Can I combine Rhode Island RE Growth, REF, and net metering?

No. A solar project uses RE Growth or net metering. REF cannot be paired with RE Growth; an eligible REF project may use net metering. Model these paths separately.

Can heat-pump and battery programs apply alongside solar?

They may apply to different equipment, but eligibility, funding, and payment terms must be confirmed under each current official program. Do not assume every benefit stacks.

What RE Growth rate should a residential estimate use?

For Program Year 2026, Small Solar I is 31.55 cents per kWh for 15 years. Solar II has a different rate and term, so the correct class must be selected before calculating value.

Solar + heat-pump planning without double-counted incentives

Whole-home economics depend on the solar tariff path, actual energy load, financing, and current equipment-program eligibility. Compare compatible scenarios instead of combining RE Growth, REF, and net metering.

RE Growth path

Use the official rate and term for the enrolled project class.
Do not add net-metering credits during the RE Growth contract term.
Do not include an REF rebate on the same project.

Eligible REF + net-metering path

Confirm the current REF grant round and project eligibility before installation.
Use tariff-specific import and export components, not a retail-rate percentage.
Do not add RE Growth income to this scenario.

Heat-pump and battery programs

Treat equipment-specific rebates and demand response as separate eligibility checks.
Confirm current funding, equipment lists, enrollment, and dispatch terms.
Base savings on the home load and selected solar path, not a statewide promise.

Build a path-specific estimate

A defensible proposal should show the utility and customer class, import and export components, effective dates, the selected solar program, and separate heat-pump and battery assumptions. No savings or eligibility is guaranteed.
