Providence and six other Rhode Island municipalities will soon launch a community electricity program aimed at increasing the state’s use of renewable energy and saving ratepayers money. Starting in May, the Providence Community Electricity Program will automatically enroll ratepayers unless they opt-out. Good Energy, a consulting group that helped negotiate the program, said it offers “competitive pricing, lowering electricity rates as well as increasing renewables.” The other municipalities joining the program are Barrington, Central Falls, Narragansett, Newport, Portsmouth and South Kingstown. Customers can opt-out without penalty. The standard rate of 9.4 cents per kilowatt hour is lower than what Rhode Island Energy will offer for the six-month period beginning in April.
