The National Energy System Operator (Neso) raised its forecast for grid buildout in the 2030s to £89bn, a 50 % increase on the £58bn it initially estimated in 2024, and now includes 43 network projects — 16 of them entirely new recommendations — to connect low‑carbon generation and meet rising electricity demand from data centres. The updated figure aligns with the government’s 2030 clean power action plan, under which targets require doubling onshore wind, tripling solar and quadrupling offshore wind capacity by the end of the decade.
