EDF Energy 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 2018 to March 2019. 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.

(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, 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.
