Fuel Mix

Screenshot 2020-10-19 at 16.52.52.png

In 2019 npower became part of the E.ON group but it wasn't until June 2020 that we started to move npower customers onto our shiny new E.ON Next systems. As this fuel mix statement is for the year before any customers moved over to E.ON Next, it reflects the makeup of the electricity supplied by npower under their supplier licences from April 2019 to 31 March 2020.

With E.ON Next, all of the electricity we supply to your home is backed by 100% renewable sources, like wind, biomass and solar power. And where we don't generate it ourselves, we buy renewable energy certificates to show we've replaced what you used with 100% green electricity. So don’t worry, you’ll see all of this in our E.ON Next Fuel Mix statement next year. Or if you don’t quite believe us you can check out E.ON’s fuel mix statement for the same period.
