SWEPCO Generation

Our long-range plan moves SWEPCO toward a cleaner energy future with more low-cost wind and solar energy as part of our diverse energy source mix over the next 20 years.

High-efficiency natural gas, advanced coal technology and updated environmental controls at multiple generating units are also at work for SWEPCO customers.

As we further diversify the energy sources serving our customers, we remain committed to providing safe, affordable and reliable electric power.

SWEPCO Power Plant Map and List

Wind power at work

SWEPCO customers are served by 469 megawatts of wind power purchased from facilities in Texas, Oklahoma, and Kansas. Learn more. More wind energy is planned as SWEPCO will be seeking regulatory approval of a proposal to acquire new wind generation facilities.

High-efficiency Natural Gas

SWEPCO's J. Lamar Stall Unit at Arsenal Hill, a 508-megawatt (MW) combined-cycle natural gas unit, began commercial operation in June 2010 in Shreveport, La. Combined-cycle plants generate electricity more efficiently and consume less fuel per kilowatt-hour of output than conventional gas-fueled generators. The Stall Unit generates electricity with a gas-fueled turbine and recovers exhaust heat from that process to produce additional electricity in a steam turbine.

Advanced Coal Technology

The John W. Turk, Jr. Power Plant in Fulton, Ark., is one of the cleanest, most efficient coal-fueled plants in the United States. The 600-megawatt (MW) facility began operation in December 2012 as the first "ultra-supercritical" unit in operation in the United States. Its advanced coal combustion technology uses less coal and produces fewer emissions, including carbon dioxide, than traditional pulverized coal plants. State-of-the art emission control technologies and the use of low-sulfur coal enable the Turk Plant to meet emission limits that are among the most stringent ever required for a pulverized coal unit. See fact sheet.

Additional Environmental Controls

Environmental retrofit projects were completed at five SWEPCO coal-fueled generating units between 2013 and 2016 – Flint Creek at Gentry, Ark.; Welsh Units 1 and 3 at Pittsburg, Texas; Pirkey at Hallsville, Texas; and Dolet Hills at Mansfield, La. Welsh Unit 2 was retired in 2016. The environmental controls were required to meet stringent U.S. Environmental Protection Agency regulations. The plants continue to serve as reliable power sources for customers and to maintain SWEPCO’s diverse energy mix. See Flint Creek and Welsh fact sheets.
