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 2020 to March 2021. Our fuel mix for period April 2021 to March 2022 will be published on 1 October 2022.

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.
