Last updated: March 2026Peninsula Clean Energy / PG&E

No Local CCA Battery Program Yet

San Mateo County doesn't currently offer a dedicated local battery rebate through its community choice aggregator. However, residents can still access substantial federal and state incentives worth up to $17,500 for qualifying households.

Available Incentives for San Mateo Residents

Federal Investment Tax Credit (ITC)

30% of Cost

The Inflation Reduction Act of 2022 extended the federal clean energy tax credit at 30% through 2032.[1]

For a typical 13.5 kWh battery system costing $12,000-15,000, the ITC provides $3,600-$4,500 in tax credits. For leased systems, the leasing company claims the credit and passes savings to you through reduced monthly payments.

California Self-Generation Incentive Program (SGIP)

$200-$1,000/kWh

California's SGIP is one of the nation's longest-running distributed energy incentive programs, administered by the California Public Utilities Commission.[2][3]

Standard residential rebate: ~$200/kWh ($2,700 for 13.5 kWh battery). Equity Resiliency rebate for income-qualified households or those in high fire-threat areas: up to $1,000/kWh ($13,500 for 13.5 kWh battery).

Why Battery Storage Makes Sense in San Mateo

NEM 3.0 Changes Everything

California's new Net Energy Metering rules (NEM 3.0) reduce the value of exported solar by 75%. Batteries are now essential to maximize your solar investment by storing energy for self-use rather than exporting at low rates.[5]

Time-of-Use Rate Arbitrage

$500-1,200/year

California utilities charge significantly more during peak hours (4-9 PM) than during midday solar hours.[4]

With Peninsula Clean Energy / PG&E, peak rates can exceed $0.45-0.55/kWh while off-peak rates are $0.15-0.25/kWh. A battery lets you store cheap midday solar and use it during expensive peak hours, saving $40-100/month.

Backup Power & PSPS Protection

California's Public Safety Power Shutoffs (PSPS) can leave homes without power for days during fire season. A battery keeps critical loads running.[5]
