West Medway Generating Station II

 

Clean natural gas is the preferred fuel to run our dual-fuel generation units, but pricing changes or a lack of fuel can cause a power-supply shortfall, making dual-fuel units valuable

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​West Medway Generating Station II is owned and operated by West Medway II, a wholly owned subsidiary of Constellation. West Medway Generating Station II is a two-unit, 192-megawatt (MW) simple-cycle, dual-fuel electric generation facility located in West Medway, Massachusetts. The plant primarily uses natural gas and has the ability to also use ultra-low sulfur diesel (ULSD) for no more than 30 days per year.

West Medway Generating Station II went into commercial operation in 2019. Fast-start technology allows it to accelerate from start to full power in 10 minutes, making it ideal to support electric grid reliability by backing up wind and solar power systems. Its high-efficiency turbines, paired with advanced pollution-control technology, make it one of the cleanest peaker plants of its kind in the nation.

West Medway Generating Station II is co-located with a three-unit 124-megawatt oil-fueled power plant, West Medway Generating Station I.

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.

West Medway Generating Station II supports the Medway community with local real estate taxes, charitable donations, and sponsorships. Constellation works to advance many important causes through corporate giving efforts, including education, the environment, health and human services, the arts, community projects, and diversity efforts.
