The CEO of the nation’s largest public utility plans to retire by September after nearly six years.

The nation’s largest public utility is moving ahead with a plan for a new natural gas plant in Tennessee despite warnings that its environmental review of the project doesn’t comply with federal law.

The largest public power company in the United States is launching a program to develop and fund new small modular nuclear reactors as part of its strategy to dramatically reduce greenhouse gas emissions.

This photo provided by the Tennessee Valley Authority shows CEO Jeff Lyash. On Wednesday, April 8, 2020, President Donald Trump took a swipe at Lyash's compensation, suggesting the executive's pay was too high. Trump had already been complaining about a vote to close a TVA Kentucky coal plant, which predated Lyash. Trump grumbled again in April about Lyash's compensation for running the independent agency, which makes him the highest-paid federal employee. During that Aug. 3 meeting, Trump received a note from chief of staff Mark Meadows that said Lyash had called the White House promising to address the labor concerns.
