SGIP Rebates in 2026: What's Still Available and Who Qualifies

California's Self-Generation Incentive Program (SGIP) has been one of the most valuable battery storage incentives in the country since its expansion in 2017. As of 2026, SGIP funding remains available — but the program has evolved significantly, and not all customers qualify for the same rebate levels.

What SGIP Covers

SGIP provides upfront rebates for behind-the-meter battery storage systems — both residential and commercial. The rebate is calculated per kilowatt-hour of storage capacity and varies based on customer type, utility territory, and the specific SGIP budget step your application falls into.

The program is administered by California's four investor-owned utilities: SDG&E, PG&E, SCE, and SoCalGas. Each utility manages its own SGIP budget allocation, so availability and wait times vary by territory.

Who Gets the Highest Rebates

SGIP uses an equity-weighted structure that provides enhanced rebates to:

• Low-income residential customers (SGIP Equity Budget)
• Customers in high fire-threat districts (SGIP Equity Resiliency Budget)
• Critical facilities: hospitals, emergency services, water/wastewater
• Non-profit organizations serving low-income communities
• Customers who have experienced two or more Public Safety Power Shutoff events

Standard Commercial Rebates in 2026

For standard commercial customers, SGIP rebates in 2026 range from approximately $0.15 to $0.25 per watt-hour depending on the current budget step. For a 100 kWh commercial battery system, this translates to a rebate of $15,000–$25,000 — a meaningful reduction in the net cost of storage.

When combined with the 30% federal Investment Tax Credit (which applies to both the battery and installation costs), the effective net cost of a commercial battery system can be reduced by 40–50% from the gross installed price.

How to Apply

SGIP applications are submitted by the installing contractor on behalf of the customer. The application must be submitted before installation begins — retroactive applications are not accepted. Reservation of funds occurs at application; the rebate is paid after the system passes inspection.

An independent consultant can verify that your installer has correctly applied for SGIP, that the system meets program requirements, and that the rebate amount has been properly reflected in your project cost — not pocketed by the installer.
