“At IPL, we’ve invested over $2 billion in ‘greening’ our generation portfolio and providing reliable and affordable energy to IPL customers,” the statement added.
Jackson joined AES as part of the DPL acquisition in 2011. Over the last seven years, Jackson has held numerous leadership positions prior to his current role as IPL and DP&L president and CEO, including DP&L chief financial officer.
“I am proud of all the accomplishments we’ve made together at AES over the past seven years,” Jackson said in the same statement. “It’s been an honor to serve the people of Indianapolis and Dayton and the surrounding communities by providing reliable and affordable energy.”
Jackson became DP&L CEO in February this year in another sudden leadership change.
At the time, DP&L announced a corporate restructuring in which AES Corp. cut 60 Ohio jobs and 100 jobs in Indiana.
Tom Raga, Jackson's immediate predecessor, became executive vice president of DPL Inc. in that leadership shift.
Jackson was not available for comment Thursday, said Mary Ann Kabel, a DP&L spokeswoman.
Kabel said the resignation had nothing to do with business conditions or behind-the-scene activity at the utility.
"This was a choice that Craig made, and we respect that choice," Kabel said.
Asked why the company has seen a change at the CEO position twice in less than a year, she said customers should be assured that DP&L leadership remains stable.
"We should feel very comfortable about the future," she said.
"We're going to start our search," she added. "We're going to look internal and external to the company."
DP&L owner AES, based in Arlington, Va., bought DP&L in 2011.
DP&L supplies power to 515,000 customers in 24 counties throughout west central Ohio.
