WinPower products

The program has different products to let you find the right balance of cost and renewable electricity. Renewable electricity will be certified by purchasing and retiring Renewable Energy Certificates (RECs), the accepted legal instrument used to track renewable energy generation and to substantiate claims of renewable energy use. Learn more about RECs.

Please note: Prices for all options in the WinPower program include a $0.001/kWh administration fee. Program prices could increase as a result of a change in law that results in a direct, material increase in costs during the term of the electricity supply agreement. Program prices apply only to the electricity supply portion of your Eversource electric bill. Delivery charges on your Eversource electric bill are not affected by the WinPower program.

For new Industrial customers and for those customers who have previously opted-out of the program, the Program’s supplier may offer a market rate.
