DTE Energy announces new chief information officer

Ambrose will be responsible for securing, operating, and applying the company's information technology assets toward achieving the company's strategic objectives

Detroit, May 17, 2011 — Steven B. Ambrose has been named vice president and chief information officer at DTE Energy, effective June 1, 2011. He replaces Lynne Ellyn, who has announced her retirement.

Ambrose will be responsible for securing, operating, and applying the company's information technology assets toward achieving the company's strategic objectives.

Ambrose has been with DTE Energy for 13 years, most recently as director for enterprise performance management. He also has served as director of information technology for the company's non-utility businesses. In addition, Ambrose has served as the chief-of-staff to president and CEO Gerry Anderson, providing support for key enterprise initiatives.

Ambrose earned an MBA with high distinction from the University of Michigan, a project management professional certification, a master's certificate in management information systems from the University of Southern California, and a bachelor's degree in business administration from Bellevue College.

Ellyn has served as CIO since 1998, and has led DTE Energy's IT organization to outstanding levels of performance. She was instrumental in successfully integrating the Detroit Edison and Michigan Consolidated Gas Co. IT organizations following the merger of the two companies in 2001. She also has been a utility industry leader in the areas of emerging technology and cyber security.

"Lynne has made significant contributions to DTE Energy, as well as to the IT and utility industries as a whole," said Anderson.

"While we'll certainly miss her leadership and expertise, I also have full confidence in Steve, who has significant experience in the field and is an extremely capable leader."
