Great British Grid needs added delivery capacity to unlock investment, Savills says

By Public Technologies
  • Great British Grid could unlock investment and accelerate electricity connections if it expands delivery capacity rather than reallocating stretched resources.
  • Contracted connection demand rose from 41 GW in November 2024 to 125 GW in June 2025, roughly 2.7 times 2025 peak demand.
  • Scotland’s cross-border grid bottleneck cost around £800,000 daily in 2026/27, double the 2025/26 level, with bill payers bearing the expense.
  • The publicly owned company could lower infrastructure costs through cheaper capital, competitive bidding and early supply-chain commitments.
  • Supply-chain constraints, skills shortages and planning delays remain barriers; its role alongside existing network owners requires clarification.
