PJM Interconnection ensures the reliability of the high-voltage electric power system 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. PJM coordinates and directs the operation of the region’s transmission grid, which includes 62,556 miles of transmission lines.
The call for conservation throughout the region served by PJM is prompted by the continuing frigid weather.
Demand for electricity is expected to increase because of the extremely cold weather. PJM asks consumers to conserve electricity today, if health permits – especially from 6 to 9 a.m. and 3 to 7 p.m. Electricity customers can take simple conservation steps:
*Set thermostats lower than usual, if health permits.
*Postpone using major electric appliances such as stoves, dishwashers and clothes dryers until mid-day or after 9 p.m., when the demand for electricity decreases.
*Turn off electric lights and appliances that you do not need or are not using.
PJM continues to carefully monitor the power supply conditions and will do everything possible to keep power flowing in the region. If necessary, PJM will take additional steps, such as reducing voltage.
