The two units of the power plant were shutdown automatically due to localized grid disturbance that resulted in power outages in the Washington, D.C./Maryland area.
Calvert Cliffs nuclear power plant operators carried out comprehensive series of inspections and tests, once the cause of the event was identified, and then synchronized both units to the regional power grid.
The nuclear power plant is owned and operated by Constellation Energy Nuclear Group (CENG), a joint venture between Exelon and Électricité de France.
Maryland’s only nuclear energy facility, the Calvert Cliffs power plant features two units, which are capable of generating over 1,700 net MW per year, enough to power over one million average homes.
Located on the western shore of the Chesapeake Bay, about 50 miles southeast of Washington, D.C, the nuclear power plant unit 1 started operations in 1975 and unit 2 in 1977.
