Exelon Corporation plans to shut down its Three Mile Island (TMI) nuclear power plant in Pennsylvania in September 2019.
It is said plans for closure will go ahead unless the firm receives state subsidies because the facility has not been generating profits.
Exelon's president and chief executive officer (CEO) Chris Crane said: “This is a difficult day, not just for the 675 talented men and women who have dedicated themselves to operating Three Mile Island safely and reliably every day, but also for their families, the communities, and customers who depend on this plant to produce clean energy and support local jobs.
“Like New York and Illinois before it, the Commonwealth has an opportunity to take a leadership role by implementing a policy solution to preserve its nuclear energy facilities and the clean, reliable energy and good-paying jobs they provide. We are committed to working with all stakeholders to secure Pennsylvania’s energy future, and will do all we can to support the community, the employees and their families during this difficult period.”
This facility is the latest to be affected by the country's focus on shale production due to an increase in production of cheap natural gas.
According to US Energy Information Administration, of the 99 nuclear power reactors with licence to operate in the country, five have been closed in the last five years.
In 1979, one of TMI's two reactors experienced a partial meltdown. This incident led to several reforms, including federal monitoring of nuclear power plants.
