Western Power managing director Doug Aberle has announced he will step down from the power utility after almost 40 years of service.
“He has led the organisation through a long journey of consistent improvement on all of its principal measures, and he has ensured there is a solid platform for that journey to continue into the future,” Mr Barnaba said in a statement.
Mr Aberle said he would focus on other avenues in retirement.
“Last year, I felt that I could essentially spend all of my active working life in this business and that if I didin’t leave with some years of high energy I would miss other opportunities that I have wanted to pursue,” he said.
Western Power corporate services general manager Paul Italiano will take the reins as acting chief executive in the interim.
