Beyond 2030 - Electricity Transmission Update Report
The National Energy System Operator (NESO) was created as a result of the UK’s 2023 Energy Act, an act that paved the way for Great Britain's journey to cleaner energy.
NESO published Beyond 2030 in March 2024, setting out a national view of the electricity transmission network Britain needs in the 2030s. On 30 June 2026, NESO published an update to that work. The update explains what has changed, what has not, and how updated evidence affects near‑term transmission decisions for Ofgem to consider.
Guy Jefferson, Transmission Managing Director at SP Energy Networks said: “SP Energy Networks is investing £12 billion in the transmission network across central and southern Scotland, upgrading the electricity system, boosting jobs and the economy.
“NESO’s update gives further certainty around the country’s future electricity grid and its potential to unlock billions in investment; giving businesses and supply chains the confidence to scale up and deliver.
“A fit for purpose modern electricity grid not only supports the UK’s ambition of being a clean energy superpower as it capitalises on its natural resources but also brings real benefits to communities — from new jobs and apprenticeships to improved local infrastructure.”
