Great Britain’s electricity network upgrade could cost nearly £90 bn by the 2030s, a 50% rise over prior estimates
Executive summary: The electricity system operator said the cost to rewire Great Britain’s network through the 2030s has risen by 50% and could reach almost £90 billion. The figure signals the scale of investment required to deliver clean power while meeting higher demand, affecting public finances, energy prices and industrial competitiveness.
Who is involved: Great Britain’s energy system operator, Labour government, Transmission and distribution owners, Consumer and business electricity users
Likely next: Government will set out a detailed investment roadmap and funding plan, Regulators may review cost‑recovery frameworks and price‑control settings, Market participants will assess opportunities for construction, engineering and green‑finance providers
The nation’s energy system operator has revised upward the forecast for rewiring the grid to meet clean‑power targets and rising demand, citing a 50% increase since the Labour government took office. The projected £90 billion outlay would span the 2030s and entail substantial spending on transmission, distribution and associated infrastructure. While the estimate reflects the scale of the decarbonisation challenge, it also raises questions about funding mechanisms and the impact on consumer bills.
