List of power stations in Massachusetts
From Wikipedia, the free encyclopedia
This is a list of electricity-generating power stations in the U.S. state of Massachusetts, sortable by type and name. In 2023, Massachusetts had a total summer capacity of 12,850 MW through all of its power plants, and a net generation of 19,695 GWh.[2] In 2024, the electrical energy generation mix was 74.7% natural gas, 10.9% solar, 4.4% biomass, 3.8% hydroelectric, 0.9% petroleum, 0.9% wind, and 4.5% other. The state's last remaining nuclear power plant was retired in May 2019.[1]
Sources of Massachusetts utility-scale electricity generation in gigawatt-hours, full-year 2025:[1]
- Natural gas: 17,807 (75.8%)
- Solar: 2,529 (10.8%)
- Biomass: 875 (3.73%)
- Hydroelectric: 827 (3.52%)
- Petroleum: 402 (1.71%)
- Wind: 210 (0.89%)
- Other: 838 (3.57%)
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 4,064 GWh to the state's electricity grid in 2024. This compares as about 80 percent more than the amount generated by Massachusetts' utility-scale solar facilities that year.[1]
