The UK’s electricity system recorded its “greenest” ever month in May after running without coal-fired electricity for a full calendar month. The National Grid, the energy system operator, said the country’s sunniest spring on record helped generate enough solar power to reduce the carbon intensity of the grid to its lowest level ever recorded. The bright and breezy weather helped wind and solar power make up about 28% of Britain’s electricity last month, narrowly behind gas-fired power generation, which made up 30% of the energy mix. Meanwhile, the record low demand for electricity during the coronavirus lockdown has left little room for the UK’s last remaining coal power plants to play a role. Since April the UK’s electricity system has run without coal-fired power for about 54 consecutive days, which has helped the carbon intensity of the electricity grid fall to the lowest average carbon intensity on record at 143 grams of CO2 per kilowatt-hour. The lowest carbon intensity ever was recorded at 46g CO2/kWh on Sunday 24 May.

With no coal on the grid and surging renewables, May was the greenest month ever on Great Britain’s electricity grid. Over the course of the month, the average carbon intensity of the electricity network was just 143gCO2/kWh. The lowest ever carbon intensity was recorded on Sunday 24 May, falling to just 46gCO2/kWh in the afternoon according to National Grid ESO. This was driven by the weather, with May setting a new record as the sunniest month on record with 266 hours of sunshine, according to the MET Office. This beat the previous record set in June 1957, when there was 265 hours of sunshine.

Britain’s electricity mix was its greenest on record last month as sunny weather and low power demand during lockdown left no need to burn polluting coal. National Grid said that solar power had provided a record high of 11.5 per cent of electricity generation in May, in what the Met Office has said was the sunniest-ever calendar month. No coal-fired power plants were used during the entire month, the first time that has happened since Britain began generating electricity from coal in 1882. The “incredible coal-free run” stands at 53 days and counting, National Grid said yesterday.
