Tennessee Valley Authority has ordered supply two high efficiency 7HA.02 gas turbine generators from GE for its combined-cycle Allen plant in Memphis, Tenn. The new plant will replace three coal-fired units that are being retired as TVA works toward a December 2018 deadline from the EPA to reduce coal emissions. GE’s 7HA.02 gas turbines run on natural gas.

According to GE, In baseload operation, a 2X1 7HA.02 combined-cycle power plant, when compared to a typical coal fired power plant, will reduce carbon dioxide (CO2) emissions by approximately 65 percent and reduce both sulfur dioxide (SO2) and nitrogen oxide (NOX) emissions by more than 95 percent. The TVA Allen plant will have the capacity to generate 1,000 MW of power in combined-cycle mode, the equivalent power that would be needed to supply 1 million U.S. homes.

The gas turbines are expected to be delivered to the site in August 2016 with commercial operation planned for May 2018.
