PJM Interconnection, the grid operator in at least 13 states, is asking its customers to conserve power due to the weather, according to a company statement.
The group said it provided coverage for Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and Columbia. Serving approximately 65 million people in all or part of the District.
“Conserving electricity as much as possible between 4:00 am on December 24, 2022 and 10:00 am on December 25, 2022 will help ensure adequate power supply,” PJM said.
PJM recommends that consumers set their thermostats lower than usual and delay using major appliances such as stoves and dishwashers.
“CPJM continues to carefully monitor the power supply situation. It will do everything possible to keep power flowing in the area. If necessary, PJM may take additional measures such as reducing voltage. PJM is coordinating with generators, power suppliers and local utilities between efforts,” the statement said.
In a video on Twitter, PJM Sr. Vice President of Operations Mike Bryson thanked customers for their ongoing dialogue efforts.
Bryson said the risk of customer rolling outages was “very real”.
