Lynn Good has been elevated to president and CEO of Charlotte, N.C.-based Duke Energy, the largest U.S. electric utility. Formerly executive vice president and chief financial officer, she succeeds James Rogers, who remains chairman until December, when he is set to retire. Good is one of eight women CEOs of the 200 U.S. investor-owned utilities. She also was group executive and president of Duke Energy's commercial businesses group, responsible for Midwest non-regulated generation, international and renewables work.

The succession is part of the firm's November 2012 settlement with the state utilities commission over its mishandling of a $32-billion merger with utility Progress Energy last year, says a published report. Rogers became president and CEO in 2012 after the surprise ouster of William D. Johnson, who was linked to a problem-laden repair of the Crystal River, Fla., nuclear plant owned by Progress. Johnson, who was running Progress at the time, had been set to be Duke Energy's CEO as part of the deal. He has since joined utility TVA as CEO. In February, Duke Energy said the plant will be decommissioned. The utility will name a new chair-elect.
