Great Britain has set a new wind generation record and it is a big one.

At 7:30pm on 11 November wind turbines were pumping out 22,711MW, beating the previous high of 22,523MW set in December 2024.

That is enough clean electricity to power more than 22 million homes.

Wind was delivering 43.6% of all power on the system which means three quarters of Britain’s homes were effectively running on wind alone.

It is the latest sign of how fast the clean power mix is shifting.

Wind and solar now deliver around 60% of Britain’s electricity which is a staggering jump from just 3% in the year 2000.

Britain now hosts five of the world’s largest offshore wind farms. In June the country also set a new solar record at 14GW which briefly supplied nearly 40% of the electricity mix.

The government wants to double onshore wind and quadruple offshore wind by 2030. Ministers also expect solar to grow two and half times by the end of the decade.

Wind has already become the UK’s biggest source of electricity. It generated nearly 83TWh in 2024 and pushed clean generation to a record high while cutting fossil fuel use and shrinking bills.

Kayte O’Neill, Chief Operating Officer at the National Energy System Operator, said:

“This is a world-beating record showing that our national grid can run safely and securely on large quantities of renewables generated right here in Britain.”

She added: “It really shows what is possible and I look forward to seeing if we can hit another clean energy milestone in the months ahead: running Britain’s electricity grid entirely zero carbon.”

The generation split on the night shows how dominant renewables have become.

Gas supplied just 12.5% while embedded wind delivered 12.1% and interconnectors added 11.3%.

Nuclear supplied 8% with biomass at 8% hydro at 1.4% and storage at 1.1%. It was a snapshot of a system edging closer to zero carbon operation.

For the grid it is a proof point. High renewable penetration works and the system can stay stable secure and clean at the same time.
