Net Excess Generation Notes

For customers on Net Metering:

Excess generation at the end of each month is credited at the applicable retail electricity rate and rolled forward to future bills as a dollar credit. This credit rolls forward indefinitely to future bills but cannot be "cashed out".

For customers on the Feed in Tariff REG program:

All kWh produced by the solar system are paid at the applicable FIT rate. Credits are first applied to the customer’s bill. Any remaining credits are then paid to the customer monthly by check.

*Regrowth is a locked in rate for the term of the contract. Simplified applications (under 15kw) = $0.2775/kW for 15 years. Expedited applications (over 15kw) = $0.2615/kW for 20 years

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Rhode Island Energy before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
