West Springfield Generating Station

The West Springfield Generating Station, also known by its corporate name EP Energy Massachusetts, LLC is a fossil-fuel fired power plant located in West Springfield, Massachusetts.The Station is a "peaking" facility, meaning that it primarily operates during peak electrical demand.

The facility consists of two 49 Megawatt (MW) combustion turbine generators (Units 1 and 2) fueled by natural gas or ultra low sulphur diesel fuel, one 18 MW jet turbine (Unit 10) that is fueled by kerosene, and one 107 MW simple-cycle steam boiler unit (Unit 3) burning either no. 6 fuel oil, ULSD or natural gas. The Station is located south of the Memorial Bridge in West Springfield, Massachusetts. The power plant and the adjacent West Springfield Substation were built in 1949 by Western Massachusetts Electric Company, a subsidiary of Northeast Utilities.

The plant uses the Connecticut River as its source of cooling water. Unit 3, as a steam unit, has to reject waste heat from its condenser to a water source. A once-through cooling system utilizing water from the river removes waste heat from Unit 3's condenser. The circulating water pumps are located in the plant's pump house across the highway from the facility directly on the Connecticut River.
