ACES Names Michael T. Steffes Its President and CEO

May 3, 2024

ACES Board Chairman, Clifton Karnei, announced today that Michael T. Steffes has been appointed President and CEO of ACES, effective immediately. Steffes joined ACES in 1999 as Vice President of Marketing and Trading, and was promoted to Senior Vice President and Chief Operating Officer in 2002. Since the departure of ACES’ former CEO David Tudor in May 2013, Steffes has served as Acting President and CEO.

The ACES Board of Managers began the search for its next CEO following Tudor’s resignation. “The Board interviewed internal and external candidates as part of a thorough and deliberate process,” said Karnei. “It was important for us to find a candidate with a vision for the future of ACES that is aligned with that of its Members. Steffes has proven to be a strong leader within the organization. His achievements within the energy industry, along with his commitment to quality of service and standard of care, were crucial in our decision. The Board is confident in its selection and is certain ACES will continue to prosper.” Steffes offers a unique level of management experience in energy trading, having held executive positions with Pennsylvania Power & Light, Valero Energy and Hadson Gas Systems.

Steffes commented, “I am grateful and humbled by the Board’s decision to entrust me with this responsibility. ACES has never been defined by any one individual. Our team is experienced and capable and will continue to provide quality service to our Clients. The success of those we serve ultimately defines the success of ACES.”
