The California Public Utilities Commission expanded the SGIP (Self-Generation Incentive Program) equity-tier rebate to 7 additional high-fire-risk counties in April 2026. Homeowners in these counties can now claim roughly 5× the state rebate vs the general tier, dropping the net cost of a Tesla Powerwall 3 to under $4,500 after combined federal + state incentives.
Newly eligible counties
The 7 counties added to the equity tier are:
- Nevada County (Grass Valley, Nevada City area)
- Plumas County (Quincy, Portola area)
- Sierra County (Loyalton, Downieville area)
- Yuba County (Marysville, Olivehurst area)
- Mariposa County (Mariposa, Yosemite area)
- Tuolumne County (Sonora, Twain Harte area)
- Calaveras County (San Andreas, Angels Camp area)
These counties join the existing equity-tier regions: much of the Sierra Nevada foothills, the North Coast, and the San Bernardino mountains. The full list of eligible zip codes is published on the CPUC SGIP portal.
What the equity tier pays
The SGIP equity tier pays up to $1.00 per watt-hour of installed battery capacity — significantly more than the general tier's $0.15–$0.35/Wh. For a Tesla Powerwall 3 (13.5 kWh = 13,500 Wh):
- General tier: $2,025–$4,725 rebate
- Equity tier: up to $13,500 rebate
Combined with the 30% federal Residential Clean Energy Credit (~$3,750 on a $12,500 install), equity-tier homeowners can install a Powerwall 3 for as little as $4,250 net. That's a 65% reduction from the typical net cost in non-equity-tier regions.
How to apply for SGIP
SGIP requires pre-approval before installation begins. The application process is:
- Verify your zip code is in the equity tier on the CPUC portal
- Get an installer quote and have the installer submit a reservation request through the SGIP application portal
- Wait for reservation approval (typically 4–8 weeks)
- Install the battery within 12 months of reservation approval
- Submit proof of installation and the rebate is paid within 60 days
Most installers handle the SGIP application for you, but you should explicitly ask your installer if they're filing the SGIP paperwork — some don't, and you'll lose the rebate if it's not filed.
Equity tier eligibility caveats
Equity tier eligibility is based on either:
- Geographic location — your home is in a high-fire-risk zip code (the newly expanded list above), OR
- Income qualification — household income at or below 80% of area median income (AMI), OR
- Tribal lands — home is on federally recognized tribal land
You only need to qualify under one of the three criteria. The geographic qualification is the easiest to document — your installer can verify your zip code in minutes.
Updated details in our cost guide
Our state rebate guide has been updated with the expanded equity-tier geography. California homeowners in the 7 newly eligible counties should consider this a strong signal to finally pull the trigger on a home battery — the math has never been better.
Pre-approval waitlists are currently 4–6 months. If you're on the fence, apply now — the equity tier budget is allocated on a first-come, first-served basis, and the program is funded through 2027 but could be exhausted before then if demand spikes.
