Ensuring Grid Stability Through Fuel Diversity
Eddystone Generating Station plays a critical role in delivering reliable power through fuel diversity. Owned and operated by Constellation, this six-unit, 820-megawatt (MW) power plant is located on the Delaware River in Eddystone, Pennsylvania, just south of Philadelphia.
Eddystone Units 3 and 4, each with a capacity of 380 MW, were installed between 1967 and 1970. These subcritical steam boiler-turbine generator units can operate on either natural gas or oil, providing flexibility based on market conditions.
Units 10, 20, 30 and 40 are oil-fueled peaking units with a combined capacity of 60 MW. They are designed to run during periods of high demand and were installed in 1967 and 1970.
Construction of Eddystone began in the mid-1950s, with the now-retired Units 1 and 2 coming online in 1960. Both were supercritical steam boiler-turbine generator units that operated on coal. Unit 1 was retired in 2011, and Unit 2 followed in 2012.
