EDF Fuel Mix
Every year, we must publish details of the fuel sources used to generate the electricity we supply to our customers. The information in the table below covers our supply licence for EDF Energy Customers Limited from April 2025 to March 2026.
Our customers' electricity is sourced from our own UK power stations, the wholesale energy market and other independent power generators. We are a major supporter of independent renewable generators.
| Coal | Gas | Nuclear | Renewable | Other | CO2 g/kWh | Radioactive waste g/kWh | |

The figures for the UK average fuel mix are provided by the Department for Energy Security & Net Zero (DESNZ). Depending on the tariff you are on, the fuel source and carbon emissions associated with the generation of your electricity may vary.

The nuclear backed and renewable electricity that we buy for Residential, SME, Zero Carbon for Business (formerly Blue for Business) or Renewable tariffs and products is supplied into the National Grid. Customers receive that electricity through the National Grid, not directly from zero-carbon generators.
