Great Britain's monthly electricity stats

How we generated electricity in May

In May, 44% of electricity came from zero carbon sources, peaking at 80% on 4 May at 11am. 

Gas was our largest source of fuel, with 34% of electricity being generated by gas. Wind was our second largest power source, attributing 19.6% of generation in May.

For the first time this year, 0% of generation came from coal in May, allowing us to achieve 560 consecutive hours without coal. This is a great step towards our ambition of delivering periods of 100% zero carbon operations by 2025 and a zero carbon electricity system by 2035.
