County staff outlines energy program targets; seeks evaluation of battery storage and EV charging

Summary
General Services presented a progress report and plan for county energy projects, including nine solar agreements, 150 planned EV chargers (state grant), LED retrofits and a conceptual battery‑storage pilot. Staff projected long‑term savings and asked the board for direction on exploring battery sites and financing options.
General Services presented an update to the Board of Supervisors on Jan. 13 outlining current energy projects, near‑term investments and potential battery‑storage pilots.
The division summarized four priority areas — fiscal responsibility, environmental sustainability, resilience and staff health — and highlighted recent achievements: nine solar purchase agreements, 11 LED retrofit projects, operation of a 250‑kilowatt solar array and a building energy management system. The presenter said those initiatives could yield substantial savings over time and cited a projection: “we are projecting that we will save $50,000,000 over 30 years” from the identified solar agreements.
Staff described plans to install roughly 150 EV chargers (using a California Energy Commission grant), target battery‑storage pilots (including conceptual siting at Tajiguas) and continue net‑zero and retrofit work at county facilities. Presenters said energy costs remain volatile and that shifting to renewables and storage can both reduce long‑term operating costs and provide resilience for critical services in disasters.
Board questions focused on scale, funding and tradeoffs. Supervisors asked whether the county should use general‑fund capital dollars or pursue grant/third‑party finance, how employee health benefits would be tracked in energy projects and how battery storage would be sited and evaluated. The presenter said staff was in a conceptual phase on storage and would prepare an evaluation of costs, benefits and siting; he also described an annual cleaning/maintenance program for solar assets.
Board action and next steps: Supervisors directed staff to evaluate battery‑storage options, continue coordination with other county departments on EV‑charger siting and return with more detailed cost‑benefit and financing proposals. The board did not appropriate capital funds at the meeting but endorsed pursuing grant and partnership opportunities and integrating energy projects into the county's capital plan.
What to watch: Staff will return with a more detailed analysis of battery siting, projected capital needs and proposed funding approaches; supervisors asked for specific metrics on cost savings and resilience benefits.
