Renewable Energy Growth Program (REG):

The REG program offers fixed dollar-per-kilowatt hour payments for all energy produced over a 20 year term. The system owner may elect to receive a separate check for all system production, or associate an electric account to incorporate bill credits. National Grid opens several enrollments per year to accept projects into the program through a competitive bidding process.

Commercial Property Assessed Clean Energy Program (C-PACE):

Property owners may be eligible to finance up to 100% of clean energy project costs, including energy efficiency upgrades and roof replacement, by financing through the C-PACE program with no money down. The loan is paid back to the municipal tax assessor over a long term. The C-PACE program is sponsored by the Rhode Island Infrastructure Bank. Find out more: http://ri-cpace.com/
