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 demand periods and load balancing.
Exelon purchased West Medway from Boston Edison in 2002. The 3 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 demand. Its Rolls Royce Avon engines were the first of 12 dual-fuel engines installed in the world.
All Exelon facilities employ sophisticated emergency response plans to protect public health and safety. These plans are reviewed and approved by state governments and regulatory agencies. The emergency planning includes coordination with local counties, municipalities and school districts.
