EDF Fuel Mix

Every year we must publish details of the fuel sources that have been used to generate the electricity we supply to our customers. The information in the table below covers our supply licence for EDF Energy Customers Ltd for the period from April 2019 to March 2020.

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 Business, Energy and Industrial Strategy (BEIS). Depending on the tariff you are on, the fuel source and the carbon emissions associated with the generation of your electricity may vary.

Product table

(1) Nuclear: At the end of each fuel mix reporting year we’ll make sure we’ve have enough nuclear generation declarations to match the total volume of electricity supplied to all of our customers on zero carbon nuclear backed tariffs.

(2) Renewable: At the end of each fuel mix reporting year we’ll make sure we have purchased enough renewable electricity or allocated enough renewable energy guarantee of origin certificates to match the total volume of electricity supplied to all of our customers on tariffs labelled as renewable.

(3) Carbon balancing: At the end of each fuel mix reporting year we’ll make sure we have allocated enough carbon emission reduction certificates to completely offset any residual emissions identified in the ongoing operation of all our annual nuclear and renewable generation to bring net emissions to zero.

The zero-carbon 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.
