EDF Energy Fuel Mix Disclosure


EDF Energy Fuel Mix Disclosure

All suppliers, including EDF Energy, are required to provide information about the mix of fuels they use to generate the electricity they supply to their customers. They also need to disclose the environmental impact of this fuel mix.

This information is known as the Fuel Mix Disclosure and is published annually.

Shown below are EDF Energy’s Fuel Mix Disclosures for the latest reporting year as well all years back to 2013/2014. We will update this page with the latest Fuel Mix Disclosures as they become available.


EDF Energy Fuel 2017/2018

The table below shows the EDF Energy Fuel Mix Disclosure for the period 1 April 2017 to 31 March 2018.

Energy SourceEDF EnergyUK Average
Source: EDF Energy
Coal7.55%7.64%
Natural gas9.39%41.24%
Nuclear71.21%20.01%
Renewables11.66%29.04%
Other fuels0.19%2.07%
CO2 emissions (g/kWh)104225
High-level radioactive waste (g/kWh)0.00500.0014

Compared to the UK average, EDF Energy supplies a much higher proportion of energy generated from nuclear – not a huge surprise as it is a significant generator of nuclear power. Consequently it supplies a much lower proportion of electricity generated from natural gas and renewables. Its CO2 emissions are well below the UK average largely due to low carbon emissions from nuclear power.

Compared to the preceding year, EDF Energy has reduced its supply of electricity generated from nuclear and increased the proportion generated from renewables.
