The first day back to work after the New Year saw Britain\u2019s highest electricity demand in nearly a decade. Widespread snowstorms closed hundreds of schools<\/a>, as the UK recorded its coldest night of the year with temperatures plunging to\u00a0-12\u00b0C. With heating systems working flat out to keep homes warm, national\u00a0electricity demand peaked above 50 GW for the first time since 2018. Overall\u00a0demand across the quarter was 0.7% higher than a year ago, continuing its\u00a0recent upward trend.<\/p>\n\n\n\n

The extra demand was met largely by renewables rather than fossil fuels. A stormy\u00a0three months gave wind farms their most productive quarter ever, generating\u00a030% more electricity than during the same period last year. For the fourth\u00a0consecutive quarter, wind power was Britain\u2019s largest source of electricity.<\/p>\n\n\n\n

This pushed fossil-fuelled generation down by 16% year-on-year, while electricity\u00a0exports almost doubled. Only six days during the quarter saw fossil fuels produce\u00a0more electricity than low-carbon sources. This helped the carbon intensity of\u00a0electricity fall to an average of 127 g\/kWh over the three months to March, its\u00a0lowest ever level for a first quarter of the year.<\/p>\n\n\n\n

(1) Other sources give different values because of the types of plant they consider. For example, Energy Trends<\/a> records an additional 0.7 GW of hydro, 0.6 GW of biomass and 3 GW of waste-to-energy plants. These plants and their output are not visible to the electricity transmission system and so cannot be reported on here.<\/em><\/p>\n\n\n\n
