Everything you need to know about the California Self-Generation Incentive Program (SGIP)
Key Details
Launched in 2001, the Self-Generation Incentive Program (SGIP) rewards users for generating their own electricity through wind turbines, fuel cells, various types of combined heat and power (CHP), and advanced energy storage.
Assembly Bill 209 of 2022 expanded the program's eligibility to include solar photovoltaic systems incorporating energy storage technologies in private residences.
The SGIP aims to change the market for distributed energy resource (DER) technology and contribute to lowering GHG emissions. The program is also geared towards decreasing demand and reducing customers' electricity consumption and bills.
As of 2023, Participants in the SGIP include retail electricity and gas consumers of Pacific Gas & Electric (PG&E), Southern California Edison (SCE) or Southern California Gas (SoCal Gas), and the Center for Sustainable Energy (CSE).
The SGIP program offers incentive rates for renewable generation and energy storage budget categories.
As of February 2023, the budget allocation of the SGIP program is divided as follows:
Energy Storage General Budget
88% of the incentive funding is set aside for energy storage technologies. Of this proportion, 7% is explicitly designated for small residential projects with a capacity of less than or equivalent to 10 kW.
Energy Storage Equity Budget
Regardless of the project scale, the incentive budget allots 3% to the residential energy storage equity budget for eligible residential (single-family and multifamily low-income housing). The non-residential energy storage equity budget receives no funding from the incentive budget.
Renewable Generation Budget
Generation technologies are given 12% of the incentive funding; there is no step-down structure for incentives.
Equity Resiliency Budget
Unused money from the Generation Technology budget has been used to create a $100 million Equity Resiliency Budget.
Heat Pump Water Heater (HPWH) Budget
For equity initiatives, a $4 million budget for heat pump water heaters (HPWH) has been set aside. Furthermore, 5% of the incentive money is set aside for general market HPWHs.
SJV Pilot Budget
A sum of $10 million has been put aside from SCE and PG&E’s unspent non-residential equity budget.
The Self-Generation Incentive Program's budget is split into renewable generation and energy storage.
Renewable Generation Incentive Rates
Energy Storage Incentive Rates
The total incentive funds for energy storage are split into five steps for large storage and seven steps for small storage in homes. Incentives for energy storage usually go down by $0.05/Wh between each step.
However, if the previous incentive step fills up within ten calendar days in all Program Administrator territories, the incentive for large-scale storage projects that aren't claiming the ITC will drop to the next step.
The small residential carve-out will cost $0.10 per kWh instead of $0.05 per kWh. For equipment bought before December 31, 2021, the incentive rate for large-scale storage projects that claim the ITC will stay 72% higher than the incentive rate for large-scale storage projects that don't claim the ITC in all steps.
The table below provides a breakdown of the energy storage incentive rates.
Step 1 | Step 2 | Step 3 | Step 4 | Step 5 | Step 6 | Step 7 | |
Energy Storage General Budget | $/Wh | $/Wh | $/Wh | $/Wh | $/Wh | $/Wh | $/Wh |
Large Storage (>10kW) | $0.50 | $0.40 | $0.35 | $0.30 | $0.25 | N/A | N/A |
Larger Storage Claiming ITC | $0.36 | $0.29 | $0.25 | $0.22 | $0.18 | N/A | N/A |
Residential Storage (<= 10kW | $0.50 | $0.40 | $0.35 | $0.30 | $0.25 | $0.20 | $0.15 |
Applications are generally assigned an incentive rate and reviewed in the sequence in which they are received. However, if the number of applications received on a single day exceeds the amount of funding available in a given Program Administrator's territory for a particular budget and step, a lottery will be held.
Applications are subject to the Program Administrator's incentive rates to which they pertain.
