TVA Powers Up Memphis with Six New Mega-Turbines for Reliability
Published Date: 1/14/2026
Notice
Summary
The Tennessee Valley Authority (TVA) is building six new powerful turbines at its Allen facility in Memphis to generate about 200 megawatts of electricity. This upgrade will help keep the lights on for millions in the Tennessee Valley by making the power system more reliable and flexible as demand grows. The project supports TVA’s plan to provide affordable, steady energy and is moving forward now with construction and operation plans.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
200 MW of New Dispatchable Power
TVA will build six aeroderivative combustion turbines at the Allen facility in Memphis to generate approximately 200 megawatts (MW) of dispatchable power. This addition is intended to increase the flexibility and reliability of TVA's power system and support continued load growth across the Tennessee Valley (Tennessee and parts of Virginia, North Carolina, Georgia, Alabama, Mississippi, and Kentucky).
No-Action Could Raise Customer Costs
The Final EIS says that under the No Action Alternative TVA would need to obtain capacity from other sources and would likely purchase power from market sources, which could potentially result in increased costs to customers. TVA chose the construction alternative (six new units) rather than the No Action Alternative.
Moderate Long‑Term Air Quality Effects
The Final EIS anticipates moderate, long-term effects to air quality from constructing and operating the six new aeroderivative CT units at the Allen facility in Memphis, Tennessee. Residents near the plant could experience these air-quality effects over the long term.
Minor Long‑Term Local Impacts
The Final EIS identifies minor, long-term effects from the project on socioeconomics, climate change, utilities, surface water resources, and noise in the project area. These minor effects would occur in the local area around the Allen CT facility in Memphis, Tennessee.
