Hello

Our fuel mix

All energy companies are required to tell their customers about the mix of fuels they use to generate the electricity and the impact this has on the environment.

The table below shows how we produced electricity from 01/04/2016 – 31/03/2017.

We keep the figures on this page updated in line with the publishing dates of the Government's fuel mix data disclosure data table, as defined in the Electricity (Fuel Mix Disclosure) Regulations 2005.
