its useful life and at risk of failure. As a result of this collaborative effort, the Capital Plan request is for a Workforce and Talent Management System/ecosystem that fuels smarter decisions with data, enhances the user experience with efficiency and simplicity, and advances growth through integrated technology.
Justification
The expectations of human resources are evolving from service-oriented and operational focused to strategic partnership focused. To transform PUC HRS into a strategic partner, we must improve operational efficiency and increase strategic impact. The Workforce and Talent Management System is needed to replace fragmented, outdated existing HR IT infrastructure that limits accuracy, compliance, and the ability to manage a complex essential-services workforce. It will provide the modern tool and analytics required for an efficient, modern HR and a better employee experience, enabling the SFPUC to meet is core mission more reliably.
We are requesting funding for the purchase and implementation of a modern, cloud-based Workforce and Talent Management System platform. This system will replace HRS’s current ITS infrastructure that has surpassed its useful life and is at reach of failure in order to support the SFPUC’s most crucial resource: its people. This system will support efficient core HR functions, improve data accuracy, and align with departmental goals for digital transformation and operational excellence.
Operating Impact
This initiative aligns with our broader strategic goals of attracting and hiring great people, developing transformational leaders, fostering fulfilling careers, shaping a positive and safe employee experience, and cultivating strategic partnerships using people analytics to inform business objectives.
By addressing our HR systems needs comprehensively and strategically, we aim to enhance overall efficiency and drive organizational excellence. This approach reflects our commitment to making a well-informed investment in critical HR IT infrastructure, that will propel PUC forward in optimizing HR functionalities.

The SFPUC currently provides about 55 megawatts (MW) of electricity to the San Francisco International Airport (SFO) at transmission level voltage of 115 kilovolts (kV) through two existing 115-kV transmission substations, one located in Millbrae, CA and the other in San Bruno, CA. SFO expects their electric load to increase to 247 MW by the year 2065 due to annual passenger increase and associated guest services, increasing electrical vehicle usage, conversion from gas to electric operations, and to meet Airport, City, and State decarbonization goals and regulations. To provide for the load increase, the existing SFPUC transmission substations, Airport Substation and Substation MA, need to be upgraded. The Airport is expected to fund the construction of an additional new substation as a separate project.
Justification
The SFO Substation Improvements project allows the SFPUC to continue to serve SFO and the anticipated load increase at SFO from 55 MW to 247 MW. The project will plan, design, and construct needed electric facilities at SFO and allow SFO to continue to receive safe, reliable, low cost Hetch Hetchy power that is 100 percent greenhouse gas free from SFPUC.
Operating Impact
Failure to fund this project will result in the inability to electrify new projects to support increasing airport loads and fulfill the City's net zero carbon emission goals. The annual operating and maintenance costs of the existing substations are not expected to materially increase as a result of these upgrades.

Distribution Interface - Redevelopment provides for the design and construction of new electric duct banks and 12-kilovolt (kV) underground electric distribution systems for the SFPUC to provide electric services to various new developments within San Francisco, including Mission Rock, Pier 70, Hunters Point, Candlestick Point, India Basin, Sunnydale HOPE SF, Potrero HOPE SF and Visitacion Valley. Master developers pay for the installation of required infrastructure and substructures for new underground systems that include, but are not limited to, the following: utility joint trench, duct banks, conduits and pull wires, utility vaults and pull boxes, and transformer pads. The SFPUC, as the electric utility provider, installs the conductors in the conduits, transformers, switches, and metering equipment required for the electric distribution systems. The costs include the installation of temporary replacement 12-kV overhead distribution facilities as needed.
Justification
The Distribution Interface-Redevelopment project is consistent with the SFPUC's role as the exclusive electric service provider in redevelopment areas.
It benefits SFPUC by constructing new electric distribution infrastructure to support new redevelopment projects. The new SFPUC-owned distribution system avoids relying on Pacific Gas & Electric Company (PG&E) for costly interconnection, including the Income Tax Component of Construction (ITCC) at 22-34% of the total cost, as well as the cost to own and operate the equipment at 0.60% per month or 7.2% per year for the life of the equipment.
Other benefits include the ability to implement the City's and SFPUC's climate objectives, SFPUC customers receiving greenhouse gas-free energy at competitive electric rates, and increases in SFPUC’s customer base and associated revenue.
Operating Impact
Operating impact includes avoiding costly PG&E interconnection, including ongoing operating costs and ITCC. Existing 12-kV electric distribution systems that are antiquated will need to be relocated and undergrounded as part of new developments. Completed redevelopment projects will require qualified staff for operations and maintenance. SFPUC must allocate resources for system monitoring, maintenance, repair, and troubleshooting to ensure reliability and resiliency. The costs to serve and anticipated revenues from the new customers are incorporated and accounted for in SFPUC’s Financial Plan.

HHP-Intervening Facilities delivers Hetch Hetchy Power to customers that the SFPUC is serving under Pacific Gas & Electric Company's (PG&E) Wholesale Distribution Tariff (WDT). It includes funding to interconnect SFPUC’s customers to PG&E’s distribution lines through the furnishing and installation of intervening facilities such as metering points, protective devices, and disconnection means. Intervening facilities demarcate the change in ownership and maintenance responsibilities between two different utilities, in this case PG&E and SFPUC.
Justification
PG&E requires intervening facilities whenever SFPUC interconnects with the PG&E-owned grid. SFPUC has been required to access the PG&E-owned grid through WDT connections since the expiration of the Interconnection Agreement with PG&E in 2015. The furnishing and installation of intervening facilities is the only way SFPUC can transmit Hetch Hetchy Power to our end users over PG&E lines and circuits.
Operating Impact
Without intervening facilities, PG&E will refuse to transmit Hetch Hetchy Power over their distribution system. Municipal customers with power needs would need to sign up for retail electric service from PG&E, and SFPUC would no longer be the power provider. SFPUC would lose the associated revenue, reducing the funds available to operate and maintain power facilities in-city and upcountry, as well as reducing funding that supports jointly financed water and power facilities. This would create significant problems for water deliveries in addition to increasing rates and reducing reliability for remaining Hetch Hetchy Power customers.

This project provides for the second phase of development at Hunters Point Shipyard, Candlestick Point, and the Alice Griffith Housing Complex. The project will require the installation of new underground 12-kilovolt (kV) electrical distribution systems in all three areas. The HPS Phase 2 service will use the underground 12-kV electric distribution that was installed as part of Phase 1 and replace the existing overhead 12-kV system in place. The development project team comprised of the Office of Community Investment and Infrastructure (OCII) and the master developer (Lennar) will pay for the installation of the infrastructure and substructures required for the new 12-kV underground electric distribution system that includes, but is not limited to, the following: utility joint trench, duct banks, conduits and pull wires, utility vaults and pull boxes, and transformer pads. The SFPUC as the electric utility provider will install the conductors in the conduits, transformers, switches, and metering equipment required for the electric distribution system. The costs include the installation of temporary replacement 12-kV overhead distribution facilities as needed and provides for the implementation of energy efficiency and renewable program incentives. The project will also look into the feasibility and implementation of a supervisory control and data acquisition (SCADA) system, automated metering information (AMI) system, and integration of both with other technologies into a possible smart grid electric system.
Justification
This project is consistent with the SFPUC's role as the exclusive electric service provider to Hunters Point Shipyard and will utilize existing 12-kV electric service points as well as the existing 12-kV underground electric distribution system.
Operating Impact
The existing overhead 12-kV electric distribution system at Hunters Point Shipyard, Candlestick Point, and Alice Griffith Housing Complex are not capable of supporting the electrical needs of the new development project and will need to be relocated underground. The costs to serve and anticipated revenues from the new customers are incorporated and accounted for, as appropriate, in the Financial Plan.

Project Manager: Michael L Clark Current Active Phase: Pre-Construction Prior Approved Budget: $ 1,000,000 Proposed Budget: $ 23,806 Prior Approved Start: 07/01/2022 Proposed Start: 07/01/2022 Prior Approved Finish: 06/30/2026 Proposed Finish: 06/30/2026 Description
This project will provide new transmission and distribution level facilities to effectively and efficiently serve affordable housing customers as well as other possible retail, commercial, and municipal customers. This project is critical for San Francisco to provide electric services to its affordable housing and other customers as a direct result of the delays and interconnection issues associated with Pacific Gas and Electric Company's discretion in its implementation of its wholesale distribution tariff (WDT). Pacific Gas & Electric Company has severely compromised San Francisco's ability to meet redevelopment customer load requirements by providing only about 18 megawatts (MW) of the 60 MW of capacity needed to serve the HOPE SF affordable housing development projects at Alice Griffith, Potrero, and Sunnydale. The India Basin and Candlestick Point sites are also lacking the needed approved capacity to operate at full build out.
Justification
SFPUC is obligated to serve this load in a timely manner so as not to slow project timelines and impede the City's priority to build more affordable housing. Failure to connect this load on schedule would also result in a budget shortfall due to SFPUC's inability to serve these customers as well as possible liquidated damages imposed by developers. Power will continue to seek the needed capacity from Pacific Gas & Electric Company, but recent efforts to obtain such agreements in a timely manner have failed.
Operating Impact
The implementation of this project will provide solutions to proactively manage and mitigate capital and operational impacts to San Francisco's ability to adequately, effectively, and efficiently serve its customers. It also would limit San Francisco's exposure to delays and costs uncertainties associated with Pacific Gas & Electric Company's WDT and reduce, if not eliminate its reliance on Pacific Gas & Electric Company and budget shortfalls with the inability to secure adequate WDT service.

Grid Connections allows SFPUC to connect its Hetch Hetchy Power customers to the electrical circuits and equipment owned, operated, and maintained by SFPUC. This includes planning, design, and construction of new interconnections, as well as upgrades needed to improve the SFPUC-owned electric grid.
Justification
Grid Connections allows increased and more reliable service to our customers and thus better utilization of clean energy from Hetch Hetchy generation. It is easier and less expensive for our customers to connect to the SFPUC-owned grid rather than accessing Pacific Gas & Electric Company’s (PG&E) grid, particularly when PG&E requires connection under the terms of their Wholesale Distribution Tariff (WDT). Grid Connections funding is needed to fully realize the potential of SFPUC’s owned grid infrastructure and provide clean power to customers more efficiently and at much lower cost.
Operating Impact
Grid Connections avoids significant costs associated with PG&E WDT service. The cost to connect via WDT often means paying PG&E double the cost to install, own, operate and maintain electric circuits and equipment to serve City facilities and buildings. This includes both the associated Income Tax Component of Construction (ITCC) at 22-34% of the total project cost, as well as PG&E costs to own and operate the equipment at 0.60% per month or
7.2% per year for the life of the equipment.
Budget Change Yes Schedule Change Yes Scope Change Yes
Reason for Change
Budget and schedule have been adjusted in earlier years for deliverability. Scope has been added for additional grid connections projects in outlying years.

The Spear Street Substation project includes a new 230kV transmission service from PG&E's Potrero Substation, a new transmission substation located at Spear Street, and a segment of a distribution duct bank (constructed by San Francisco Bay Ferry) which will run from the substation across Embarcadero Street. This project also includes staff time to review and coordinate with San Francisco Bay Ferry on an interim project to provide service to San Francisco Bay Ferry’s Downtown Ferry Terminal by 2028, before Spear Street is complete.
Justification
The Port of San Francisco is in the process of developing the waterfront. Additionally, regulation from the California Air Resource Board require short haul passenger ferries to switch to all-electric. As a result, additional electric power is needed at San Francisco ports and piers. Serving these additional loads require significant electrical infrastructure improvements to be constructed. These infrastructure improvements contribute to decarbonization while providing clean, affordable, and reliable power. The project will grow SFPUC's customer base and provide additional revenue opportunities. The Port is a current municipal Hetch Hetchy Power Customer. If SFPUC does not construct the infrastructure to serve these growing loads, the customer will need to construct and deed the infrastructure improvements to Pacific Gas & Electric Company at considerable cost to the City.
Operating Impact
The completed project will require qualified staff to operate and maintain the high-voltage substation and associated infrastructure. SFPUC must allocate resources for system monitoring, maintenance, repair, and troubleshooting to ensure reliability and resiliency. The project expands SFPUC’s customer base and revenue, and it will require long-term planning for efficient grid management. The costs to serve and anticipated revenues from the new customers are incorporated and accounted for in SFPUC’s Financial Plan.
Budget Change Yes Schedule Change Yes Scope Change Yes
Reason for Change
Project name changed from Downtown Ferry & South Beach Electrification. Budget, schedule, and scope updated to reflect transmission interconnection at PG&E’s Potrero Substation rather than Embarcadero Substation, adding approximately three miles of transmission. Schedule also revised to incorporate current long lead times for 230 kV transformers and breakers.

The Bay Corridor Transmission Distribution (BCTD) Backup Loop increases the reliability of customers served from SFPUC’s Davidson Substation by constructing a redundant electrical loop from Davidson to Mission Bay. This will allow for rerouting of power around faults and avoids outages when performing routine repairs on SFPUC grid facilities. The BCTD Backup Loop project design includes provisions for a separate future project to extend SFPUC distribution grid facilities from Mission Bay to the future Spear Street Substation's southernmost distribution network.
Justification
Under the current configuration of a singular duct bank running between the Davidson Substation and Mission Rock, replacing damaged cables or performing routine maintenance may necessitate system outages. The BCTD Backup Loop investment will introduce redundancy, strengthen system resilience, and enable targeted repairs with minimal disruption to customers.
Operating Impact
This project increases flexibility for operations and repairs by providing an alternative path to convey power from the Davidson Substation to customers. As with all new infrastructure assets, SFPUC must plan to provide additional staffing and resources for effective and efficient operations and maintenance.

Project Manager: Manuel Ramirez Current Active Phase: Construction Prior Approved Budget: $ 9,632,280 Proposed Budget: $ 93,786,524 Prior Approved Start: 07/01/2022 Proposed Start: 07/01/2022 Prior Approved Finish: 06/30/2033 Proposed Finish: 06/30/2036 Description
The development of Treasure Island and Yerba Buena Island (TI&YBI) includes a new underground 12-kV electrical distribution system on-island, replacing the existing overhead 12-kV system. The master developer will pay for the installation of the new underground 12-kV electric distribution system that includes the installation of the utility trench, the duct banks, conduits and pull wires, utility vaults, and transformer pads. The SFPUC as the electric utility provider will be responsible for installing the wires in the conduits, transformers, switches, and metering equipment and connecting the existing electrical distribution system with the new system. The cost to relocate the existing overhead 12-kV electric distribution system, interconnect and transition facilities between the new and existing system, and installation of temporary facilities needed for construction will be the responsibility of the master developer. The project also funds off-island electrical upgrades to meet increased demand on TI&YBI.
Justification
This project is consistent with the SFPUC continuing as the electric service provider at TI&YBI. The existing overhead 12-kV electric distribution system serving TI&YBI is antiquated and will not support the new development.
Operating Impact
By installing a new distribution system, the SFPUC will avoid providing electric service through Pacific Gas & Electric Company (PG&E) and avoid unnecessary income taxes and other operating costs associated with PG&E. As with all new infrastructure assets, SFPUC must plan to provide additional staffing and resources for effective and efficient operations and maintenance.

SFPUC-owned incandescent and mercury vapor streetlights are currently operated through high voltage series loop systems that are energy inefficient and no longer supported by manufacturers. In a series loop, the entire system fails when the loop breaks. This project aims to replace an inefficient lighting system through the conversion of high voltage series loop circuits into multiple standard voltage services and replace fixtures with LEDs.
Justification
This project is consistent with SFPUC's Technology Policy by utilizing current lighting codes to improve street lights' system reliability and economic value. The age and deteriorated condition of the systems posed serious reliability issues and caused prolonged downtime due to difficulty to repair a component or part of the system. The budget request would allow the conversion of approximately 54,000 circuit feet of high voltage series loop systems to multiple standard voltage services for all locations in San Francisco.
Operating Impact
Regular maintenance is costly because the series loop circuit conduits and cables are old and will continue to fail over time. The conversion would also reduce operation, maintenance and energy costs.

This project fosters a citywide pedestrian-friendly environment by installing streetlights 16 to 18 feet above the sidewalk. The addition of pedestrian lighting does not require complete re-design of current area lighting infrastructure. SFPUC either mounts pedestrian lights on existing streetlight poles or adds pedestrian-scale lights between existing streetlights.
Justification
Pedestrian lighting is a common request by the Board of Supervisors. Insufficient pedestrian lighting on the streets invites more crime, fuels a lack of security, and reduces livability for the general public at night. With improved pedestrian lighting, walking can become a more attractive option for people of all ages to utilize because of improved community safety. This project is consistent with SFPUC's technology policy by utilizing current lighting codes to improve streetlights' system reliability and economic value.

SFPUC’s Streetlight Pole Use Policy allows the use of streetlight poles by other City departments and nonprofit organizations such as neighborhood and community groups for festivity, decorative and holiday lighting purposes. SFPUC receives requests for such uses through an application process under the Streetlight Pole Use Policy. The HHP-Holiday and Festivity Pole Use project covers the cost of processing the special pole use requests, technical evaluation of engineering options, City staff labor, and the cost and purchase of necessary materials. In addition, the project will fund the cost of materials and additional resources to retrofit or modify street poles and brackets for this type of request.
Justification
There has been a tremendous increase of requests in the use of SFPUC poles since the Streetlight Pole Use Policy was adopted. This project is consistent with SFPUC's technology policy by utilizing current lighting codes to improve streetlights' system reliability and economic value.
Operating Impact
Failure to fund this project means that the SFPUC will be unable to add and maintain holiday lights and will have to scale back on holiday lighting.

The SFPUC owns and maintains approximately 25,500 streetlights in the City and County of San Francisco. Private telecommunication carriers would like to mount their 4G and 5G Distributed Antenna Systems (DAS) equipment on those poles to provide enhanced wireless services to customers in San Francisco. DAS equipment boosts mobile broadband coverage, improves reliability in heavily trafficked areas, and enhances network capacity. SFPUC supports DAS connections through program administration, engineering review, planning, design, construction management, construction, and maintenance. The Distributed Antenna Service projects fund SFPUC staff time to process carrier license applications, conduct engineering reviews including regular joint sessions with the carriers, track and manage dozens of simultaneous installation projects, conduct pre- and post-installation inspections, upgrade our infrastructure where required, connect carrier electric service, and process payment of administrative and license fees.
SFPUC recovers as much of the costs for administering the DAS program as is allowed under the 2018 Federal Communications Commission’s (“FCC”) 2018 small-cell order.
Justification
The FCC 2018 small-cell order sets firm deadlines for application approval, limits local fees to cost-based amounts, and preempts certain local rules slowing deployment. If SFPUC does not complete its review within those deadlines, the application may be deemed approved, which SFPUC must avoid to ensure safe and effective operation of our electric distribution system. The Distributed Antenna Services project enables SFPUC to monetize streetlight pole assets, process carrier applications, and recover reasonable review, construction, and maintenance costs from carriers, all while improving citywide wireless service.
Operating Impact
Wireless carriers pay a license administrative fee which covers the DAS approval process, a streetlight pole license fee, and a power connection fee. All these fees conform with the FCC’s cost-based standard.

The Energy Efficiency General Fund project supports advanced energy projects in the facilities of Power Enterprise's General Fund-rate customers.
Advanced energy projects include lighting, heating and ventilation, retro-commissioning, energy management systems, renewable, battery storage, and fuel switching. Energy Efficiency General Fund supports General Fund departments such as San Francisco Police Department, San Francisco Fire Department, San Francisco Unified School District, Real Estate Division, San Francisco Recreation and Parks, San Francisco Department of Public Health, and Fine Arts Museums of San Francisco. It funds SFPUC staff time to implement and assist with projects. Support includes planning, design and construction of advanced energy projects for "direct install", as well as technical assistance and project assistance for City departments with their own capital funds and those who do their own installation.
Justification
SFPUC receives project funding through the Cap & Trade Program which is administered by the California Air Resources Board and has been implemented as part of AB 32 (2006). All funds expended through the Cap & Trade Program are required to achieve greenhouse gas emissions reductions. These planned expenditures align with advanced energy investments and other local clean energy policies approved by the State, the SFPUC, and the City's Climate Action Plan. Providing advanced energy services also helps meet customer expectations for services and/or incentives.
Operating Impact
Advanced energy projects will provide carbon reductions and cost savings to City departments. Electricity saved will be available to offset power purchases and be available for resale.

Public Power Expansion funds financial, technical, regulatory, and legal analysis toward acquiring Pacific Gas & Electric Company's (PG&E) electrical assets; participating in critical litigation and regulatory proceedings; preparing to execute the possible transaction; and readying the SFPUC for operation of the acquired system.
Justification
This project furthers the City's effort to purchase the electric grid within San Francisco and achieve independence from PG&E. Expansion of the City's not-for-profit public power utility establishes local accountability for electric ratepayers in San Francisco; facilitates targeted investment in infrastructure to further transportation electrification, decarbonization and grid resiliency efforts; and allows for cost-effective provision of reliable, safe, and affordable electric service.
Additionally, acquisition of the electric distribution grid in San Francisco is necessary to ensure that the City can continue to provide electric service as envisioned in the Raker Act. PG&E has failed to provide adequate service under the Wholesale Distribution Tariff and continues to delay, obstruct, and deny the City's ability to interconnect customer load and distributed generation. PG&E’s on-going obstruction has cost the City tens of millions of dollars and delayed timely provision of City services to San Francisco residents.
Operating Impact
Public Power Expansion will ultimately allow SFPUC to manage ratepayer funds and direct investments to the local grid in a more cost-effective, timely and transparent manner. The SFPUC will be able to prioritize these investments to ensure a safe, reliable, and resilient grid, while moving the City towards meeting its climate goals and encouraging grid-dependent innovations. The public power business model is also superior to the for-profit investor owned utility model due to a lower tax burden, lower borrowing costs, and no shareholder profits.

This program will fund the development of new renewable energy (solar photovoltaic) and battery storage facilities on select SFPUC sites. The initial renewable energy facilities developed under this program would be structured as Power Purchase Agreements (PPA) with third parties that would develop and operate the facilities for an initial period of time. The PPAs would include a buy-out option for the City and the proposed program includes budget for the estimated acquisition cost of such facilities. The program is structured around six major phases, including: planning, Request for Proposals (RFP), construction and commissioning, PPA, asset management, and project buyout. The planning phase of the program will finalize the sites for bidding during the RFP Phase. The planning phase will also include a capital master plan for the renewable energy projects component, which will identify/propose the best path forward for structuring the ownership/financing and operation of the facilities.
Justification
Investment in local clean energy and the related generation of clean energy jobs was articulated as a goal by the SFPUC, Board of Supervisors, and Mayor when CleanPowerSF was authorized.
Operating Impact
The PPA phase of the program is projected to result in costs of approximately $1.5 million per year in FY 2028-2029. Starting in FY 2035-2036, SFPUC will be responsible for preventative and corrective operations & maintenance costs for the facilities under SFPUC ownership. These costs are estimated at approximately $600,000 per year. The timing of the impact of these expenses will depend on facilities development schedules and on-line dates to be finalized during the RFP phase. The timeline presented here represents the earliest possible on-line dates and cost impacts.

A significant part of the SFPUC’s Information Technology Services (ITS) infrastructure was implemented when headquarters moved to 525 Golden Gate Avenue in 2012. Much of the infrastructure implemented in 2012, which includes networking, telephony, conference room A/V equipment, etc., has surpassed its useful life. As a result, the likelihood of failure, not to mention cybersecurity risk, increases with the aging infrastructure. The purpose of this request is to fund the replacement, upgrade, and improvement of critical IT components/systems to mitigate these risks and provide higher levels of efficiency, reliability, and security.
Justification
Much of the current IT Infrastructure has surpassed its useful life. As a result, the likelihood of failure and cybersecurity risk, increases with the aging infrastructure. Upgrade, enhancement, or replacement of critical ITS Infrastructure components is needed to ensure uninterrupted, reliable, and secure technology resources are available to the entire organization.
Operating Impact
Improved Services that will be more reliable and secure.

Description
Through a collaborative effort, PUC HRS and ITS have been working together since last fiscal year with the goal of updating HRS’s critical IT infrastructure that has surpassed its useful life and at risk of failure. As a result of this collaborative effort, the Capital Plan request is for a Workforce and Talent Management System/ecosystem that fuels smarter decisions with data, enhances the user experience with efficiency and simplicity, and advances growth through integrated technology.
Justification
The expectations of human resources are evolving from service-oriented and operational focused to strategic partnership focused. To transform PUC HRS into a strategic partner, we must improve operational efficiency and increase strategic impact. The Workforce and Talent Management System is needed to replace fragmented, outdated existing HR IT infrastructure that limits accuracy, compliance, and the ability to manage a complex essential-services workforce. It will provide the modern tool and analytics required for an efficient, modern HR and a better employee experience, enabling the SFPUC to meet is core mission more reliably.
We are requesting funding for the purchase and implementation of a modern, cloud-based Workforce and Talent Management System platform. This system will replace HRS’s current ITS infrastructure that has surpassed its useful life and is at reach of failure in order to support the SFPUC’s most crucial resource: its people. This system will support efficient core HR functions, improve data accuracy, and align with departmental goals for digital transformation and operational excellence.
Operating Impact
This initiative aligns with our broader strategic goals of attracting and hiring great people, developing transformational leaders, fostering fulfilling careers, shaping a positive and safe employee experience, and cultivating strategic partnerships using people analytics to inform business objectives.
By addressing our HR systems needs comprehensively and strategically, we aim to enhance overall efficiency and drive organizational excellence. This approach reflects our commitment to making a well-informed investment in critical HR IT infrastructure, that will propel PUC forward in optimizing HR functionalities.
