Capacity: 344 megawatts
Location: Arden, North Carolina
Commercial Date: 1964
Status: Retired

The two-unit, 344-megawatt Asheville coal plant retired on Jan. 29, 2020. The plant started serving customers in June 1964.

The Asheville Combined Cycle Station, a cleaner-burning, highly efficient natural gas station, replaced the coal plant. In 2017, Duke Energy started building the new 560-megawatt combined-cycle natural gas plant to accommodate burgeoning growth in the area and meet customer demand. Building highly efficient natural gas plants is also part of the company's balanced approach to providing customers reliable and increasingly clean energy. Though the new natural gas plant is geographically located in Arden, N.C., its energy is fed to the grid, which benefits customers in both North Carolina and South Carolina.

The Asheville Combined Cycle Station is Duke Energy's most efficient in the Carolinas – and 75% more efficient than the now-retired coal plant it replaced.

Duke Energy customers benefit dollar for dollar from this efficiency through lower power plant fuel costs.

Because natural gas burns cleaner than coal, carbon dioxide emissions at the site have dropped by about 60% per megawatt-hour in comparison to the now-retired coal plant. Sulfur dioxide is expected to decrease by 99% and nitrogen oxides by 40%. Mercury has also been eliminated.

The Asheville site also has two simple-cycle combustion turbines capable of producing 320 megawatts of energy.

Information included in recent neighbor updates, along with work and progress at the site.



June 11, 2020  Beginning on June 15, we will begin nighttime work at our on-site landfill, which was approved for construction earlier this year. The shift to a 24-hour schedule, six days a week, is necessary to meet our basin excavation deadline of August 2022 and comply with the Mountain Energy Act. The work is interior to our site and is not expected to impact neighbors, though some may see lights or hear machinery in the distance. The nighttime work is expected to conclude this fall.
April 5, 2020 The new 560-megawatt Asheville Combined Cycle Station became fully operational with the remaining 100-megawatt steam turbine generator coming online.
Jan. 29, 2020 Duke Energy retired the two-unit 344-megawatt Asheville coal plant, marking the end of an era. The coal plant reliably served customers from 1964 to 2020.
Jan. 15, 2020 The Asheville Combined Cycle Station started producing 460 megawatts of energy with a second 180-megawatt combustion turbine generator coming online.
