"‘Misleading’: EPA lambasts TVA analysis for Kingston methane project

...EPA says solar would be ‘lower cost’, safer

TVA says that building a gas plant would be cheaper. EPA rejects this claim, which TVA made without disclosing its math, reminding the federal utility of its legal requirement to use “least-cost planning.”

“To meet TVA’s identified mandate, TVA should consider lower cost, lower risk, and more responsible alternatives that are viable,” EPA wrote, such as using a solar and storage system or a blend of renewables with a smaller amount of gas.

An independent study by the Applied Economics Clinic showed that the solar option proposed by TVA could save customers $1.3 billion over 20 years compared to the gas plant."
