About electricity rates in Connecticut
Connecticut is a restructured state. Eversource and United Illuminating own and operate the distribution wires, but households may buy the generation portion of their service from a competitive supplier or stay on the standard service that the utility procures through regulator-approved contracts. Bills therefore show separate supply and delivery charges, and the delivery side is a large part of the total. The Public Utilities Regulatory Authority oversees the utilities.
Connecticut belongs to the New England grid run by ISO New England, where natural gas and the Millstone nuclear plant provide most of the power, with offshore wind and solar growing. Cold winters are heated mostly by oil and gas, though heat pumps are spreading, and humid summers bring air-conditioning peaks. Rooftop solar is now supported through a state tariff program that replaced traditional net metering for new systems.
