Commercial Scale Renewable Energy Grants (Commerce RI)

March 23, 2023


The Rhode Island Commerce Corporation (Commerce RI) seeks to fund commercial scale renewable energy projects  generating electricity for onsite- consumption. Commerce RI provides incentives for renewable-energy projects. Incentive programs are funded by the Rhode Island Renewable Energy Fund (REF) and alternative compliance payments (ACPs) from the state’s renewable portfolios standard (RPS). 


Any legal business entity, municipality, non-profit, and affordable housing are eligible for funding. All projects must be located on Rhode Island and must be used for on-site consumption. Grants are available for electricity-generating renewable-energy systems greater than 10 kilowatts (kW). Eligible technologies include solar, wind, ocean, small hydro, biomass, and fuel cells. Customers participating in the RE Growth Program offered by National Grid are not eligible for the program.
