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
Eddystone Generating Station is owned and operated by Constellation. It is a six-unit, 820-megawatt (MW) power plant, located on the Delaware River in Eddystone, Pennsylvania, just south of Philadelphia.
Eddystone Units 3 and 4, each with 380 MW capacity, are subcritical steam boiler-turbine generator units that can run on either natural gas or oil, depending on market conditions. These units were installed between 1967 and 1970.
Units 10 and 20 and 30 and 40, with a total combined capacity of 60 MW, are pairs of oil fueled peaking units that run during periods of high demand. These units were installed in 1967 and 1970, respectively.
Construction of Eddystone began in the mid-1950s, with the now-retired Units 1 and 2 coming online in 1960. Those units were both supercritical steam boiler-turbine generator units that operated on coal. Unit 1 was retired from service in 2011, and Unit 2 was retired in 2012.
