Limerick is built on a 600-acre site and draws its cooling water from the Schuylkill River. Units 1 and 2 began commercial operation in February 1986 and January 1990, respectively.
Both of Limerick’s units are boiling water reactors designed by General Electric. Unit 1 is capable of generating 1,149 net megawatts (MW), while Unit 2 is capable of generating 1,146 net MW. Together, they can produce enough energy to power more than 2 million average American homes.
Generating More Low-Carbon Electricity
As part of Exelon 2020, Exelon Nuclear launched a series of planned power uprates across the company's nuclear fleet that will generate additional generation capacity within 8 years without turning a spade of earth. Uprate projects improve the efficiency and increase electricity output of a nuclear generating unit through upgrades to plant equipment. The projects take advantage of new production and measurement technologies, new materials and learning from a half-century of nuclear power operations.
License Renewal
Limerick Generating Station is committed to producing safe and reliable electricity for Pennsylvania and as part of this commitment we intend to apply to the U.S. Nuclear Regulatory Commission (NRC) for a 20-year extension to our original operating license. We are committed to running Limerick safely and reliably well into the future.
Emergency Planning
Limerick employs a sophisticated emergency response plan to protect public health and safety approved by the Nuclear Regulatory Commission (NRC) and the state of Pennsylvania. The Emergency Plan includes coordination with local counties, municipalities and school districts.
Supporting the Local Economy
Limerick has approximately 800 permanent employees. The majority of Limerick’s employees live in Berks, Chester and Montgomery counties. The station’s annual payroll is approximately $66 million. During refueling outages, Limerick employs almost 1,200 temporary contractors who boost the local economy during their stay.
