Tennessee Valley Authority Will Build New Gas Plant; EPA Isn’t Happy

The EPA is not happy the Tennessee Valley Authority has decided to build a new natural gas plant to replace some of its coal generation

The TVA, America’s largest public utility, plans to retire the first of two coal-burning units at the Cumberland Fossil Plant near Cumberland City, Tennessee, by the end of 2026.

The proposed 1,450-megawatt natural gas plant would be up and running before then.

“The EPA issued a response to the analysis stating that TVA relied on “inaccurate underlying economic information” and “may continue to underestimate the potential costs of the combined cycle gas plant and overstate the cost of solar and storage,’” reports AP.

The agency also said that the TVA used a “misleading” metric to show that renewables are more expensive than natural gas generation and failed to consider the opportunities presented by the Inflation Reduction Act’s provision of $375 billion over 10 years for clean energy projects.

It is unclear if the EPA has suggested any physically or financially sound solutions to wind and solar’s intermittency and dispatchability problems.

TVA’s president and CEO Jeff Lyash said in a statement that:

“Replacing retired generation with a natural gas plant is the best overall solution because it’s the only mature technology available today that can provide firm, dispatchable power by 2026 when the first Cumberland unit retires – dispatchable meaning TVA can turn it off and on as the system requires the power.”
