What does “fuel mix” mean?
A supplier’s fuel mix shows the sources of the electricity that it supplies to its customers e.g. coal, gas, nuclear and renewables.
Over the course of a year, energy suppliers must purchase sufficient electricity to feed into the national electricity grid to cover the amount their customers take out. At the end of each year, suppliers must disclose their fuel mix to the electricity and gas regulator, Ofgem. This information is published annually to help consumers make informed choices about their electricity supplier.

Fuel Mix Data
Carbon Dioxide Emissions (g/KWh): The weighted average of the carbon dioxide emitted in the production of electricity from each fuel source. This is calculated on the basis of figures provided by BEIS (details of these can be found at the BEIS website).
Radioactive Waste (g/KWh): The radioactive waste, being fuel burnt in the reactor to be subsequently discharged as spent fuel. This is calculated on the basis of figures provided by the DECC (details of these can be found at the BEIS website).
