Increased output from wind farms saw renewables account for a record 47% of the UK’s total generation in the first quarter of 2020.
The share increased from 35.9% in the first three months of 2019, according to statistics by the Department for Business, Energy and Industrial Strategy (BEIS) show.
Renewable sites produced 40.8 TWh of electricity, up 29.8% in annual terms on the back of capacity additions, higher average wind speeds and increased rainfall volumes.
Output from offshore wind farms rose by 53% compared with the previous year, while onshore wind generation grew by a fifth.
In total, wind generated 30% of the UK’s electricity in the first quarter, beating the previous record of 22.3%.
Overall, low carbon electricity which also includes nuclear power, made up a record 62% of the generation mix, up from 52% for the same period the previous year, the figures show.
Coal’s share edged up from 3.5% to 3.8%, as stocks at Fiddlers Ferry power plant were used up before closing, while gas fell from 42% to 31%.
Industry body RenewableUK’s head of policy and regulation Rebecca Williams said: “At the coldest time of year, wind and renewables rewrote the record books right across the board, keeping our nation powered up when we need it most.
“This is the clean energy transition written very large indeed,” she said.
