US-based electricity grid operator PJM Interconnection has appointed Terry Boston as its new president and CEO.

Mr Boston has earlier served as the executive vice president of power systems operations at the Tennessee Valley Authority (TVA). He was responsible for TVA’s transmission and power supply network of 17,000 miles of transmission infrastructure.

He will assume the post held on an interim basis by Karl Pfirrmann, who will serve as PJM’s executive vice president.

Howard Schneider, PJM’s chairman, said: We’re fortunate to have an executive of Terry Boston’s caliber, whose extraordinary career at the nation’s largest electricity wholesaler and public power provider has prepared him extremely well to lead PJM into the future.
