Maryland one of 13 states warned of rolling blackouts, asked to conserve
HARRISBURG, Pa. (AP) — The operator of the mid-Atlantic electricity grid for 65 million people is calling for people to conserve electricity into Christmas morning, warning of rolling blackouts because power plants are having difficulty operating in the freezing cold.
Pennsylvania-based PJM Interconnection issued the emergency call for conservation system-wide across its 13-state footprint, including Maryland, and said it is in touch with state government officials throughout the region.
PJM asked electricity customers to set thermostats lower than usual, if health permits; postpone use of major electric appliances such as stoves, dishwashers and clothes dryers; and turn off non-essential electric lights, equipment and appliances.
Commercial and industrial power users have also been asked to cut back.
PJM officials said simultaneous increased demand across its electric system came as some power plants are having difficulty operating in the extreme cold. They warned of rolling blackouts and said they wanted people to be prepared.
"It'll be short-lived, we'll do everything we can to prevent it, but it is a real possibility," said Mike Bryson, PJM's senior vice president for operations.
The blinding blizzards, freezing rain and frigid cold that enveloped much of the United States knocked out power to an estimated 1.7 million households and businesses.
PJM territory covers all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and Washington, D.C.
