Helping Riverside County homeowners navigate SCE rates and solar options since 2020
Battery storage became significantly more important for California homeowners after NEM 3.0 took effect in April 2023. The Self-Generation Incentive Program (SGIP) is California's main rebate for home battery storage. But as of early 2026, the general residential SGIP budget is fully reserved and waitlisted. Here is what that means in practice.
1. What Is SGIP?
SGIP is the Self-Generation Incentive Program, administered by California utilities including SCE. It provides rebates for homeowners who install battery storage systems. The program has gone through multiple funding rounds since 2001 and remains one of the most substantial battery incentives available in the state when funded.
SGIP rebates are paid per kilowatt-hour of battery capacity. A 10 kWh battery system that qualifies for the equity category at $850 per kWh would receive an $8,500 rebate. That is a significant offset against battery costs of $12,000-$18,000 for a 10 kWh system.
2. SGIP Status in 2026
As of early 2026, the general residential SGIP budget administered through SCE and PG&E is fully reserved. Customers who apply now are placed on a waitlist. Budget availability depends on CPUC approving additional SGIP funding - which has happened in prior years but is not guaranteed on a specific timeline.
Getting on the waitlist now is still worthwhile. If CPUC authorizes additional SGIP funding, waitlist position matters. Contact SCE or an authorized SGIP installer to confirm your eligibility and get on the list if you qualify.
3. Equity and Equity Resilience Categories
The equity categories offer higher rebate rates for customers who qualify. They are designed to extend battery storage access to lower-income households and areas with specific grid reliability challenges.
Available to customers who meet income eligibility requirements or live in disadvantaged communities as defined by California's DAC mapping tool. For a 10 kWh battery at $850 per kWh, this category provides an $8,500 rebate when funded.
Higher rebate rate for customers in the equity category who also live in areas designated as being at elevated risk of PSPS (Public Safety Power Shutoff) events. Parts of Riverside County near high fire risk zones may qualify. For a 10 kWh battery, this provides a $10,000 rebate when funded.
Even waitlisted, equity category applicants should apply. If new SGIP funding is authorized, equity applications are typically prioritized over general market applications.
4. Battery Storage Economics Without SGIP
Even without the SGIP rebate, battery storage can improve solar economics for SCE customers on Time-of-Use (TOU) rate plans. The key is the peak/off-peak price differential.
A 10 kWh battery discharging fully during evening peak hours for 300 days per year provides approximately 3,000 kWh of peak hour displacement annually. At 50 cents per kWh avoided (the October-May mid-peak rate), that is $1,500 per year (3,000 x $0.50); at the 59 cent summer weekday on-peak rate it is $1,770 (3,000 x $0.59). Using the lower figure, that is approximately $1,500 per year in peak rate avoidance.
At $15,000 battery cost with no rebate, payback is approximately 10 years from TOU optimization alone ($15,000 / $1,500 = 10.0). If SCE rates continue rising at their historical 7% pace, the payback shortens as the peak rate climbs higher. For homeowners with strong AC load concentrated in evening hours, the math is compelling. For homeowners with modest bills or flexible usage timing, less so.
5. Battery Storage and Your Solar PPA
Many standard residential solar PPAs do not include battery storage by default. This is worth understanding clearly before you sign.
Under a typical solar-only PPA, you pay an example rate near 22 cents per kWh (ask your installer for your actual quoted rate) for solar-generated electricity. Without battery storage, excess solar generated during the day is exported to the grid at NEM 3.0 rates (5-6 cents/kWh). You then buy evening power from SCE at 59 cents per kWh on a TOU-D-4-9PM summer weekday (4pm-9pm), per SCE's rate page, checked October 7, 2026.
The PPA still saves you money - you are paying 22 cents for solar hours instead of 30 to 39 cents (Tier 1 and Tier 2 on SCE's tiered plan) for those same hours from SCE. But a battery would optimize those savings further by capturing midday solar and discharging it during evening peak hours.
Ask whether battery storage can be added to a PPA agreement, and if so, under what terms. Some PPA providers offer battery add-ons through separate agreements or as part of enhanced packages. Get the specific terms in writing before committing.

Frequently Asked Questions
The general residential SGIP budget is fully reserved as of early 2026. New applicants are placed on a waitlist. The equity and equity resilience categories are also waitlisted but are prioritized if additional SGIP funding is authorized by the CPUC. Getting on the waitlist is still worth doing if you plan to add battery storage.
SGIP rebate rates vary by category. The general market rate is $200 per kWh. The equity category offers $850 per kWh, and the equity resilience category offers $1,000 per kWh. For a 10 kWh battery, equity customers could receive $8,500-$10,000 in rebates when the program is funded.
SGIP equity eligibility is based on income qualification or residence in a California-designated disadvantaged community (DAC). Customers enrolled in utility low-income programs like CARE or FERA may also qualify. The equity resilience tier additionally requires living in an area with elevated PSPS risk.
For SCE customers on TOU rate plans with significant evening peak consumption, battery storage can still be financially viable without the SGIP rebate. The payback period is longer (approximately 10 years at current rates vs. 6-8 years with SGIP), but rising SCE peak rates accelerate that math over time.
