Electricity rates for Tennessee Valley Authority customers will not be increased in the coming fiscal year. TVA’s board of directors voted Thursday to approve an $11.2 billion budget for the upcoming fiscal year that begins Oct 1 and does not include any rate hikes. TVA chief executive officer Tom Kilgore also announced at the meeting that he will be retiring. TVA’s board of directors appointed Kilgore as CEO in 2006. Kilgore, who said he was in the fourth quarter of life and wanted to pursue other things, said he preferred to leave in four to six months but would wait until the board appoints his successor.
