Station manager Larry Sparks leads a tour of Duke Energy’s Dan River combined cycle plant in Eden. Natural-gas plants now produce about 18 percent of the electricity that Duke generates, up from under 2 percent a decade ago.

A natural gas intake at Duke Energy’s Dan River combined cycle plant. The company’s coal-fired production is down 52 percent of total volume in 2015, to about 33 percent last year.

“These gas plants are running all the time and at a high level of efficiency. It’s really changing the face of power generation here in North Carolina,” says said Swati Daji, Duke’s senior vice president in charge of fuels and system optimization, about Duke Energy’s natural gas plants in the state.

Duke Energy holds media tour of Eden plant

Duke uses its natural-gas plants strategically to meet spikes in demand because they are more car-like in their ability to accelerate to meet such surges linked to summer heat waves and winter cold snaps.

Station manager Larry Sparks leads a tour of Duke Energy’s Dan River combined cycle plant in Eden. Natural-gas plants now produce about 18 percent of the electricity that Duke generates, up from under 2 percent a decade ago.

A natural gas intake at Duke Energy’s Dan River combined cycle plant. The company’s coal-fired production is down 52 percent of total volume in 2015, to about 33 percent last year.

“These gas plants are running all the time and at a high level of efficiency. It’s really changing the face of power generation here in North Carolina,” says said Swati Daji, Duke’s senior vice president in charge of fuels and system optimization, about Duke Energy’s natural gas plants in the state.
