DIGHTON POWER PLANT, a 200 MW Natural Gas power plant in Bristol County, Massachusetts. Operated by DIGHTON POWER, LLC, commissioned 1999.
How DIGHTON POWER PLANT compares
With 200 MW of capacity, DIGHTON POWER PLANT ranks 14th among the 125 operating power plants Bywatts maps in Massachusetts and 11th of the 22 operating Natural Gas plants in the state. It accounts for about 3.7% of Massachusetts's operating Natural Gas capacity and 2.2% of all operating capacity in the state. Nationally it is the 540th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1999, it is newer than 50% of the 122 operating Massachusetts plants with a recorded commissioning year. It shares Bristol County with 8 other operating plants, including CLEARY FLOOD and DARTMOUTH POWER ASSOCIATES LP.
EIA-860 lists 1 generator at the site with 200 MW of nameplate capacity, all natural gas fired combined cycle technology. Net generation was 531 GWh in 2024 (a 30% capacity factor), about 2.1 times its 2022 output.
