West Medway Generating Station is a three-unit, 173-megawatt (MW) station located in West Medway, Massachusetts.
West Medway's Rolls Royce Avon engines were the first of 12 dual-fuel engines installed in the world.
The three peaking were installed by Boston Edison following the 1965 East Coast blackout. The units were classified as "black start" (able to start up without outside power) for steam generating stations and to provide power to the local electric grid during times of peak demand.
Exelon purchased West Medway Generating Station in 2002.
