Self-Generation Incentive Program
The California Public Utilities Commission’s (CPUC’s) Self-Generation Incentive Program (SGIP) offers rebates for installing battery storage systems and other energy storage technologies which can function in the event of a power outage. For the Statewide program, the rebate is available after the application process is complete and the technology is installed.
Though the benefit of adding battery storage to your solar system is clear, we recognize the up-front investment can be cost prohibitive. That’s why we’ve launched the SGIP Assistance Program, to reduce out-of-pocket costs and help homeowners receive their rebates without delay.
To enable residential customers to strengthen their energy resiliency, SCP’s Assistance Program provides:
Connecting a battery storage system to your existing solar array will better prepare you for future power outages and use the renewable energy your system generates to its full potential. Learn more about basics of battery storage here.
Residential customers are eligible for a General Market rebate of approximately $200-$300/kilowatt-hour (kWh), depending on the system capacity. Funding is available on a first-come, first-served basis and the incentive amount declines over time.
General Rebate – Small Residential Storage
For projects 10 kilowatts (kW) and below
Current Step: Step 6
Current Incentive Rate: $200/kWh ($0.20/Wh)
Please note: Currently incentives are only available for “resiliency” customers. “Resiliency” customers are defined as customers who live in Tier 2 or Tier 3 High Fire Threat Districts (HFTD) OR have been shut off 2+ times during Public Safety Power Shutoffs (PSPS).
The budget for each residential General Market step is available to all residential customers, but when 50% of the budget for the current step is allocated to "non-resiliency" customers (defined as customers who do not live in Tier 2 or Tier 3 HFTD OR have not been shut off 2+ times during PSPS), then PG&E will pause acceptance of applications from non-resiliency customers and reserve the remaining 50% of the step’s budget for "resiliency" customers.
If you are not sure if you qualify as a “resiliency” customer, we can help determine your eligibility.
General Rebate - Large-Scale Storage
For projects 10.1 kW and above
Current Step: Step 4
Current Incentive Rate: $300/kWh ($0.30/Wh) or $220/kWh ($0.22/Wh) if taking the Investment Tax Credit.
More information about eligibility details and rebate amounts is available here.
Any residential SCP customer is eligible to participate in this program.
Customers must sign the SCP Customer Agreement which agrees:
For customers applying for the Small Residential Storage category at this time, you must meet “resiliency” criteria (defined as customers who live in Tier 2 or Tier 3 High Fire Threat Districts OR have been shut off 2+ times during PSPS).
Review our list of participating contractors. We recommend you get at least three quotes from prospective contractors and search for reviews. Once you select a participating contractor, they will coordinate with the SGIP Assistance Program on your behalf.

How can I become a participating contractor or installer?
Installers and contractors may email firstname.lastname@example.org for more information on participating in the program.
May I use this program to install a battery used only for emergency back up?
SGIP incentives are not available for backup-only purposes. The State program was designed to alleviate the demand on the utility grid during high demand periods (like during a summer heat wave when many use air conditioning at the same time), and funding is meant for technologies that provide value across the electricity grid.
Installing a battery system through SGIP means your system must “cycle” – charge and discharge on a regular basis – to meet some of your onsite electrical needs and provide value across the electricity grid. It can be scheduled to discharge itself over the course of several days (or a week) while maintaining an energy retainer in case of emergencies. As long as it reaches the equivalent of 100% discharge once per week, the system meets this requirement and also qualifies as not an emergency only system.
Do I need solar to participate?
While it is not required for you to have solar to participate, the main disadvantage to installing battery storage without solar is that during a power outage, you would not be able to recharge the battery from the grid while the grid connection to your home is shut off.
If you have rooftop solar, you can charge the battery during the day when your solar system is generating clean energy, and then have your home or business draw power from the battery during the evening hours when the grid power is less clean and more expensive. Installing batteries while having solar panels allows you to store your excess solar energy in batteries rather than selling it back to the grid at wholesale prices. This gives you more control over how you use your energy and where your excess energy goes, all while reducing your carbon footprint and increasing your personal resiliency.
Does the incentive check go to me, the installer, or SCP?
SCP can release the payment to either the homeowner or the contractor, depending on the project’s preference. In order for the homeowner or contractor to receive the up-front payment from SCP, the project application will assign SCP as the recipient of the SGIP rebate to be reimbursed at a later date.
