Highs winds over the weekend helped provide almost a quarter of the UK’s electricity supply, industry body RenewableUK said.
A new record of 24% was set for wind power as nuclear reactors remained offline and a large gas plant was hit suddenly by a fire.
The previous record of 22% of total generation was reached in August.
Wind power outperformed nuclear power, generating 7,998 megawatts (MW) during a 30-minute period on Saturday, according to National Grid statistics.
The figure is the equivalent of powering 17 million homes, based on average consumption in October.
RenewableUK’s director of external affairs, Jennifer Webber, said: “This year has seen successive new records for wind generation and this latest evidence shows it’s more than capable of stepping in when traditional sources of generation go offline without warning.
“As we can expect more of these outages in the future, it’s reassuring to know we have wind filling the energy gap.
“Wind power is often used as a convenient whipping boy by political opponents and vested interests; all the while, it’s been quietly powering millions of homes across the UK and providing a robust response to its vocal detractors”.
A sudden drop off in gas power was caused by a fire at Didcot B power station in Oxfordshire, which normally has a capacity of up to 1,360MW.
There are also currently four nuclear plants (nine reactors) which are currently offline due to unplanned outages and refuelling, removing 5,303MW of generating capacity from the system.
In Scotland,power generated from the wind reached a high last year, with levels more than five times higher than in 2006.
