Valley Forge, Pa., July 7, 2010 — PJM Interconnection, the electric grid operator for more than 51 million people in 13 states and the District of Columbia, today requested the public to conserve electricity. The call for conservation was prompted by the intense heat wave.
The request is being made for the service territories of Atlantic City Electric, Baltimore Gas and Electric Co., Delmarva Power, Dominion, Jersey Central Power & Light Co., PECO, Pepco and Public Service Electric & Gas Co.
Demand for electricity is expected to increase as the excessive heat and humidity continue. PJM asks customers to conserve electricity, if health permits — especially between 3 p.m. and 7 p.m. Electricity customers can take simple electricity conservation steps:
* Close curtains and blinds to keep out the sun and retain cooler air inside,
* Postpone using major electric household appliances such as stoves, dishwashers and clothes dryers until the cooler evening hours,
* If health permits, set air conditioner thermostats higher than usual, and
* Turn off electric appliances and equipment that you do not need or are not using.
Conserving electricity will help ensure adequate power supplies. PJM 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.
Utility customers in load management programs in the affected service territories have been told to reduce their electricity use. In return for payments, these customers agreed to eliminate or reduce their use of electricity when told to do so.
PJM is communicating about the situation with state government officials throughout the region. PJM’s region includes all or parts of Delaware, Indiana, Illinois, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia. PJM is coordinating efforts among generators, power suppliers and local utilities.
