Allen Aeroderivative Combustion Turbine Project
Shelby County, Tennessee
TVA is proposing the construction of six natural gas-fired aeroderivative combustion turbines (Aero CTs) to the existing Allen Combustion Turbine site near Memphis, Tennessee. These units would generate approximately 200 megawatts of power– enough to power up to 117,000 homes.
The proposal would increase the flexibility and reliability of TVA’s power system by improving transmission stability in the western Tennessee region and by providing new, dispatchable generation to support the continued system load growth experienced over the past few years.
Aero CTs are highly efficient peaking units that can quickly achieve full generating capacity. They are also extremely flexible with synchronous condenser capabilities that could greatly improve grid resiliency. The reliability and flexibility provided by Aero CT units would also help TVA to expand and integrate renewable energy resources onto its electric grid.
Under the proposal, TVA would also continue to operate two of the existing CT units at Allen in order to provide up to 120 megawatts of additional power. These two units had previously been slated for retirement but are in good condition and able to continue operations.
On October 12, 2023, TVA issued a Notice of Intent pursuant to the National Environmental Policy Act (NEPA) to initiate a review of the potential impacts on the environment associated with the proposal. TVA requested public comments on the scope of the review, alternatives to be considered, and environmental issues that should be addressed.
In late October 2023, TVA hosted an in-person public open house in Memphis to provide information about the project and gather public input. TVA also hosted a public webinar on November 2, 2023. A recording of the virtual webinar can be viewed by clicking the link below.
TVA will issue a Scoping Report that summarizes the input received during the public scoping period. In Spring 2024, TVA plans to publish a draft environmental document for public review and comment.
