Duke Energy Corporation has appointed Joyce Mullen to its board of directors with effect from 28 September 2026. She joins the audit committee and the operations and nuclear oversight committee, and her initial term runs to the 2027 annual meeting.
Mullen is executive vice president, strategic development at Insight Enterprises, an advisory role she took up after retiring as the technology solutions group's president and chief executive in April 2026. Before Insight she spent twenty one years at Dell Technologies across sales, operations, supply chain, partner strategy, services delivery and logistics, and earlier held roles at Cummins Engine Company. She is also a director of The Toro Company.

Harry Sideris, Duke Energy's president and chief executive, framed the appointment around the pace of change rather than the sector. "Joyce's experience as a transformative leader will help us further accelerate how we shape the future of energy," he said.
Ted Craver, the independent chair of the board, was blunter about the moment. "Her perspective will be incredibly valuable as Duke Energy navigates a pivotal time for both the company and the broader industry," he said.
The appointment lands while the sector is absorbing a step change in demand. Load growth driven by data centre construction has turned capital planning from a maintenance exercise into a question of how fast a utility can build, and the directors most useful in that conversation are not necessarily the ones with the longest power sector records.
What the committee assignments reveal
The committees she has been given say more than the biography does. Seating a new director on the audit committee immediately is a signal of confidence in financial literacy, and Mullen's twenty one years at Dell included supply chain and services delivery rather than only sales, which is the operating exposure that makes an audit seat useful rather than ornamental.
The operations and nuclear oversight committee is the more interesting placement. Utilities with nuclear fleets carry a category of operational risk that does not resemble anything in enterprise technology, and a director without a power background is not there to second guess reactor operations. What she can do is press on the parts of a large utility's operating problem that are now genuinely technological: load forecasting under data centre demand growth, grid instrumentation, the systems integration involved in large capital programmes, and the supply chain for long lead equipment. Those are the constraints that decide whether a utility's capital plan is deliverable, and they are closer to twenty one years of Dell supply chain and services work than a utility board's usual recruitment pool reaches.
