How this performance incentive layers inside Rhode Island's deep stack
The RI Renewable Energy Growth (REG) Program pays based on actual measured generation rather than a one-time credit, one of Rhode Island's DSIRE-tracked solar incentive programs. Eligibility is scoped to residential customers, with a stated benefit of $0.16-$0.18/kWh for 15 years. DSIRE lists no scheduled sunset, though enabling legislation and appropriations can still be revised year to year.
That's the backdrop this incentive works against. Rhode Island averages 4.2 kWh/m²/day of usable sunlight and residential rates of 26¢/kWh, producing an estimated 7,358 kWh/year and $1,913 of annual utility offset on a typical 6 kW system costing $18,600. That baseline already implies a 9.7-year simple payback and a 25-year modeled net of roughly $29,225 before this incentive - every dollar this performance incentive delivers compresses that payback further.
Rhode Island bundles a deep incentive stack, so this program rarely stands alone. Rhode Island has 4 solar incentive programs indexed in DSIRE, including adjacent options like RI Solar Property Tax Exemption, RI Net Metering. The state's net-metering policy is classified as full, which governs how excess generation is credited and often decides whether a given program is worth claiming for a specific household.
