Self-Generation Incentive Program (SGIP) — Battery Storage co-located with EV Chargers
Self-Generation Incentive Program: per-kWh battery storage rebate. Equity tier (DAC/<80% AMI) up to $850/kWh. Storage adjacent to chargers.
How it pays
Per-kWh storage rebate. General Market: ~$150/kWh. Equity (DAC/LIC <80% AMI): up to $850/kWh. Residential Solar+Storage Equity (RSSE): up to $1,100/kWh storage + $3,100/kW solar. SGIP funds STORAGE — not chargers — but storage paired with chargers reduces grid impact and is a critical co-located capex.
DAC bonus available. Projects in state-designated low-income or environmental-justice areas qualify for a higher rebate amount on this program.
Who qualifies
EV chargers themselves NOT eligible. BESS sized to support charger demand-shifting/peak shaving IS eligible. Track record of pairing SGIP storage with DCFC sites to manage demand charges.

How this stacks with other programs
California State programs typically stack with utility, regional (air district), state, and city/county programs on the same project. The general California stacking rules:
- Federal §30C tax credit: stacks with state, utility, regional, and local cash rebates without offset. Stacks with federal grants only with basis offset (federal grant amount reduces §30C basis).
- Federal grants (CFI, REAP, NEVI): not stackable with other federal grants on the same port.
- State + utility + regional + local: generally full stack across tiers. Same-tier programs serving the same port don't double-fund.
For the full stacking matrix, see the homepage stacking section.
