Nothing is ever as simple as it seems when it comes to TVA and its management. What is clear is that three TVA board members whose terms expired in May 2016 were not confirmed by the U.S. Senate and, therefore, they go off the board on Jan. 3, 2017. They are the current chair Joe Ritch, along with Mike McWherter and Peter Mahurin.
The bylaws do not provide for a vice chair or someone to fill in for a vacant chair position immediately, which will occur in one week. The chair of the audit committee, who is Lynn Evans, will preside at a called meeting and likely would be chosen to be chair, but she is not chair until elected. The bylaws further provide that the board should decide within 30 days of the vacancy who the next chair is.
