General Electric will supply two high-efficiency 7HA.02 gas turbine generators for the Tennessee Valley Authority’s new combined-cycle Allen plant, which will replace TVA’s three coal-fired units.
TVA is retiring the units to meet the EPA’s December 2018 deadline to reduce coal emissions.
GE’s 7HA.02 gas turbines run on natural gas. The company says they are the world’s largest and most-efficient 60-hertz gas turbines. In baseload operation, a 2X1 7HA.02 combined-cycle power plant, when compared to a typical coal fired power plant, will reduce carbon dioxide emissions by about 65 percent and reduce both sulfur dioxide and nitrogen oxide emissions by over 95 percent.
The TVA Allen plant will have the capacity to generate 1,000MW of power in combined-cycle mode.
Last year the TVA said by 2020 it will cut carbon emissions amounting to half of what they were at their peak in 1995, in response to the EPA’s proposed guidelines.
