This is a list of electricity-generating power stations in the U.S. state of Massachusetts, sortable by type and name. In 2022, Massachusetts had a total summer capacity of 12,767 MW through all of its power plants, and a net generation of 21,026 GWh.[2] In 2023, the electrical energy generation mix was 76.1% natural gas, 10.2% solar, 4.8% biomass, 2.7% hydroelectric, 1% wind, 0.5% petroleum, and 4.8% other. The state's last remaining nuclear power plant was retired in May 2019.[1]
Massachusetts consumes about twice as much electricity as it generates, but is among the lowest electricity consumption states on a per capita basis, as well as on a per dollar of GDP basis.[3] Distributed small-scale solar, including customer-owned photovoltaic panels, delivered an additional net 3,668 GWh to the state's electricity grid in 2023. This compares as about 84 percent more than the amount generated by Massachusetts' utility-scale solar facilities that year.[1]
