The first quarter of 2025 saw relatively few records broken on Britain’s power system. Wind and solar power both edged upwards in March, with wind producing more than 72% of demand on 30 March, and solar smashing its previous record of 10.7 GW by producing 12.2 GW on 18 March. Biomass had both a record daily output and record month in February, producing close to 3 GW averaged over the month.
