Where does our electricity come from?

This is where we publish our Fuel Mix – to show where our electricity comes from. We are required by Ofgem to disclose our fuel mix, figures for the period 1 April 2020 to 31 March 2021 are as follows:


Renewables: 88.17%, Natural Gas: 9.29%, Coal: 0.81%, Nuclear: 1.06%, Other: 0.67%.

Figures include the purchase of GoOs (EU Guarantees of Origin) renewable certificates.


What is the renewable source breakdown?

Our Renewable products provide electricity from a blend of renewable sources and are backed by origin certificates.

Thermal: 40.01%, Wind: 23.88%, Hydropower: 19.52%, Solar: 16.59%.


Environmental impact of energy sources relating to our fuel mixes, and displayed on other websites:
All energy sources have some impact on the environment, but to varying degrees. As the net zero transition and the shift to natural renewable energy sources (wind, hydropower and solar) convey – there’s a need to move away from fossil fuels (e.g. coal, oil and natural gas), which do substantially more harm than renewable sources.

So what are the kinds of environmental impact energy sources can have?
Impacts are far ranging and can include air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. The intensity of the impact, as well as the type of impact, depends on the specific technology used, the location of the energy assets , and a number of other factors.
