List of power stations in Massachusetts

Sources of Massachusetts utility-scale electricity generation in gigawatt-hours, full-year 2024: ^[1]

1. Natural gas: 16,203 (76.1%)
2. Solar: 2,127 (9.99%)
3. Biomass: 925 (4.34%)
4. Hydroelectric: ^[a] 774 (3.64%)
5. Petroleum: 177 (0.83%)
6. Wind: 169 (0.79%)
7. Other: 917 (4.31%)

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]

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]
