Gas-Fired Generation

General Electric announced in mid-January that it had received an order from the Tennessee Valley Authority (TVA) for two high-efficiency 7HA.02 gas-fired turbine generators to replace three coal-fired units at the 55-year-old Thomas H. Allen Fossil Plant, located in Memphis, to refurbish the Allen plant as a gas-fired, combined-cycle installation. The coal-fired units will be retired as TVA works toward a December 2018 deadline from the U.S. Environmental Protection Agency to reduce coal emissions. GE's 7HA.02 gas turbines run on natural gas and are the world's largest and most-efficient 60-hertz gas turbines. In base-load 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 over 95 percent. The TVA Allen plant will have the capacity to generate 1,000 megawatts of power in combined-cycle mode, the equivalent power that would be needed to supply 1 million U.S. homes.

The current coal plant was originally built by Memphis Light, Gas and Water Division and generates electricity for the Memphis area and a larger part of the western region covered by the TVA, as will the new combined-cycle plant. GE's 7HA technology offers a net combined-cycle efficiency of more than 61 percent, leading the industry with cleaner, reliable and cost-effective conversion of fuel to electricity. The gas turbines are expected to be delivered to the site in August 2016 with commercial operation planned for May 2018.
