If you have a home battery in California, or you're about to install one, there's a rebate program that can put thousands of dollars back in your pocket. It's been around for years, the utilities administer it, and a lot of homeowners assume it's already tapped out.
As of October 2026, they're mostly right. Nearly every SGIP budget is closed. One isn't, and if your household qualifies for it, it's the biggest battery incentive left in California.
What Is the Self-Generation Incentive Program (SGIP)?
The Self-Generation Incentive Program is a California Public Utilities Commission (CPUC) initiative that pays homeowners a per-kilowatt-hour rebate for installing qualifying energy storage systems. It launched in 2001, originally funding small generators and fuel cells. Over time it shifted heavily toward battery storage, and today it's essentially a solar-plus-storage and standalone battery incentive program.
Your utility (PG&E, SCE, or SDG&E) handles reservations, applications, and payments. The CPUC sets the rules and allocates the budgets.
The underlying motivation is grid resiliency. California wants more distributed storage to reduce peak demand strain, especially during wildfire season when the grid is most stressed. The program funds that transition by subsidizing residential batteries.
What's Open and What's Closed
SGIP pays in steps: each budget has a rate that drops as money gets reserved, and when a budget runs out it closes or moves to a waitlist. Here's where the residential budgets stood on the SGIP step tracker on October 12, 2026:
| Budget | Who it was for | Rate at last step | Status |
|---|---|---|---|
| Small Residential Storage | Any residential customer | $150/kWh | Closed |
| Equity Resiliency | High fire-threat districts or a PSPS history | $1,000/kWh | Closed |
| Residential Solar and Storage Equity (ratepayer-funded) | Income-qualified households | $1,100/kWh | Closed |
| Residential Solar and Storage Equity (AB 209) | Income-qualified households installing new solar and storage | $1,100/kWh storage + $3.10/W solar | Open for customers of municipal utilities in PG&E and SCE territory; waitlist everywhere else |
So if you were hoping for the standard $150/kWh on a Powerwall for an ordinary install, that money is gone. Budgets do change, so check the tracker before you rule it out, but don't build a quote around it.
Who Still Qualifies
The AB 209 equity budget is the one to look at. It's aimed at low-income households: at or below 80% of area median income, or enrolled in CARE, FERA or ESA. It pays for new solar and storage installed together, not a battery added to an existing system.
At the current step, a 13.5 kWh battery works out to about $14,850, and a 6 kW solar array adds roughly $18,600. For a qualifying household that can cover most or all of the project.
Most of the budget is on a waitlist. The open slice is for customers of municipal (publicly owned) utilities located inside PG&E or SCE territory. Getting onto the waitlist still matters: when funds free up, applications move in order.
One requirement has applied to every residential tier: you enroll in a qualifying Demand Response program, which commits your battery to respond to grid events. Which programs qualify has changed from cycle to cycle, so pin this down with your installer before you sign.
How to Apply for the SGIP Rebate
The application doesn't go through you directly. Your installer files everything on your behalf.
Before calling anyone, check current budget availability at selfgenca.com or your utility's SGIP page. Gather your income documentation or CARE/FERA enrollment first, since the equity budget won't move without it. The CPUC's Approved SGIP Developer List is the authoritative source for certified installers; some solar marketplace platforms like EnergySage also surface certified contractors, but verify any name against the official list.
Once you've signed with your installer, they file the reservation with your utility, locking in your rebate rate (no money moves yet). Installation follows standard permitting and inspection, with your installer handling interconnection paperwork. The one non-negotiable: Demand Response enrollment. DR qualifying programs have changed across cycles; before signing, ask your installer which program currently satisfies the requirement. No enrollment, no disbursement.
From there, the battery runs a 12-month performance period. It needs to demonstrate real use — a Powerwall sitting in backup-only mode with no charge/discharge activity isn't meeting the program's intent; one that's cycling around your rate plan's peak windows is. After the performance period, your installer submits the usage data and your remaining rebate balance gets issued.
The full timeline from reservation to final payment typically runs 12–18 months. Plan accordingly if you're trying to time this with other home energy upgrades.
The Performance Period Is Where Most People Leave Money Behind
The rebate gets you the hardware at a lower cost. The performance requirement means the hardware actually has to work.
That's where Grid Getter fits in. Grid Getter connects your Powerwall to California's time-of-use rate structures (PG&E's E-ELEC, SCE's TOU-D-PRIME and SDG&E's EV-TOU-5, the plans Net Billing customers are on, plus older plans like E-TOU-C) and automates the charge/discharge schedule around your actual peak windows. Instead of managing reserve settings manually or relying on the Powerwall's default behavior (which isn't calibrated to your specific utility plan), Grid Getter runs the schedule based on your utility's rate structure.
For SGIP purposes, that means your battery is cycling in a way that satisfies the Demand Response commitment in actual operation, not just on enrollment paperwork.
If you're planning a battery installation in 2026, do two things before you talk to a single installer. First, check your utility bill for CARE or FERA enrollment, or compare your household income to 80% of your area's median. Second, check the SGIP step tracker for your utility's equity budget. If you qualify and the budget is open or waitlisted, get in line now. If you don't, price the battery without SGIP and look at what it saves on your rate plan instead.
