U.K. electricity grid goes coal-free for first month since Industrial Revolution

first_img FacebookTwitterLinkedInEmailPrint分享The Guardian: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 record was possible, in part, because of the collapse of energy demand in the UK caused by the coronavirus lockdown and two bank holidays in a fortnight. But the chief reason was the unseasonably sunny spring weather, said Roisin Quinn, head of National Grid’s control centre.“Great Britain’s incredible coal-free run has continued throughout May, giving us the first full calendar month – 744 straight hours – of electricity generation without coal since the Industrial Revolution,” Quinn said.[Jillian Ambrose]More: UK electricity coal free for first month ever U.K. electricity grid goes coal-free for first month since Industrial Revolutionlast_img read more
