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.
In preparation for the next wildfire season, the CPUC has prioritized funding for communities living in high fire-threat areas, communities who have experienced two or more utility Public Safety Power Shut-off (PSPS) events, and low income and medically vulnerable customers.
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 streamlined the SGIP application process to reduce out-of-pocket costs and help homeowners receive their rebates without delay.
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 the basics of battery storage here.
To get started, please review the customer eligibility list below and verify that your project is eligible. Next, choose from a list of participating contractors and installers who will coordinate with the SCP Assistance Program on your behalf. We recommend you get at least three quotes from prospective contractors and search for reviews.
SGIP Assistance Program Participating Contractors
Customers may receive rebates which can cover up to the full cost of a battery and installation, depending on which CPUC categories are applicable.
Based on SGIP program guidelines, any residential customer is eligible for a General Market SGIP rebate of approximately $250/kilowatt-hour, which means the rebate covers approximately 25% of the cost of an average energy storage system.
There are two additional categories offering increased SGIP rebates for residential customers: Equity and Equity Resiliency. For these categories, the cost of both the energy storage technology and the installation may be fully covered.
To be eligible for Equity Resiliency, you must meet the following criteria:
Fulfill (1) Primary Qualifier:
• Located in Tier 2 or Tier 3 High Fire Threat District. View map here
Experienced two or more PSPS (Public Safety Power Shutoff) events
Fulfill (1) Additional Qualifier:
• You are eligible or enrolled in Medical Baseline
• You have notified PG&E of a potentially life-threatening illness/condition if the power shuts off
• You rely on electric-pump wells for water supply
• You live in a disadvantaged community
• Are a low-income renter or homeowner
• Participating in one of the following solar programs: MASH, SASH, DAC–SASH, or SOMAH

What is the SGIP Equity Resiliency budget?
The Equity Resiliency budget is new funding made available by the CPUC for SGIP. In preparation for the next wildfire season, the CPUC has authorized an additional $612 million in funding to prioritize communities living in high fire-threat areas, communities who have experienced two or more utility Public Safety Power Shut-off (PSPS) events, and low income and medically vulnerable customers.
This new category provides a higher SGIP rebate to ensure that homeowners who meet the above criteria are at the front of the line to receive competitive incentives for battery storage.
Does the incentive check to go me, the installer or SCP?
SCP can release the upfront payment equal to the expected SGIP incentive 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.
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 heatwave when many use AC 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.
