This is a list of electricity-generating power stations in the U.S. state of Connecticut, sorted by type and name. In 2023, Connecticut had a total summer capacity of 9,936 MW through all of its power plants, and a net generation of 40,666 GWh. In 2024, the electrical energy generation mix was 57.9% natural gas, 37.4% nuclear, 1.3% biomass & refuse-derived fuels, 1.1% solar, 1.1% hydroelectric, 0.3% petroleum, and 0.9% other. Distributed small-scale solar, including customer-owned photovoltaic panels, delivered an additional net 1,461 GWh to the state's electricity grid in 2024. This compares as nearly three times the amount generated by Connecticut's utility-scale solar facilities.
