Our fuel mix

At Shell Energy, we believe everyone in Britain should be able to choose 100% renewable electricity for their home. That’s why it now comes as standard on all our tariffs.

Historical fuel mix

Every energy company needs to provide a fuel mix disclosure which shows the breakdown of electricity generation historically. The table below shows this for the period 01/04/2018 - 31/03/2019 including the time when we were trading under the First Utility name up until 25/03/2019.

Current fuel mix

100% renewable electricity for 100% of our customers. All our electricity now comes from renewable sources such as wind, solar and biomass.

Applicable from 25th March 2019

This is certified by Renewable Energy Guarantees of Origin (REGOs), which guarantees that for every unit of electricity you use, a unit of renewable electricity is put into the grid by renewable generators in the UK.

Why is this different?

The Fuel Mix Disclosure (FMD) is a retrospective reporting tool which measures the timeframe of 01/04/2018 - 31/03/2019 and is reported in October. As such our current mix reflects the period from April 2018 to March 2019. Previously, we didn’t buy REGO certificates which meant that the generation mix was a representation of the typical residual generation capacity in the UK (i.e the amount of energy that is available once REGO-match renewable generation is removed). As of 25 March 2019 every unit of electricity we provide to our customers is matched by a REGO certificate meaning our fuel mix is now 100% renewable.

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.
