Fossil Fuels
Gas and fossil fuel electricity generation from NESO data.
The role of gas
Natural gas (mainly CCGT plants) is the UK's largest single source of electricity, providing flexible generation that ramps up when wind is low and down when renewables are abundant.
Coal phase-out
Coal generation has fallen dramatically in the UK, from 30% of electricity in 2014 to near zero by 2024. The UK plans to phase out coal power completely.
