Wind farm

A variety of energy including low-carbon, nuclear, coal and gas.?

How does Blue for Business work?

  1. Energy sources
    Electricity is generated from a variety of sources, including low-carbon nuclear power.
  2. National Grid
    Electricity is then transmitted through the National Grid and through your local distribution network.
  3. Your business?
    Then we supply the electricity to your business.

We can't identify what particular type of energy generation source your electricity is coming from. That's why we match the electricity we estimate your business has used from a low-carbon source. For our Blue customers, that's nuclear.
