PJM’s promotion of Andy Ott to replace retiring CEO Terry Boston has prompted a series of additional organizational changes and promotions effective July 8.

Ott, formerly executive vice president of markets, becomes CEO-elect.

Mike Kormos, formerly executive vice president of operations, was promoted to executive vice president and COO. His deputy, Mike Bryson, formerly executive director of system operations, will become vice president of operations.

Ott’s deputy Stu Bresler, formerly vice president of market operations, becomes senior vice president of market services.

“It was Andy’s chance to put his [stamp] on the organization,” Boston said of the changes in an interview on Monday at the Mid-Atlantic Conference of Regulatory Utilities Commissioners in Williamsburg, Va.

Boston said the changes were largely prompted by the desire “to get Stu Bresler in place to run the markets” as Ott takes on more travel. “I told [Ott], ‘You think you do a lot of traveling now, you haven’t seen anything yet.’”

PJM’s settlements unit, formerly overseen by Bresler, is moving to the RTO’s financial group to ensure more independence.

Bryson’s responsibilities will increase as Kormos takes on a new direct report in Denise Foster, vice president of state and member services, who formerly reported to Ott.

In addition, Nora Swimm was promoted to senior vice president of corporate client services, from vice president of human resources and corporate client services, and Thomas O’Brien was named vice president and chief information officer, from vice president of information and technology services.

Boston said Swimm is taking on responsibilities for physical security while O’Brien’s new title was to recognize the expansion of his role in recent years, in which he has served as CIO without the name and PJM has begun dealing with cyber threats.
