The license renewal will enable Limerick to operate for another 20 years from its original 40-year operating licenses, which were set to expire in 2024 for Unit 1 and 2029 for Unit 2.
The new licenses will conclude on 26 October 2044 for Unit 1 and 22 June 2049 for the Unit 2.
Limerick site vice president Tom Dougherty said: "We are committed to running the plant at world-class levels through 2049, providing clean, safe, reliable energy while powering the local economy."
Capable of generating 2,345MW of clean and reliable electricity, which is enough for approximately two million homes, the Limerick Generating Station reduces the fossil fuels dependency as well as reduces greenhouse gas emissions that cause global warming.
If the power plant is decommissioned, the annual CO2 emissions would increase by 13.2 million tons, which is equivalent to putting more than 2.5 million cars on the road, according to a report by Continental Economics based on 2010 data.
According to the Continental Economics report, the generating station will reduce wholesale energy costs of $880m annually, on average, in Pennsylvania which results in consumer savings.
