Michael Desselle, SPP vice president and chief compliance and administrative officer, is retiring after 18 years with the RTO and 40 in the industry. His departure will be effective Jan. 2. 

“We’ll definitely miss Michael,” SPP CEO Barbara Sugg said in a Sept. 30 statement. “His dedication to SPP is clear. He’s respected by his peers, as exemplified by his service as chairman of the Board of Directors and CEO of the North American Energy Standards Board. We wish him the best in his well-deserved retirement.” 

Mike Riley, SPP senior director and deputy general counsel, has been promoted to vice president of corporate services and chief compliance officer to fill Desselle’s position. He begins a transition period Oct. 1. 

Attorneys Tessie Kentner and Chris Nolen have been named associate general counsels with Riley’s promotion.
