Susan M. Gray, who began her career at Tucson Electric Power as a student intern 26 years ago, will become CEO upon David Hutchens’ departure Jan. 1.

David Hutchens, president and CEO of UNS Energy Corp. and subsidiaries Tucson Electric Power Co. and UniSource Energy Services, will leave in January to head the company’s Canadian parent, Fortis Inc.

Susan M. Gray, president and chief operating officer of UNS Energy and its subsidiaries, will become CEO upon Hutchens’ departure Jan. 1, the company said.

Hutchens, who was named chief operating officer of Fortis last January, will become president and CEO of the company, succeeding the retiring Barry Perry.

Based in St. Johns, Newfoundland and Labrador, Fortis acquired UNS Energy in 2013 and also owns utilities in Canada, New York and the Caribbean, with 2019 revenues of nearly $9 billion.
