The California Self Generation Incentive Program (SGIP) offers very attractive rebates for solar + battery storage systems and other renewable energy technologies, except when funding runs out.
The residential Equity Resiliency program is an exceptional incentive for customers who qualify by being in a tier 2 or tier 3 High Fire Threat District (HFTD) or an area that has had at least two Public Safety Power Shutoff (PSPS) events and have a critical need for electric power, such as a medical condition or relying on well water. The rate as of September 1, 2020 is $1.00/Wh of effective storage. For example, a customer installing a SolarEdge StorEdge photovoltaic system with a nameplate energy capacity of 19.6 kWh and an SGIP verified effective capacity of 17.67 kWh would receive a rebate of $17,670. The SGIP Equity Resiliency program is currently open for applications. The HFTD areas cover the great majority of the Mother Lode and the map can be seen at: https://ia.cpuc.ca.gov/firemap/
The program for Small Residential Storage has a more modest incentive rate of $0.25/Wh and the program is currently in Waitlist status. As more funds are collected, projects on the wait list may be funded. Projects on the wait list are addressed in the order they were received. However the SGIP Handbook also goes on to say that there is a “soft target” of half of the small residential budget going to HFTD areas or areas subjected to at least two PSPS events. This soft target would be implemented by pausing acceptance of applications from customers not living in such areas. Neither the SGIP Handbook nor responses to my email questions to the Program Administrator state explicitly that applications can be submitted while the program is in Waitlist status, but the implication is that they can be submitted, at least in HFTD and PSPS areas.
