Luminant pursues thousands of MWs of gas plant additions/repowerings

The Luminant unit of Energy Future Holdings has filed for and received air permits from the Texas Commission on Environmental Quality (TCEQ) to build two natural gas combustion turbine generation units totaling 420 MW to 460 MW at each of Luminant’s existing DeCordova, Tradinghouse and Lake Creek generation facilities.

In a May 1 disclosure statement filed at its bankruptcy court in conjunction with a new reorganization plan, Energy Future Holdings also said that in 2014 and 2015, Luminant filed air permit applications with the TCEQ to build two natural gas combustion turbine generation units totaling 420 MW to 460 MW at each of its existing Valley and Permian Basin generation facilities. In 2014 and 2015, Luminant filed air permit applications with the TCEQ to build a combined cycle natural gas generation unit totaling 730 MW to 810 MW at each of its existing Eagle Mountain and DeCordova generation facilities.

In 2015, Luminant filed air permit applications with the TCEQ to build two combined cycle natural gas generation units totaling 1,460 MW to 1,620 MW at its existing Tradinghouse generation facility. The proposed combined cycle natural gas generation units would be alternatives to the natural gas combustion turbine generation units at Luminant’s DeCordova and Tradinghouse generation facilities.

The company noted: “We believe current market conditions do not provide adequate economic returns for the development or construction of these facilities; however, we believe additional generation resources will be needed in the future to support electricity demand growth and reliability in the ERCOT market.”

These new permits cover:

  • DeCordova, Combustion Turbine, two units, 420 MW to 460 MW, Air Permits Granted
  • DeCordova, Combined Cycle, one unit, 730 MW to 810 MW, Air Permits Pending
  • Eagle Mountain, Combined Cycle, one unit, 730 MW to 810 MW, Air Permits Pending
  • Lake Creek, Combustion Turbine, two units, 420 MW to 460 MW, Air Permits Granted
  • Permian Basin, Combustion Turbine, two units, 420 MW to 460 MW, Air Permits Granted
  • Tradinghouse, Combustion Turbine, two units, 420 MW to 460 MW, Air Permits Granted
  • Tradinghouse, Combined Cycle, two units, 1,460 MW to 1,620 MW, Air Permits Pending
  • Valley, Combustion Turbine, two units, 420 MW to 460 MW, Air Permits Granted

The potential combined cycle units at DeCordova and Tradinghouse would be an alternative to the potential combustion turbine units at these sites.

Luminant’s natural gas-fueled generation operations currently consist of 36 units at nine plant sites with 6,443 MW of nameplate capacity, including:

  • eight combined-cycle gas turbine (CCGT) units at Forney with total nameplate capacity of 1,912 MW;
  • six CCGT units at Lamar with total nameplate capacity of 1,076 MW;
  • two steam units at Graham with total nameplate capacity of 630 MW;
  • two steam units at Lake Hubbard with total nameplate capacity of 921 MW;
  • two steam units at Stryker Creek with total nameplate capacity of 675 MW;
  • one steam unit at Trinidad with total nameplate capacity of 240 MW;
  • four combustion turbines at DeCordova with total nameplate capacity of 260 MW;
  • six combustion turbines at Morgan Creek with total nameplate capacity of 390 MW; and
  • five combustion turbines at Permian Basin with total nameplate capacity of 325 MW.
