Delivering Grid Stability with Fast-Start Technology
West Medway Generating Station II combines speed, flexibility and advanced technology to ensure reliable power. Owned and operated by West Medway II, a wholly owned subsidiary of Constellation, this two-unit, 192-megawatt (MW) simple-cycle, dual-fuel electric generation facility located in West Medway, Massachusetts went into commercial operation in 2019. It primarily uses natural gas and can also operate on ultra-low sulfur diesel (ULSD) for up to 30 days per year.
Fast-start technology allows the plant to accelerate from start to full power in 10 minutes, making it an ideal resource for backing up wind and solar power systems and supporting grid reliability. Its high-efficiency turbines and 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.
