California's Self-Generation Incentive Program (SGIP) has distributed more battery storage rebates than any other program in the United States. At its peak, SGIP made home battery storage installations significantly more affordable — but the program has evolved dramatically, and as of early 2026, availability depends heavily on which tier you qualify for.
How SGIP Works
SGIP pays a cash incentive per kilowatt-hour (kWh) of battery storage capacity you install. It's administered by the California Public Utilities Commission (CPUC) and distributed through the investor-owned utilities — PG&E, Southern California Edison (SCE), and SDG&E. The rebate is paid in two installments: 50% upon installation and 50% after 12 months of operation.
Current Rebate Tiers and Amounts
SGIP uses a tiered structure based on customer eligibility:
- Equity Resiliency — up to $1,100/kWh: The highest tier. Available to customers in high fire-threat districts (HFTD Tier 2 or 3), those who have experienced two or more multi-day public safety power shutoffs (PSPS), medical baseline customers with life support equipment, and customers in DA/DACS disadvantaged communities who have experienced at least one PSPS event.
- Equity — approximately $850/kWh: For customers at or below 80% of Area Median Income, or residing in a CalEnviroScreen-identified disadvantaged community.
- General Market: The standard tier is currently waitlisted. The state-funded AB 209 Residential Solar and Storage Equity (RSSE) budget opened June 2, 2025 and exhausted available funds by December 31, 2025. New general market applications go to a waitlist.
Real Dollar Impact
To put these rates in context: a Tesla Powerwall 3 has 13.5 kWh of usable storage. An EcoFlow DELTA Pro Ultra starts at 6 kWh and scales to 90 kWh. At the Equity Resiliency rate:
- Tesla Powerwall 3 (13.5 kWh) → up to $14,850 in SGIP rebate
- EcoFlow DELTA Pro Ultra base (6 kWh) → up to $6,600
- Franklin WH (13.6 kWh) → up to $14,960
These are substantial amounts that can eliminate a significant portion of battery system cost even without the federal tax credit.
Do You Qualify for High-Tier SGIP?
Ask yourself these questions:
- Does your utility territory fall in a High Fire-Threat District (HFTD Tier 2 or 3)? This applies to much of foothill Orange County, the Inland Empire, and hillside/canyon communities in LA County.
- Has your power been shut off as part of a Public Safety Power Shutoff (PSPS) at least once in the last five years?
- Do you rely on medical equipment (oxygen concentrators, home dialysis, life support systems) that depends on electricity?
- Is your household income at or below 80% of your county's Area Median Income?
If you answered yes to any of these, you likely qualify for an equity tier with significant rebate amounts. Apply now — even waitlisted applications are served in order as funds become available from cancelled reservations.
How to Apply
SGIP applications must be submitted by a participating contractor — you cannot apply directly as a homeowner. Yealpha is registered with all three Southern California utilities for SGIP program participation. We handle the SGIP application as part of every qualifying battery storage installation, at no additional fee.
Combining SGIP with Other Incentives
SGIP can be combined with the SCE Charge Ready Home rebate (for EV charger + panel upgrades), utility TOU rate optimization, and California's NEM 3.0 net billing tariff for solar. It cannot be stacked with the federal 30% Residential Clean Energy Credit (which expired December 31, 2025) — but that credit no longer exists for new installations anyway.
