Sideris will replace Lynn Good. She is retiring from her role as CEO April 1 after serving at the company for more than two decades, including nearly a dozen years as CEO. Good was also the rare female leader of a Fortune 500 company.

Duke Energy (NYSE:DUK) said Monday its board appointed current President Harry Sideris as its new President and CEO effective April 1, succeeding Lynn Good, who will retire from her management and board roles at the company.

The 65-year-old Good, who is the first female to lead the Charlotte-based utility, will step down April 1. She’s being succeeded by Harry Sideris, 54, an employee of the company for 29 years who was promoted to president less than a year ago.
