Leading Commercial Solar Provider in Rhode Island

Rhode Island’s stack is among the strongest in the Northeast: the Renewable Energy Growth (REG) program pays fixed, production-based rates per kWh for 15– or 20–year terms through Rhode Island Energy; the Renewable Energy Fund (REF) offers commercial grants up to $75,000 through RI Commerce; C-PACE financing through the RI Infrastructure Bank can cover up to 100% of project cost; and equipment is exempt from the 7% sales tax, with a 20-year property-tax exemption on added system value. Owners can also capture accelerated depreciation on systems they purchase.

REG is Rhode Island Energy’s performance-based incentive: commercial systems earn a fixed payment for every kilowatt-hour produced over a 15– or 20–year contract, with the rate locked at enrollment. Because the income is tied to production rather than shifting federal policy, it gives Rhode Island projects a predictable revenue floor — one of the main reasons the state’s solar economics remain compelling. Enrollment is set annually, so application timing affects your locked rate.

Rhode Island Energy credits net-metered systems for excess generation, directly reducing the property’s electric bill. Note that Rhode Island’s programs are largely either/or: a system generally enrolls in net metering or in the REG tariff, not both, so the right path depends on your load profile, rate class, and goals. We model both options in a feasibility analysis and recommend whichever produces the stronger 20-year return.

Commercial Property Assessed Clean Energy, administered by the Rhode Island Infrastructure Bank, finances up to 100% of a qualifying solar installation with no upfront cost and no personal guarantee. Repayment attaches to the property rather than the owner, which suits many commercial real estate holding structures and can transfer at sale.

REG enrollment and net metering run through Rhode Island Energy, which serves the large majority of the state across all five counties. Properties served by smaller municipal or island utilities may have separate arrangements — we confirm your territory and program eligibility as the first step of a feasibility analysis.

Plankton is a turnkey commercial solar developer and long-term owner-operator: we handle origination, engineering, interconnection, procurement, installation, and commissioning in-house, then operate and maintain the systems we build. In Rhode Island, that means one accountable partner from your first feasibility model through decades of production.

Commercial-scale projects generally need either 10,000+ square feet of open, structurally sound flat roof or 25,000+ square feet of parking. In practice that’s distribution and industrial buildings, grocery-anchored retail, office parks, self-storage, schools, multi-family, and houses of worship — particularly properties with meaningful daytime electricity loads.

Core components carry 25-year warranties, and because Plankton operates its own portfolio, we provide ongoing operations and maintenance on every system we build — monitoring production, servicing equipment, and managing incentive compliance for the life of the contract.

We design for the long term, so we won’t build on a roof with less than roughly 20 years of remaining life. Where the economics support it, a roof replacement can be financed into the project so the new roof and the system age together.

Three state-level clocks are running. REF grants release in limited funding rounds, and applications must precede installation. REG rates are set annually and lock at enrollment, so earlier applications lock earlier rates. And interconnection queues add lead time before any system can energize. Meanwhile, every month at Rhode Island’s high commercial rates is a month of unhedged expense — a feasibility analysis costs nothing and preserves every option.
