How does the California Rate Relief Program work?

We install solar panels on your roof at no cost out of pocket. Instead of paying your utility company a different amount every month, you pay a fixed monthly payment that is typically 30 to 50% less than what you are currently paying. The program covers 100% of the cost for solar panels, backup batteries, and installation.

Who qualifies for the Rate Relief Program?

California homeowners with SCE, PG&E, or SDG&E as their utility provider, monthly electric bills of $150 or more, and a credit score of 650 or above typically qualify. Renters are not eligible for this program.

Is there any cost to the homeowner?

There is $0 out of pocket cost. The program covers the full cost of solar panels, battery storage, and professional installation. Instead of paying your utility company, you simply pay a lower, fixed rate for the power generated by the system on your roof.

What happens if something breaks?

The program includes a comprehensive 25-year bumper-to-bumper warranty. If a panel breaks, it gets fixed. If an inverter fails, it gets replaced. All maintenance and repairs are covered at no cost to you for 25 years.

Which utility companies are supported?

The program currently supports homeowners with Southern California Edison (SCE), Pacific Gas & Electric (PG&E), San Diego Gas & Electric (SDG&E), Moreno Valley Utility (MVU), and Los Angeles Department of Water and Power (LADWP).

SGIP Commercial Battery Storage Rebates California 2026

California's Self-Generation Incentive Program (SGIP) provides rebates for behind-the-meter battery storage — including commercial battery systems paired with solar. The program has been a major driver of commercial battery economics in California over the past decade, but 2025-2026 is a transition period: the Large-Scale Storage budget closed to new applications after December 30, 2025, several general-market budgets are waitlisted, and remaining funds are stepping down as incentive levels decrease.

How SGIP Commercial Rebates Work

SGIP is administered by California's investor-owned utilities (PG&E, SCE, SDG&E, SoCalGas) under CPUC oversight. The program offers per-kWh rebates for qualifying battery storage installed behind the meter at customer sites. The rebate amount varies by:

•Budget category: General Market, Equity, Equity Resiliency, Large-Scale
•Step level: Incentive rates decline over time as each budget fills (stepped down)
•Customer class: Residential, small commercial, large commercial, non-profit
•Resilience eligibility: High-fire-risk area, medical baseline customer, etc.

2025 rebate rates stepped down to approximately $0.15-$1.00 per kWh of storage capacity depending on the specific budget, step, and equity/resilience qualifications. Higher rates apply to equity-resilience customers; lower rates to general-market large commercial.

Current Budget Status (as of early 2026)

Large-Scale Storage budget: Closed to new applications after December 30, 2025. Projects that applied before the deadline are still in queue for funding.

General Market commercial budget: Continues in 2026. Many utility-specific budgets are waitlisted as demand outpaces available funding. Application to approval can take 3-9 months depending on waitlist position.

Equity and Equity Resiliency budgets: Continue with prioritized funding. Target low-income communities, disadvantaged communities, high-fire-risk areas, and medical baseline customers. Rates are typically significantly higher than General Market.

Check current budget availability with your utility's SGIP webpage and the CPUC's program handbook before finalizing your project pro-forma. Budget availability changes frequently as applications are processed.

SGIP + Federal ITC Stack

The California SGIP rebate stacks on top of the federal 30% Investment Tax Credit. For a commercial battery install, the effective cost math works roughly like:

Gross installed cost. E.g., $400/kWh × 200 kWh = $80,000
Less SGIP rebate. E.g., $0.30/kWh × 200 kWh = $60,000 rebate (directional — varies by step/budget) — net $20,000
Less 30% ITC. Applied to gross cost before SGIP per current IRS guidance (verify with your tax advisor): $24,000 credit
Less MACRS depreciation tax shield. Applied to gross cost less half the ITC per standard IRS rules
Effective after-tax cost: often approaching zero or negative on smaller commercial systems when SGIP is at its high-tier rates

The specific numbers depend on your exact SGIP budget category, current step rate, tax rate, and system size. Your commercial EPC and tax advisor should run the actual pro-forma.

How to Apply for SGIP

Commercial SGIP applications go through your utility's SGIP program administrator (PG&E, SCE, SDG&E, SoCalGas). Your battery installer or commercial solar EPC typically handles the paperwork. Key timing:

Submit the SGIP reservation application with project specs and equipment details
Utility reviews and reserves the rebate amount (days to weeks depending on queue)
Install the battery system per the reserved specifications
Submit post-installation documentation (interconnection approval, system commissioning)
Receive rebate payment (usually within 30-90 days of post-install approval)

Frequently Asked Questions

Is SGIP still available for commercial in 2026?

The General Market and Equity budgets continue in 2026 but many are waitlisted. The Large-Scale Storage budget closed to new applications after December 30, 2025. Verify availability with your utility before counting on the rebate.

How much is the SGIP rebate for commercial battery storage?

Approximately $0.15-$1.00 per kWh of installed storage capacity depending on budget, step, and equity qualifications. Equity-Resilience customers in high-fire-risk areas see the highest rates. Standard General Market commercial is at the lower end.

Can SGIP stack with the federal ITC?

Yes. SGIP and the 30% federal Investment Tax Credit stack. Combined, they can reduce commercial battery cost by 50-80% on some projects. Verify the specific stacking rules with your tax advisor since state rebates can reduce the ITC-eligible basis in some cases.

What happens when SGIP budgets run out?

The CPUC typically steps down rates as budgets fill and opens new budget allocations periodically. When a specific budget runs out, projects that applied are either waitlisted for the next allocation or move to a different budget if eligible. Historically the program has been re-funded multiple times; long-term availability is not guaranteed.
