Welcoming this morning’s announcement by National Grid ESO that Great Britain’s wind farms generated a record 17.3 gigawatts (GW) between 1-1.30pm yesterday, RenewableUK's Deputy Chief Executive Melanie Onn said: 

"It's great to see our onshore and offshore wind farms have smashed another record, generating more power on a cold December day than ever before, just when we need it most. We expect to see many more records set in the years ahead, as the Government has made wind energy one of the most important pillars of its energy strategy for reaching net zero emissions as fast and as cheaply as possible. This new record is an early Christmas present we can all celebrate". 

This beats the previous record high of 17.1GW which was generated on Jan 2nd this year. 

When the new record was set yesterday, wind was generating 43.2% of Britain’s electricity.

National Grid ESO also stated this morning that 74% of the UK’s electricity was zero carbon (wind, nuclear and biomass) at the time they made the announcement. 

The highest percentage of GB electricity ever generated is 60%, set in the early hours of Wednesday 26th August (14.2GW).
