California’s Self Generation Incentive Program (SGIP) is one of the first incentives for battery energy storage in the country. The program has been very successful, helping California to lead the nation in residential energy storage deployment.
Recently, the program has received additional funding, with a slightly revised charter for how to use those funds. I’ll be detailing the adjustments to SGIP and how it will impact individual, residential solar + storage shoppers in California.

And if you’re someone in our area of Southern California and you’re interested in a solar + storage system, then get a quote from us by using the link in the description below. We are a registered developer for the SGIP and can process your application to help you get the state rebate.
SGIP in a nutchell provides incentive payments to customers in California that install energy storage systems. Specifically for residential consumers, SGIP provides an upfront rebate based on the amount of stored energy in the battery you install.
The incentive program is a tiered-block program, meaning that the level of incentives gradually decline over time as more batteries are installed in the state.
This certainly leads to a first-mover opportunity to receive the highest level of rebates by being the first to act; however, given that the cost of energy storage has declined significantly over the last five years, California customers can be certain that SGIP continues to provide a sizable rebate for installing energy storage.
For residential customers, SGIP is currently in Step 5, which provides a $250 per kilowatt-hour (kWh) of stored energy rebate. According to California’s distributed generation statistics portal, the two most popular batteries in the state at present are the Tesla Powerwall 2 and the LG Chem RESU 10H which we offer.
With usable energy capacities of 13.5 kWh and 10 kWh, respectively, Step 5 of SGIP would provide between a $2,500 and a $3,375 rebate for purchasing a new battery in California.
Funding levels have increased, because in 2018, California Senate Bill 700 authorized and directed the California Public Utilities Commission (CPUC) to extend and fund SGIP for an additional five years beyond its original expiration date of January 1, 2021.
Over the next two years, the CPUC deliberated the amount of funds to direct towards the re-invigorated SGIP, with a final decision coming during January 2020. Ultimately, the CPUC adopted a decision that approved the additional funding of SGIP by injecting a further $675 million into the program over the next five years.
Combining that with carryover funds from the previous round of funding for SGIP means that there are now over $1 billion in SGIP incentives available.
Adjustments to program budgets have occurred
Now, given the increased threat from wildfires in California and the increasing prevalence of Public Safety Power Shutoffs (PSPS) throughout the state, the CPUC’s decision on the delivery of additional funds under SGIP is geared towards providing batteries to those customers who are most at risk of blackouts and power shutoffs.
In fact, nearly 60% of the current $1 billion dollar program budget for SGIP is dedicated for “Equity Resiliency” projects.
These projects are for people who meet one of a few specific qualifications:
Medical baseline customers,
Customers living in high fire risk areas,
Customers that rely on electric pump wells for water supply,
Customers who experienced PSPS events on two or more distinct occasions,
And critical facilities that provide services to these affected areas.
For customers who live in these areas and who are eligible for the Equity Resilience incentives, adding storage is not only a potential necessity of geography but now a financial no-brainer: the Equity Resilience incentive is at a level of $1,000 per kWh, meaning it should cover the entire installed cost of any residential energy storage system available on the market today.
The real question is how many batteries will be funded by the revised program?
At a $1,000 per kWh incentive rate for qualified Equity Resilience customers, the $613 million in incentives would fund between 45,000 and 60,000 batteries for disadvantaged customers and customers in high-fire risk areas.
The revised SGIP funding also sets aside $60 million for standard residential projects. If all of these funds were paid out at the current block rate of $250 per kWh, that would fund between 17,000 and 25,000 additional batteries.
Given that there are under 15,000 residential energy storage systems currently installed in California, the increased funding in SGIP will at a minimum increase overall battery deployment in the state fourfold.
