Our fuel mix

Unicom is proud to provide 100% renewable electricity. Our 100% Renewable Electricity Tariff is backed by renewable energy sources, including wind farms1.

As an electricity supplier who cares, we are keen to do our part to sustain and protect the environment. We know that non-renewable energy sources are having a negative effect on our planet so we are looking to do our bit, by helping our customers do their bit.

How is Unicom a 100% renewable electricity provider?

For every unit of electricity that our customers who have chosen our 100% Renewable Electricity Tariff use, we match this by purchasing a renewably sourced unit, directly from the biggest offshore wind energy company in the world, Ørsted. We do this by taking part in the Renewable Energy Guarantees of Origin (REGO) scheme – more on this below.

By switching to 100% Renewable Electricity, based on average consumption, a typical Unicom customer will save 2.08 tonnes of CO2 from entering the atmosphere…2

How do REGOs work?

Our Energy regulator Ofgem issues one REGO certificate per megawatt hour (MWh) of eligible renewable output to generators of renewable electricity. This shows that a given share of energy was produced from renewable sources. We then purchase these certificates from Ørsted to match the amount of electricity our customers use and the amount of electricity from renewable sources that is on the grid.
