Air conditioners were on full blast as residents tried to stay cool during last week's heat wave. But Potomac Edison says it didn't set any records.

The utility says it generated 1,528 megawatts of electricity on June 29th at around 5:00 PM, which is the highest amount of power it produced so far this y ear. But Spokesman Todd Meyers says the all time peak level was actually reached in January, 2005, when the company then known as Allegheny Power generated 1,879 megawatts. "As hot as it was, sometimes the cold temperatures can be even more when it comes to a peak load day," says Meyers.

For many years, Potomac Edison and other nearby electricity companies were  winter peaking utilities, but all of that has has changed. "The former Allegheny Power, which, of course, had other utilities and other service areas, had been a winter-peaking utility. Then it flipped over in the 2000's to be a summer-peaking utility," says Meyers. But Potomac Edison continues to be a winter-peaking utility, he says.

Meyers also says he expects the June 29th record to be broken before the summer ends. "That was the level high for this year so far, and we still have a lot of summer left so it would not suprise me to see that eclipse," he says.

In the meantime, Potomac Edison recommends you turn up your air conditioner to at least 78-degrees to help stay cool and save energy on hot days. The company also advises you keep drapes closed in the daytime, and rearrange pieces of furniture, such as sofas, so they're not blocking the air register in your home.
