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.[1] 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.
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.[2] 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.
