PJM Interconnection, the power grid operator for at least 13 states, asked its customers to conserve electricity due to the weather, according to a company statement.
The organization says it serves about 65 million people in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.
“Conserving electricity as much as possible between the hours of 4 a.m. on December 24, 2022, and 10 a.m. on December 25, 2022, will help ensure adequate power supplies,” PJM said.
PJM advised consumers to set thermostats lower than usual and postpone using major electric appliances such as stoves and dishwashers.
“CPJM continues to carefully monitor the power supply conditions. It will do everything possible to keep power flowing in the region. If necessary, PJM may take additional steps, such as reducing voltage. PJM is coordinating efforts among generators, power suppliers and local utilities,” according to the statement.
In a video on Twitter, PJM Sr. Vice President of Operations Mike Bryson thanked customers for their ongoing conversation efforts.
Bryson said the risk of rotating customer outages is “very real.”
