New Generation

The nation's electricity demand creates the need for new, innovative generation technologies and an increasingly diversified fuel mix.

John W. Turk, Jr. Power Plant

The John W. Turk, Jr. Power Plant is setting a new standard for clean, energy-efficient coal-fueled generation. The first plant of its kind built in the United States, Turk uses ultra-supercritical generation technologies that use less coal and produce fewer emissions, including carbon dioxide, than traditional pulverized coal plants. The plant began commercial operation Dec. 20, 2012.

New chrome and nickel-based super alloys are used in the components of the plant's steam generator, turbine and piping systems that allow the plant to operate using steam at more than 1100 degrees Fahrenheit and a pressure above 3208 pounds per square inch absolute (psia) to produce electricity more efficiently.

The Turk Plant uses low-sulfur coal and state-of-the art emission control technologies, which enable the plant to meet emission limits that are among the most stringent ever required for a pulverized coal unit. The plant also was designed to allow for the retrofit of carbon dioxide controls.

Turk Plant received POWER Magazine’s 2013 Plant of the Year Award and earned AEP the Edison Electric Institute’s 2013 Edison Award, the electric power industry’s most prestigious honor.

Natural Gas Power Plants

AEP has added more than 4,800 megawatts of natural gas-fired capacity to its generating fleet in the past decade. Natural gas accounts for 23 percent of AEP’s total generating capacity.

AEP’s newest natural gas-fired generation units include:

  • Harry D. Mattison Plant, owned by Southwestern Electric Power Co., was completed in 2007.
  • J. Lamar Stall Plant, owned by Southwestern Electric Power Co., was completed in 2010.
  • Dresden Plant, owned by Appalachian Power, was completed in 2012.
Ultra Supercritical Generation

Ultra-supercritical Generation

Ultra-supercritical generation uses less coal and helps reduce emissions.
