Our fuel mix

wind turbines and solar panels

Where does our energy come from?

At Bristol Energy we offer the greenest electricity we can, at the best price we can. And we're helping Bristol to tackle social and environmental challenges such as fuel poverty and climate change – so you can go green, and give back.

Overall our fuel mix for the period between April 2018 and March 2019 was 79% green.

The UK average is 32.8%, so we’re pretty proud of this. Despite being just over three years old, we’re already well above the national average. And we’ll get greener as we grow, by supporting renewable generators.


Want to go even greener?

As you’d expect, you get 100% renewable electricity on our My Green Plus tariff and our Green tariff for businesses. We get this from independent generators across the UK, from local businesses, to farmers and community energy projects up and down the country.

For every unit of renewable energy, we also purchase REGO certificates, which are issued by Ofgem and allow us to trace, and prove, where that unit of renewable energy comes from. This way, you can be sure that what you are getting is what we say it is.

And we have a Green tariff for businesses.

What does that mean for you if you’re not on a green plan?

If you’re on one of our other plans, you get more renewable electricity than the national average. And a commitment that we’ll get greener as we grow.

If you’re a generator interested in partnering with us, we offer Power Purchase Agreements at competitive rates, a fresh approach to doing business, and the great service you expect.

What is our environmental impact?

As we get greener, our carbon emissions will get lower too. But we are pleased to say these were also below the national average for the year 2018 to 2019.

Carbon Dioxide Emissions

Bristol Energy - 76 g/kWh

National Grid Average – 208 g/kWh

Radioactive waste?

As we buy more renewables direct from our generators, we’re able to buy less power from the National Grid, which means the amount of radioactive waste we produce comes down too.

High-Level Radioactive Waste

Bristol Energy - 0.00028 g/kWh

National Grid Average - 0.001309 g/kWh
