National Energy System Operator Limited Overview
Pro stress-test →NESO is the National Energy System Operator for Great Britain, moving power around the country to keep homes and businesses supplied with energy 24/7, 365 days a year. NESO began operating on 1 October 2024 after the UK government acquired the electricity system operator division of National Grid plc for £630 million. Designated as the Independent System Operator and Planner (ISOP) under the Energy Act 2023, the organization plays a critical role in facilitating Great Britain's energy transition to net zero.
Strategic Profile
Pro stress-test →NESO is a private company limited by shares that is wholly owned by the Secretary of State, operating as a not-for-profit entity licensed and regulated by Ofgem and funded through energy bills. It carries out electricity system operator functions in Great Britain and balances the electricity system in real time so that supply meets demand. It has strategic planning roles for electricity networks, and planning and forecasting roles for gas transmission systems, positioning it at the center of Britain's energy decarbonization.
