VALLEY FORGE, Pa. (WTVN) -- The operator of the electric grid that serves Ohio, 12 other states, and the District of Columbia is asking customers to try and conserve electric on Tuesday.

"We're seeing another wave of frigid weather headed our way and that may push electricity demand to another record level of usage," said Ray Dotter, spokesman for PJM Interconnection.

The request is being made throughout the entire area served by PJM which stretches from Illinois to New Jersey and south to North Carolina. Demand for electricity
and the need for conservation is expected to be highest Tuesday evening.

PJM asks consumers to conserve electricity, if health permits - especially from 6 a.m. to 10 a.m. on Tuesday as well as between 5 p.m. to 9 p.m.

Dotter says customers can take simple electricity conservation steps like setting thermostats lower than usual, postpone using major electric appliances like stoves, dishwashers, and clothes dryers until midday or after 9 p.m. You should also turn off lights and appliances you don't need or are not using.

"Not asking for anything drastic," Dotter said.

If power usage gets too high, Dotter says they may have to reduce voltage levels. That's usually not noticed by customers because most appliances are made to run on a range of voltages.

"We have power supplies adequate for Tuesday, although it will be tight, that's why we're calling for conservation to make sure we have a little room to maneuver, a little margin if you will," he said.
