List of power stations in Connecticut
Sources of Connecticut utility-scale electricity generation:
full-year 2023[1]
This is a list of electricity-generating power stations in the U.S. state of Connecticut, sorted by type and name. In 2022, Connecticut had a total summer capacity of 10,108 MW through all of its power plants, and a net generation of 43,054 GWh.[2] In 2023, the electrical energy generation mix was 61.3% natural gas, 34.2% nuclear, 1.1% biomass & refuse-derived fuels, 1% solar, 0.9% hydroelectric, 0.4% petroleum, and 1.1% other. Distributed small-scale solar, including customer-owned photovoltaic panels, delivered an additional net 1,243 GWh to the state's electricity grid in 2023. This compares as nearly three times the amount generated by Connecticut's utility-scale solar facilities.[1]
