West Medway Generating Station I

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.

Constellation takes a safety-first approach in our culture and business practices. All Constellation generation facilities employ sophisticated emergency response plans to protect public health and safety. Plans are reviewed and approved by state governments and federal regulatory agencies. Emergency planning includes coordination with local and municipal officials, as well as thousands of volunteers and first responders.

To protect the safety and health of our employees, contractors, customers, and communities, we've implemented a number of initiatives to promote safe behaviors both on and off the job. These include a safety behavior observation program and focused initiatives on areas of high risk. We also offer safety training, which is integrated with leadership development programs for supervisors and managers, as well as new employee orientation. Finally, a safety peer group identifies successful pilot programs or new practices that can then be adopted by the entire organization.

Constellation’s power plants pay local real estate taxes every year to support county and township government, area schools, libraries, park districts, and other public services where our plants are located.
