Rhode Island Energy customers will see slightly higher electricity rates this summer, according to state regulators. Residential ratepayers will be charged 10.3 cents per kilowatt hour, which is lower than the previous six-month period of 17.8 cents, but still 32% higher than last summer. Meanwhile, Providence residents can choose from four plans with sliding costs based on their preference for renewable energy. Three out of the four plans offered by the Providence Community Electricity program are cheaper than Rhode Island Energy’s default rate, with the fourth plan costing more at 12.3 cents per kilowatt hour. The rates for Rhode Island Energy begin in April and end in September, while the Providence plans start in May and end in November.
