U.S. nuclear energy facilities are initially licensed to operate for 40 years and a Nuclear Regulatory Commission (NRC) rule allows licensees to apply for initial and subsequent license renewals of up to 20 years each after the initial 40-year term. The NRC approved initial license renewal for Limerick on October 20, 2014, authorizing operation for Unit 1 and Unit 2 through 2044 and 2049, respectively.

Nuclear: An Ideal Foundation for Our Clean Energy Future
Limerick Clean Energy Center's two nuclear reactors in Pottstown, Pennsylvania can produce up to 2,317 megawatts (MW) of clean, emissions-free energy, enough electricity to power the equivalent of more than 1.7 million homes. Limerick sits on a 600-acre site and draws its cooling water from the Schuylkill River.
