RECOMMENDATION(S):

APPROVE and AUTHORIZE Public Works Director, or designee, to execute the Battery Services Agreement and Savings Guarantee Agreement with TotalEnergies Distributed Generation USA, LLC for the installation, operation and maintenance of a Battery Energy Storage System at the West County Detention Facility, as recommended by the Sustainability Committee, Richmond area.

FISCAL IMPACT:

The net savings is expected to exceed $580,000 over a ten-year period (100% General Fund).

BACKGROUND:

On July 10, 2018, the Board of Supervisors approved the Distributed Energy Resources (DER) Plan, prepared by Public Works, and directed Public Works to issue a Request for Qualifications (RFQ) to select a partner to help the County with implementation of components of the DER Plan, Countywide. Through the RFQ process, Public Works selected SunPower Corporation (now TotalEnergies) to install PV systems under a Power Purchase Agreement in accordance with California Contracting Code 4217. Through the RFQ process, Public Works selected SunPower Corporation.

On June 18, 2019, the Board of Supervisors approved and authorized the Public Works Director, or designee, to execute ten Power Purchase Agreements with Solar Star Co Co 1 (SunPower Corporation) and three Battery Services Agreements for energy storage system services.

On March 31, 2020, the Board of Supervisors approved and authorized the Public Works Director, or designee, to execute a Letter of Intent (LOI) with SunPower Corporation Systems. The LOI allowed SunPower to submit applications to the California Energy Commission for Equity-Self Generation Implementation Program (E-SGIP) rebates to fund the installation of energy storage systems at County-owned facilities at no cost to the County.

SunPower Corporation (now TotalEnergies) secured a $1.8-million-dollar program incentive grant through the CPUC-funded Self-Generation Incentive Program (SGIP) for a battery storage system and EV chargers for the West County Detention Facility. Public Works is proposing to tie the proposed 449 Kilowatt battery storage system into the existing 900kW solar system on site and provide dedicated resiliency back-up power to new EV charging infrastructure to be included in project installation. This would allow the EV Chargers to provide up to 500 hours of vehicle charging in the event of electric grid outages. The program incentive would be signed over to TotalEnergies and will cover the cost of the battery storage system, EV chargers, and installation.

CONSEQUENCE OF NEGATIVE ACTION:

County will lose out on $600,000 in guaranteed electricity costs savings over a period of ten years. County will forego the opportunity to deploy (electric) grid-independent EV charging infrastructure, which would allow for EV charging during PG&E power outages.
