Great Britain's monthly electricity stats

Ever wonder how much electricity is generated and used in Great Britain?

Wind made up around 24% of the energy mix, with high winds on 24 May setting a new all-time record for wind generation at 19.916GW

May also saw 635 coal-free hours, with coal making up less than 0.1% of the generation mix this month.

Gas again topped the generation mix at 43.6%, up by 3.6% on the previous month, while imports continued to play a smaller role in the energy mix down to 2.4% from 5.1% in April.

Average carbon intensity across May went up slightly to 182 gCO2/kWh from 181gCO2/kWh in April, with the lowest point being 14:30 on 13 May 2022 with 51 gCO2/kWh.
