Elexon has hired Simon McCalla as CEO following Mark Bygraves stepping down in November 2021.

McCalla is to work with chair of Elexon and of the Balancing and Settlement Code (BSC) Panel, Michael Gibbons, the non-executive directors and the executive team to lead the company during a time of "significant – and unprecedented – industry change”, the company said.

Meanwhile, Sara Vaughan, who has been interim CEO since November, is to return to her role as a non-executive director on the Elexon board once McCalla joins Elexon on 4 April.

Elexon said its board unanimously agreed that McCalla was the right candidate for the job and possessed the capabilities, skills and experience required.

"I believe Simon’s wealth of business experience, as well as his knowledge of digitalisation and data platforms, will help support us to continue on the path we are on, as well as bringing the skills needed to drive Elexon forward," Gibbons said.

He also praised Vaughan for her "short but impressive tenure", during which Elexon has continued to work on key strategic projects such as the cloud-based Kinnect platform, designed to reduce the risk of the performance of Elexon’s current systems deteriorating, and market-wide half hourly settlement.
