UK onshore and offshore wind farms hit a new generation high of 14.9GW between 6pm and 6.30pm local time on 28 November, according to figures from the National Grid highlighted by RenewableUK.
The previous record was 14.5GW, which was set on 9 November.
Overall on Wednesday, wind generated 32.2% of the country’s electricity, more than gas which provided 23.5%, while nuclear supplied 17.9%, coal 8.7%, biomass 8%, imports 7.8% and hydro 1.7%.
Wind continued to dominate UK generation on the following day accounting for 32% of electricity produced, followed by gas at 25.0%, with nuclear supplying 18.1%, coal 9.1%, biomass 7.1%, imports 5.9%, and hydro 2.0%.
R-UK executive director Emma Pinchbeck said: “It’s great to see British wind power setting new records at one of the coldest, darkest, wettest times of the year, providing clean energy for people as they came home, switched everything on, turned up the power and cooked dinner.
“As well as tackling climate change, wind is good for everyone who has to pay an electricity bill, as the cost of new offshore wind has fallen spectacularly so it’s now cheaper than new gas and nuclear projects, and onshore wind is the cheapest power source of all.”
