TVA Talks Power Grid Improvements Ahead of Winter Storm

TVA has added 2,000 megawatts of power capacity and completed over 400 maintenance tasks to ensure grid reliability during the anticipated winter storm.

  • This weekend, a First Alert Weather Day warns of a significant winter storm likely in Middle Tennessee and Southern Kentucky, while the Tennessee Valley Authority says it executed a season‑readiness campaign to meet higher demand.
  • Since January 2024, Tennessee Valley Authority has added about 2,000 megawatts and 10 new natural gas units at Johnsonville to expand supply.
  • Upgrades at natural gas and coal sites reinforce equipment protection as TVA crews installed enclosures, improved insulation, and added heat‑trace monitoring systems sending real‑time data to control rooms.
  • Short-Term capacity increases reduce immediate outage risk as new natural gas units produce 530 megawatts, and 6,200 megawatts planned with 3,700 megawatts under construction power 2.1 million homes, TVA says.
  • TVA plans a multi‑year investment program with a $11 billion investment over the next three years to strengthen the grid and better meet surge demand, TVA says.
