After a forced shutdown early last week, operators returned Calvert Cliffs Nuclear Power Plant in Lusby, MD, to full power Friday.

Both of the plant’s reactors shut down automatically April 7 when an offsite grid disturbance caused widespread power outages in the region.

Once the cause of the disturbance ended up identified, Calvert Cliffs operators began a “comprehensive series of inspections and tests before synchronizing both units to the regional power grid,” Calvert Cliffs officials said in a release.

More than 70,000 customers in Southern Maryland and Washington, D.C., were without power April 7 after an equipment failure at the Ryceville electricity substation near the St. Mary’s/Charles counties line.

Officials said the outage was the result of an explosion at a Southern Maryland Electric Cooperative (SMECO) power plant several miles south of nation’s capital. The explosion appeared to have been the result of a high-voltage conductor falling to the ground, according to a SMECO official. No one suffered an injury, company officials said.

Department of Homeland Security officials said just after the outage began they were looking into the outage, but believed at the time there was no reason to believe the power failure had any connection to terrorism or other criminal activity.
