How many megawatts of energy are used in the city of Wilmington annually?

Ken Little

Progress Energy spokesman Drew Elliot says city and countywide figures are not available.  Elliot did address the questions on a statewide scale.

He said Progress Energy Carolinas serves more than 1.4 million customers in North Carolina and South Carolina. Slightly fewer than 1.3 million are in North Carolina.

The average residential customer in North Carolina uses between 1,000 and 1,200 kilowatt-hours per month, or about 13,000 kilowatt hours per year.

“Of course, many customers may use significantly more or less than that,” Elliot says.

In general, Progress Energy Carolinas is a summer-peaking utility, meaning that the utility usually sees the highest energy use on hot, humid summer afternoons.

It’s all-time hourly peak use was 12,656 megawatt hours on the afternoon of Aug. 9, 2007.

“But we should note that this fact is highly weather-dependent,” Elliot says. “For instance, August 2009 was somewhat mild, while January 2010 was exceptionally cold. As a result, we saw more energy use in January than last August.”

Progress Energy’s s all-time winter peak occurred on the morning of Jan. 11, 2010, at 12,504 megawatts.

Elliot says that because the utility company maintains “a diverse generation portfolio,” it’s not possible to know exactly what sources generate the electricity used by a particular customer.

In 2009, Progress Energy generated 47 percent of the electricity it sold from coal, 46 percent from nuclear power, 6 percent from natural gas and oil, and 1 percent from hydroelectric sources.
