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 01/04/2017 - 31/03/2018.
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.
First Utility fuel mix disclosure label
(relates to electricity supplied in the period April 2017 to March 2018)
|Energy Source||Our fuel mix (%)||Energy Source (g/kWh)||UK fuel mix (%)|
|High-level radioactive waste||-||0.007||-|
What is a Fuel Mix Disclosure certificate?
Every energy supplier is required to produce one of these certificates to show how the electricity we provide to our customers is generated. Outside the Big Six, the vast majority of suppliers don’t actually generate any electricity ourselves; we buy it from the market. And given that all the energy generation - whether it be solar, wind or gas powered - all goes into one big pot, we end up buying a representative mix of the UK’s generation.
That currently looks like this, with about 30% of all power coming from renewables:
|Energy Source||Fuel mix (%)|
So why does First Utility’s fuel mix disclosure look very different from this?
The Government has recently changed the way it calculates the Fuel Mix thanks to the emergence of what’s called a REGO, or Renewable Energy Guarantee of Origin. This catchily titled certificate allows those suppliers who bought one to match up every unit of renewable energy that goes into the grid, with a customer who uses it. Once you remove the amount of REGOs from the mix, you end up with the ‘residual mix’ i.e. the amount of renewable energy left over.
At First Utility we haven’t historically purchased REGO certificates, which is why our fuel mix now differs from the average generation mix.
Please note, figures are rounded
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 BEIS (details of these can be found at the BEIS website).

First Utility total emissions (g/kWh) are 355.4 based on our percentages. And the total nuclear waste is 0.001315165 g/kWh.
