FROM: Greg Hermann, Deputy City Manager
Prepared By: Lucia Pohlman, Sustainability and Natural Resources Analyst SUBJECT: DEPLOYMENT OF PUBLIC ELECTRIC VEHICLE CHARGING

INFRASTRUCTURE ON CITY PROPERTY

RECOMMENDATION

1. Authorize the City Manager to enter into an Agreement with ChargePoint to develop the project scope, conduct site assessments, and prepare design packages in order to develop no-cost deployment of public electric vehicle chargers and related infrastructure on City Property, in a form satisfactory to the City Attorney; and

2. Direct staff to negotiate terms for a no-cost lease or license agreement with the City’s chosen owner and operator for ChargePoint electric vehicle charging infrastructure; and

3. Authorize the City Manager to enter into a no-cost lease or license agreement with the City’s chosen owner and operator of ChargePoint electric vehicle charging infrastructure, in a form satisfactory to the City Attorney.

POLICY CONTEXT
Resolution 11159 (2020 Series), includes the goal of carbon neutrality by 2035 and a transportation sector goal for electric vehicles to account for 40 percent of vehicle miles traveled by 2030. Deploying public electric vehicle (EV) chargers supports the City’s mode split objective.

Deploying public EV charging stations is connected to two of the City’s Major City Goals for 2021-2022:
 Climate Action, Open Space & Sustainable Transportation – Deploying publicfacing EV chargers supports drivers in transitioning from fossil-fueled powered mobility options to electric alternatives powered by Central Coast Community Energy’s renewable energy generation facilities.
 Diversity, Equity, and Inclusion – While owning an electric vehicle can provide substantial savings on fuel, many community members face obstacles to installing a charger at their residence, especially renters and low-income and multi-family housing residents. Staff’s recommendation would result in additional publicly available electric vehicle charging infrastructure, which would enable more community members to own an electric vehicle.

Item 6h

DISCUSSION
The discussion section of this report provides historical background and the demonstrated need for public EV charging infrastructure, including an overview of the City’s climate action goals and a summary of the preferred vendor selection process.

Background
Climate Action Plan for Community Recovery
On August 19, 2020, City Council approved the Climate Action Plan for Community Recovery (CAP), and adopted Resolution 11159 (2020 Series), which set the goal of carbon neutrality by 2035 and a transportation sector goal for electric vehicles to account for 40 percent of vehicle miles traveled by 2030. The CAP forecasts annual community emissions to be approximately 397,710 metric tons of carbon dioxide equivalent (MTCO2e) in 2035. The plan provides a trajectory to reducing these emissions towards net zero by 2035, with approximately sixteen percent of total reductions coming from achieving the transportation sector goal (64,170 MTCO2e). Of that, a projected 34,920 MTCO2e in reductions are expected to come from the rapid uptake of EVs, the largest single reduction area in the plan.

Emerging Considerations
Since adoption of the CAP, several key variables have changed, including:

1. Fuel Prices – According to AAA, San Luis Obispo County’s average gallon of gas was $6.53 as of June 27, 2022,
1 which is a sixty percent increase from the average
rate of $4.09 in April of 2021.

2. EV Adoption – In just five years, EVs as a percentage of total light duty vehicles in California went from 4.29% (2017) to 12.41% (2021).2

3. Existing Chargers – According to the comprehensive charger database maintained by PlugShare, there are 134 publicly available charging stations in San Luis Obispo.

Of these stations, 54 are fast chargers for Tesla drivers only, and three are open access fast chargers. The remaining 77 are level 2 chargers (including all the chargers provided by the City).3

4. Charger Utilization – As described below, the Marsh Street Parking Garage chargers are the only publicly available charging resources on City land. The Marsh Street garage chargers have seen steady and continual growth in use since 2020. Estimates are that EV charging demand will be 10 times today’s public charging use by 2030.

https://www.plugshare.com/directory/us/california/san-luis-obispo. 4 Engel et al., “Charging Ahead: Electric-Vehicle Infrastructure Demand”

Item 6h

5. Charger Availability – A large barrier to adoption is the public’s perception of EVs and range anxiety, a term used to describe the fear of being stranded on the side of the road with no chargers nearby. This phenomenon is the main reason why so much focus is being placed on EV charging infrastructure. A strong, accessible, and visible EV network will provide user confidence and induce EV ownership.

Given these key changes, along with the urgent need to reduce greenhouse gas emissions,5 staff is pursuing a streamlined and expedited approach to deploy public EV charging at no cost to the City.

Approach for No-Cost Deployment of Public EV Charging Infrastructure on City Property Staff is pursing no-cost deployment of direct current fast charging (DCFC) and Level 2 chargers at strategic locations by leasing City parking spaces to a qualified vendor for the purpose of constructing, owning, and operating the charging assets for a defined term.

Through a competitive bidding process initiated with a Request for Proposals (RFP) on May 6 through June 14, 2022, the City received three proposals from interested vendors. The RFP required that the project come at no cost to the City. The RFP (provided as Attachment A) mirrored successful efforts underway by peer cities6 and included the following scoped tasks:

1. Identify strategic locations at which to deploy EV charging stations.

2. Achieve completed installations at each EV Charging Site including permits, site preparation, and charger installation. Chargers shall have minimum requirements associated with performance, accessibility, interoperability, etc.

3. Operate, maintain, and provide customer service support for the chargers for a set term. This will include provisions for pricing, data sharing, and marketing.

4. Decommission the unit or transfer ownership to the City at the end of the term.

In the interest of supporting the site identification task, staff identified three locations as potential sites for new DCFC charging station deployment, while allowing vendors to identify and propose additional sites for evaluation:
 Lot 9: 680 Monterey St., San Luis Obispo, CA 93401
 Calle Joaquin Park & Ride Lot: 1530 Calle Joaquin, San Luis Obispo, CA 93405  Santa Rosa Park Lot: 1050 Oak St., San Luis Obispo, CA 93405 Preferred Vendor Selection
An RFP committee comprised of City staff from the Office of Sustainability and Natural Resources and Public Works Parking Division reviewed proposals from Blink, Carbon Solutions Group, and ChargePoint. The committee unanimously selected ChargePoint as the preferred vendor based on the evaluation criteria included in the RFP, as well as additional information gained through reference checks and informal interviews with bidders.

https://destinyhosted.com/palmsdocs/2021/CC/20210211_1285/2841_5C_OCR.pdf

Item 6h
The full ChargePoint proposal is included as Attachment B. Key points of the proposal include:
 Identification of three initial locations for deployment – Lot 9, Calle Joaquin Park and Ride Lot, and Santa Rosa Park Lot – as well as transferring operations and maintenance of the City’s existing ChargePoint assets, future chargers in the Palm Nipomo parking garage, and possible fleet work given City approval  A total of 14 DCFC ports with 62.5kW capacity, and six Level 2 ports  An open-source network solution
 Proposal value of $2,275,000
 5-year contract term length
ChargePoint’s proposal lays out a project plan that begins with developing the project scope, conducting site assessments, and preparing design packages. ChargePoint will then bring the opportunity for owning and operating ChargePoint’s charging infrastructure to its partners as a package. Through a ChargePoint managed process, the City will select the owner and operator partner that will implement ChargePoint’s proposal. The partner will be selected based on parameters including maintenance response time, providing any additional investment in infrastructure in lieu of lease payments, and successful previous experience. The City will then enter into a no-cost lease or license agreement with the chosen partner. Staff is confident that this flexibility will enable the City to choose the best owner and operator and negotiate final terms that are most advantageous to the City, while also maintaining an accelerated project timeline and building on the ChargePoint brand San Luis Obispo community members are most familiar with.

Previous Council or Advisory Body Action
The topic of electric mobility was presented to City Council on August 18, 2020, when the Council adopted the Climate Action Plan for Community Recovery, which includes the goal of carbon neutrality by 2035 and a transportation sector goal for electric vehicles to account for 40 percent of vehicle miles traveled by 2030.

In response to gas price increases and rapid uptake of electric vehicles, City staff presented a closed session item to City Council on May 3, 2022, to receive lease parameters to include in an RFP for no-cost deployment of public electric vehicle (EV) charging infrastructure. The RFP is provided as Attachment A and is consistent with these parameters.

Public Engagement
Staff conducted public engagement on the topic of electric mobility in the Spring of 2022.

This effort included the Connected Community Strategy Forum, which gathered on March 9, April 7, and May 10, 2022, to solicit feedback from community leaders and technical experts on the development of an electric mobility plan, as well as other strategies to reduce transportation-related GHG emissions. The group was led by staff from the Office of Sustainability and Natural Resources and the Public Works department and was comprised of stakeholders from Bike SLO County, the Lumina Alliance, the Chamber of Commerce, the Mass Transportation Committee, the Active Transportation Committee, Cal Poly student body, YIMBY, RideOn, and SLOCOG.

Item 6h
The strategy forum aligned around a recommendation to “support publicly accessible electric vehicle chargers on City property.”

CONCURRENCE
The Public Works Parking Division concurs on the contents of this report.

ENVIRONMENTAL REVIEW
The California Environmental Quality Act does not apply to the recommended action in this report, because the action does not constitute a “Project” under CEQA Guidelines Section 15378.

While there is no direct cost to the City, significant staff time will be dedicated to ensure the successful deployment of EV charging infrastructure. This will primarily be supported by the contract analyst position in the City’s Office of Sustainability and Natural Resources; a position that is fully funded in the approved Administration and IT budget.

Avoided Costs
ChargePoint has proposed a zero-dollar lease model that will result in no costs to the City for the deployment of public EV charging infrastructure at three locations on City property.

This approach enables the City to deploy chargers at financially viable locations with no City capital outlay. ChargePoint and the selected partner would pay for all installation and equipment costs associated with the EV chargers and related infrastructure costs (estimated at approximately $2,275,000 across three sites). In addition to the infrastructure and equipment costs, the City will also avoid the maintenance and networking fees associated with the EV charging stations. ChargePoint has also offered to provide ongoing operational support for the City’s existing public EV chargers, as well as current and forthcoming fleet chargers, however the value of this offer is not yet known.

No additional budget or operational changes are requested as part of this proposal.

Item 6h

NEXT STEPS
Pending direction from City Council, the City Manager would execute an agreement with ChargePoint to develop project scope, conduct site assessments, and prepare design packages for public electric vehicle chargers and related infrastructure. Staff will work with ChargePoint to select the owner and operator of the charging infrastructure best aligned with the parameters set forth by prior Council direction. The City Manager will execute a lease or license agreement with the chosen owner and operator, to the satisfaction of the City Attorney. ChargePoint’s proposal outlines a project schedule wherein project completion is anticipated in 2023.

ALTERNATIVES

1. Council could request additional information prior to taking action, although the process outlined in this Council Agenda Report is consistent with prior Council direction.

2. Council could direct staff to not select a qualified vendor from this RFP process and not pursue public charging on City property until the 2023-25 Financial Plan, or identify other budget resources to directly install, own, and operate chargers. Staff does not recommend this approach as it would require substantial capital and staff time that is not currently programmed.

3. Council could direct staff to return to Council for approval of the lease or license agreement with City’s chosen owner and operator of ChargePoint’s electric vehicle charging infrastructure. Staff does not think this approach is necessary given specific prior direction from Council on the desired parameters of an agreement for third-party owned and operated public EV charging infrastructure, and due to the City’s desire for timely delivery on this item.

A. INTRODUCTION
On August 19, 2020, Council approved the City’s Climate Action Plan for Community Recovery, and adopted Resolution 11159 (2020 Series), which includes the goal of carbon neutrality by 2035 and a transportation sector goal to achieve the General Plan mode split objective by 2030 and 40 percent of vehicle miles traveled by electric vehicle by 2030.

The Climate Action Plan for Community Recovery forecasts annual community emissions to be approximately 397,710 metric tons of carbon dioxide equivalent (MTCO2e) in 2035. The plan provides a trajectory to reducing these emissions towards net zero by 2035, with approximately sixteen percent of total reductions coming from achieving the transportation sector goal (64,170 MTCO2e). Of that, a projected 34,920 MTCO2e in reductions are expected to come from the rapid uptake of electric vehicles, the largest single reduction area in the plan.

According to the comprehensive charger database maintained by PlugShare, there are 134 publicly available charging stations in San Luis Obispo. Of these stations, 54 are fast chargers for Tesla vehicles only, and 3 are open access fast chargers. The remaining 77 are level 2 chargers (including all chargers provided by the City). Since adoption of the Climate Action Plan, several key variables have changed that have made the need for additional EV charging infrastructure even more important, including:

1. Fuel Prices - According to AAA, San Luis Obispo County’s average gallon of gas was $6.01 as of April 5, 2022, which is a 46 percent increase from the average rate of $4.09 in April of 2021.

2. EV Adoption – In just five years, EV’s as a percentage of total light duty vehicles in California went from 4.29% (2017) to 12.41% (2021). In San Luis Obispo County, there has been an increase of over 70% between 2020 and 2021.

3. Charger Utilization – As described below, the Marsh Street Parking Garage chargers are the only publicly available charging resources on City land. The Marsh Street garage chargers have seen steady and continual growth in use since 2020.

Given these key changes, along with the urgent need to reduce greenhouse gas emissions, the City is seeking a streamlined and expedited approach to deploy public electric vehicle charging.

B. SCOPE OF WORK
The City seeks proposals from qualified vendors that can install, operate, and maintain open-source public DC Fast Charging (DCFC) and Level 2 Charging Stations, as feasible, on City-owned properties and in public rights of way.

Proposers may identify only DCFC chargers, only Level 2 chargers, or both. The selected vendor will be responsible for and cover all costs associated with the procurement, installation, operation, and maintenance of new charging stations on City-owned properties. If a proposing vendor believes that the intent of the project can be achieved through an alternative scope of work, the City will accept their proposal for review so long as the amendments to the proposed scope of work contained herein are adequately justified.

Task 1. Site Identification
The City is interested in deploying the maximum number of DCFC and Level 2 chargers as rapidly as possible.

Respondents will identify and propose strategic locations at which to deploy charging stations. In the interest of supporting the assessment, the City has identified three locations as potential sites for new DCFC charging station deployment and defers to proposers on these sites’ viability and the inclusion of additional sites:
▪ Lot 9: 680 Monterey St., San Luis Obispo, CA 93401
▪ Calle Joaquin Park & Ride Lot: 1530 Calle Joaquin, San Luis Obispo, CA 93405 ▪ Santa Rosa Park Lot: 1050 Oak St., San Luis Obispo, CA 93405

-2-
Please note that these sites are only provided to support the assessment and any public parking lot, parking space or garage is eligible for consideration.

Task 1 will include the submittal of a concept-level map identifying initial proposed locations, or priority areas, for proposed installations. This map should be accompanied by a brief summary of methods and/or key criteria that informed site selection, such as adjacent uses, land use densities, or considerations based on the proposed service model. Overall, the City wishes to maximize the number of new charging stations installed at strategic locations.

Final site selection for charging infrastructure deployment is subject to approval by the City.

Task 2. Installation
Upon final site selection, the selected vendor is responsible for achieving completed installations at each charging station, to include:
▪ Obtaining all applicable local, state, and federal permits required for installation and operation of the charging stations.
▪ Ensuring that all installation work as it pertains to site preparation, curbing, striping, signage, charging equipment, billing and networking systems, and electrical interconnections is working properly and installed:
o consistent with the manufacturers’ specifications
o consistent with the project design proposed in the bid o in accordance with all applicable local, state, and federal zoning and code requirements ▪ Coordinating the installation activities with the equipment manufacturer, City staff, networking service, electric utility, and any subcontractors needed to complete the work.

Task 3. Operations and Maintenance
The selected vendor will:
▪ Operate and maintain each charging station for at least five (5) years from the date the charging station developed under this RFP becomes operational, in accordance with the terms of the contract resulting from this RFP. Bidders may include proposals for a longer term. Term proposals should also include details about asset decommissioning and/or right to transfer ownership at the conclusion of the term. ▪ Be responsible for ensuring the maintenance of the chargers including cables, ancillary equipment, and any awnings, canopies, shelters and information display kiosks for signage associated with the charger. “Maintain” as used in this RFP shall mean, “to provide all needed repairs or desired and approved alteration, as well as regular maintenance needed to ensure optimal performance and minimize downtime. Equipment shall be kept safe and presentable.”
▪ Ensure that the equipment at each EV Charger is operational with uptimes consistent with industry standard best practices. It is the Contractor’s responsibility to ensure the uptime commitments are met for each individual charger and that interruptions are remedied within a pre-arranged and agreed upon time frame. ▪ Not, during the period of operation, move a charging station, sell or take a charging station out of service for any reason, without prior written approval from the City.

Task 4. Monitoring
Each charging station should have network communications that, at a minimum, provide the following information about each charging transaction, at each charging location:
▪ Charging data such as date and time of usage (start and stop time) and accurate utilization rates. o Total kWh and Total kW draw.
o Total dollar amount charged to the user.
o Station status and health in real time.
o Malfunction or operating error.
▪ The selected vendor shall report full site level usage quarterly to the City for the duration of the contract.

Task 5. Customer Support Services
Provide customer service support as follows:
▪ Provide customer support for the duration of the contract, with the ability to provide customer support/or extend after the completion of the contract.
▪ Resolve customer issues over the telephone.

C. PROJECT SCHEDULE
Successful respondent(s) should demonstrate their ability to rapidly deploy charging infrastructure as described in this RFP. Respondents should include a proposed timeline that includes the most rapid deployment feasible, describe how it has the capacity to meet this timeline, and identify any potential obstacles to the achieving the timeline along with proposed approaches to mitigate these obstacles.

D. PROJECT BUDGET
This RFP solicits services at no cost to the City. Proposals should include an estimated project budget that allows the City to evaluate the cost-effectiveness and long-term financial viability of proposed services. Projects with selfsustaining business models are highly preferred. Proposals should include lease payment amounts or a “no cost” lease where the vendor uses the lease savings to install level 2 charging units at other locations in the City (note that the installation of additional units is the City’s preferred approach). Proposals should clearly identify the proposed lease amount per space per year and/or propose an alternative approach to provide value for the leased space.
