The Self-Generative Incentive Program (SGIP) recently announced changes that might make it easier for property owners to upgrade their solar batteries and qualify for rebates and credits. As of February 18, 2025, home and business owners can benefit from increased load justification and storage thresholds.
The changes include the following:
- Replaces the storage system 10 kilowatt (kW) load justification threshold with a 15 kilowatt-hour (kWh) load justification threshold and establishes a 30 kWh incentive cap for single-family residential projects in all SGIP storage budgets;
- Replaces the multifamily storage system 5 kW per tenant unit load justification threshold with a 12.5 kWh per tenant unit load justification threshold in all SGIP storage budgets;
- Replaces the residential storage sizing methodology for storage systems above 15 kWh from sizing to the peak demand in the past 12 months in kW to:
- Sizing a storage system paired with solar generation to the average daily excess solar generation during a summer calendar month in kWh;
- and Sizing a standalone storage system to the average daily energy consumption during the 4-9 p.m. window during a summer calendar month in kWh;
- Updates the resiliency modular oversizing policy in the Equity Resiliency Budget to kWh. Host customers are eligible for modular sizing as long as more than 50 percent of the modular capacity of the additional module is needed based on load justification; and
- Replaces the 10 kW threshold for residential projects between the Small Residential Storage and Large-Scale Storage budgets with a 30 kWh threshold.
Install a New Tesla Powerwall with Confidence
The revised load justification and storage limits may allow homeowners and residential property owners to apply for incentives with their existing Tesla Powerwall or when they upgrade to a more robust system.
Consider the following configurations that no longer require sizing justification:
- Up to one Tesla Powerwall3 (rated capacity of 11.5kW, TESC of 13.2kWh)
- Up to three Enphase IQ5Ps (rated capacity of 11.52kW, TESC of 14.277kWh)
- Up to one Tesla Powerwall2 (rated capacity of 5kW, TESC of 13.2kWh)
- Up to one Franklin (rated capacity of 10kW, TESC of 13.6kWh)
- Up to one new Franklin aPower2 once on the approved list (rated capacity 10kW, TESC of 15kWh)
