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 2024 to March 2025.
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.

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.

Product table
(1) Zero carbon: Zero carbon tariffs and products include any sold as ‘nuclear backed’, such as Zero Carbon for Business (formerly Blue for Business).
(2) Renewable: All renewable tariffs and products.
(3) All other: All other tariffs and products - tariffs not referred to as Zero Carbon or Renewable.
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.
