Officials shut down the Oyster Creek nuclear plant in Lacey Township after the plant lost off-site power Monday.

The Nuclear Regulatory Commission says emergency generators powered safety systems and plant operators responded appropriately to the situation.

Officials believe the loss of power resulted from a ground of a high-voltage line that provides electricity to the nuclear plant in Ocean County.

JCP+L said the plant itself was not responsible for an outage early Monday morning that put 19,000 customers in Ocean County into the dark.
