BUNCOMBE COUNTY, N.C. (WLOS) — It’s been one year since Duke Energy’s coal plant at Lake Julian was retired, ushering in a new era with natural gas.
The absence of the smokestacks in the South Asheville skyline is a symbol of what’s been going on: Big changes as the company has moved away from its more than five-decades-long relationship with coal.
“It was about a year ago when customers across this region were receiving the benefits of the new power plant with a cleaner environment, lower fuel costs and host of other benefits,” said Jason Walls, district manager for Duke Energy.
By the end of last January, Duke had switched to its new Asheville combined cycle station. It fully replaced the 344 megawatt Asheville coal plant, which the company is still in the process of demolishing.
The new plant is a 560 megawatt plant powered by natural gas.
A report the EPA uses estimated more than 29,000 people live within a 3-mile radius of the plant, so what does this change mean for the community? News 13 spoke with two mountain environmental experts.
“I’ve spent a decade telling people how bad Duke was but we are moving in the right direction, so I’m a little uncomfortable not telling everyone how bad they are," said Hartwell Carson, MountainTrue's French Broad riverkeeper. "But it’s a good thing for the French Broad River."
One of the major concerns with the coal plant was groundwater contamination from coal ash, a toxic waste product of the former plant.
Up until last year Duke Energy had been storing the coal ash in unlined pits. It was a battle Carson had fought for years.
“Force them to reckon with their waste, which was a toxic stew of heavy metals that they had been dumping in unlined holes in the ground from the banks of the French Broad River,” said Carson.
Since last summer, Duke Energy has been building a lined, on-site landfill. It has also stopped trucking its coal ash to the Asheville Regional Airport and another waste site in Georgia.

Duke Energy is having to pay for its coal ash cleanup; a recent settlement is making the company pay for one-quarter of the cleanup costs between 2015 and 2030, plus another $100 million environmental fine.
“This is a state-of-the-art protection landfill that’s being designed to store ash forever,” Walls said. “It’s a really nice thing to kind of put coal ash in the rear view and look forward to the future.”
Lake Julian has also changed. It used to serve as the coal plant’s cooling site.
Now that it’s no longer needed, the water is returning to more mountain-like temperatures.
“Lake Julian at some point was over 100 degrees," said Carson. "We had done some monitoring years ago, and Lake Julian was an extremely unnatural waterway for North Carolina. That’s a positive thing to return it to what it’s supposed to be.”
However, according to some, it’s not all positive.
Kelly Sheehan Martin is the director of the Sierra Club’s Beyond Dirty Fuel Campaign. She tracks how power plants operate across the country.
“I think that Duke Energy, by switching from one big polluting coal plant to another big fossil fuel plant, really missed a huge opportunity here,” said Sheehan Martin.
According to Duke Energy, the new natural gas plant cuts carbon dioxide emissions by 60%, sulfur dioxide by 99%, nitrogen oxides by 40% and completely eliminates mercury.
Those critical of natural gas point to the way it's obtained -- through a controversial process known as fracking, which means drilling into rock to release the gas.

Sheehan Martin said that natural gas is not a resource with an endless supply, like solar or wind energy.
She said she wishes the company would have made a hard switch from coal to a renewable energy source.
“So you’re saying that they could have kept the coal plant running for a little bit longer?” News 13’s Caitlyn Penter asked.
“Maybe a year or two if that’s what they needed,” Sheehan Martin said. “Now we have a situation where we are locked into reliance on fossil fuels for decades to come.”
Leaders from Duke Energy said they remain committed to the goal of net zero carbon emissions by 2050.
“It’s aggressive, but it’s attainable if we work together as a community to make that happen,” Walls said.
DUKE ENERGY EXPECTS NO SAFETY IMPACTS FROM COAL PLANT SHUTDOWN
Once the coal ash has been fully moved to the new landfill, the old site where it was stored will be covered in solar panels.
In the last year, the company has also started using battery storage sites to store some of its energy produced by the natural gas plant.
“We see a future where renewables will certainly increase. You know natural gas will provide a lower carbon reliable generation,” Walls said.
For those who fought for the end of the coal plant, they said the fight for a cleaner community is still not over.
As the end of the coal plant was a step forward, they said they’re prepared to keep holding Duke Energy accountable.
“They didn’t want to close the coal plant, they didn’t want to clean up their coal ash, but they were held accountable by the citizens of North Carolina and the government of North Carolina to do that," Carson said. "I think they’ll do that if we hold their feet to the fire."
