CAISO Transmission Line from PG&E Newark Station to SVP Northern Receiving Station Project scope:
Two High Voltage Direct Current (HVDC) Terminals,
±320 kV HVDC underground and overhead transmission line between the terminals (preliminary preferred route is ~8 miles) 230 kV interconnection at each station
CAISO awarded to LS Power on March 7, 2023
Target in-service date by mid 2028
Coordination meetings with SVP currently underway
SVP Receiving Station Upgrades
Northern Receiving Station (NRS):
Relocation of two existing PG&E 115 kV overhead connections and CAISO meters, additional transformers, upgrade of existing main/transfer bus configurations, circuit breakers, disconnect switches and system protection improvements.
Stantec - 30% design is underway
Currently working on procurement for switches for Breaker 412 Mitigation Scott and Kifer Receiving Stations (SRS & KRS):
Full Rebuild - New 60kV/115kV Switchgear, control rooms, transformers, circuit breakers, disconnecting earthing switches, cable sealing, relocation of 60kV and 115kV transmission lines associated with each substation and removal of the existing substation at two sites.
TRC - 30% design is underway
Currently working on procurements for switchgear and control room enclosures KIFER

115kV Transmission Line
Northern to Kifer Receiving Stations
Project Scope: Construct a new 115kV transmission line between Northern Receiving Station and Kifer Receiving Station. The line will be designed to the higher 230 kV standards and energized at 115 kV.
Electrical Consultants, Inc. was selected as the design consultant and a Route Analysis Report has been prepared.
Verification of route feasibility will be performed by potholing for buried utilities prior to a final route recommendation.
Transformer Procurement for SVP Receiving Stations
Proposals received on May 2, 2023
Proposals are currently under evaluation/best and final offer (BAFO) for recommended selection Base quantity of two 240kV and nine 115kV transformers
Optional quantity is being considered. SVP has option to purchase future quantity based on this selection.
Request for award and purchasing approval will come to Council in Fall 2023 Procurement Lead Time average of 20 months with potential of 40+ months
Kifer Battery Energy Storage Project
Size:
Capacity up to 50MW/200MWh (4 hours daily)
Currently anticipating 45MW/180MWh of Guaranteed Capacity, with additional 5MW/20MWh of Excess Capacity Tesla Megapack technology
Estimated costs:
$4 million in Capital Costs
$7 M annually with 3.5% annual escalator for 20-year term Benefits:
Increased local area capacity for system reliability and flexibility Serves peak load
Increase use of renewable energy
Ability to perform intraday energy arbitrage
Qualifies for CAISO Resource Adequacy
Enhanced Resiliency
May reduce load shedding events during high stressed conditions on the grid.
Located on Raymond Street next to DVR Powerplant and new Kifer Receiving Station
Status:
PPA and Lease near completion (execution in August)
Final MND posted to City website
Draft Resolution near final, currently drafting RTC to request Council adoption (August) Interconnection Agreement near completion (requesting Council approval in August) Utility Location Survey and Topo Survey Completed

Solar Focus
Commercial & Multi-Family Solar Program
June 6, 2023, City Council Approved creation of a commercial solar rebate program in the Public Benefits Expenditure Plan Staff is in the process of creating a program, expected launch January 2024 Community Solar Survey Highlights – 171 Responses
Strong support of those surveyed support a community solar program – 75% Willingness to pay a small premium to lock in energy bill over time – 84% Right financial model will be crucial for program adoption Community Solar Next Steps
No in-house solar expertise, will need to contract
Request for Proposal for Feasibility Study and Business plan
Next 6 months highlights
Switchgear Procurement for KRS/SRS/NRS
Bond Financing of 4 CIP Transmission Projects ~ October/November to align with procurement of materials Completion of solicitations and master agreements for critical services supporting existing infrastructure (power plants, substations, transmission and distribution.)
