Overview
- Output peaked at 22,711 MW at 7:30pm on 11 November, surpassing the December 2024 high and equating to power for about 22 million homes, according to Neso.
- Wind supplied 43.6% of GB electricity plus 12.1% from embedded wind for a 55.7% total, with the rest from gas (12.5%), interconnectors (11.3%), nuclear (8%), biomass (8%), hydro (1.4%) and storage (1.1%).
- Neso says wind is now the UK’s largest source of electricity generation and has raised the prospect of running the grid for a period entirely on zero‑carbon power.
- Industry group RenewableUK urged ministers to increase the capacity offered in the next round of contracts to support more wind projects and private investment.
- The UK has about 32 GW of installed wind capacity split roughly evenly between onshore and offshore, and curtailment during the record half‑hour was minimal (£4.73 to switch off wind and £26.21 for replacement power) despite high constraint costs reported this year.
