In one day in February, almost 80% of electricity came from zero carbon energy sources, National Grid ESO has said.
The latest data shows that last month, 47% of electricity came from zero carbon sources.
National Grid ESO has said gas became the largest source of power generation in February, with 33.2% of electricity being generated by gas.
Wind generation followed, contributing 31% of the total generation.
The report suggests in February, just 1.8% of generation came from coal – this compares to February 2017, when coal accounted for 10.8% of generation.
The energy system operator added that the UK’s grid also achieved 73 consecutive hours without coal in February compared to 18 consecutive hours in January.
