Oil-fueled electric generation facilities are part of our Peaking Division, operating, as needed, during peak-demand periods and for load balancing
West Medway Generating Station I is operated by Constellation. The three-unit, 124-megawatt (MW) oil-fueled electric generation facility is located in West Medway, Massachusetts. The Peaking Division consists of a number of intermediate and peaking fossil power plants, located in southeastern Pennsylvania, Massachusetts, and Illinois. These units are used as needed for peak energy demand periods and load balancing.
Constellation purchased West Medway from Boston Edison in 2002. The three peaking units, fueled by oil, were installed by Boston Edison following the 1965 East Coast blackout. The units can be started without outside power and provide electricity to the local electric grid during times of peak energy demand. Its Rolls Royce Avon engines were the first of 12 dual-fuel engines installed in the world.
West Medway I is co-located with West Medway Generating Station II, a two-unit, 192 MW simple-cycle, dual-fuel power plant that began operation in 2019.
