Executive Team

Mike Steffes

President & Chief Executive Officer

“Our primary focus is to help our Members and Customers manage their energy cost and risk more efficiently. We continually anticipate what risks they will encounter, and collaborate with them to effectively manage those risks.”


Senior Vice President & Chief Financial Officer

“We devote significant resources at ACES to analyzing and verifying energy market settlements statements and invoices, one of the many activities for which I am responsible. We have developed detailed processes that ensure that our Members’ and Customers’ energy transactions are financially settled accurately.”


Senior Vice President & Chief Risk Officer

“Because there are so many inherent risks in an energy supply portfolio, and because market conditions can change so quickly, Energy Risk Management is a never-ending process. It’s like the advice you give a batter at the plate – never take your eye off the ball.”
