From , all our tariffs use 100% renewable energy and 100% green gas.

Using the power of falling water, the sun, the wind, and organic waste material, we provide energy that is 100% renewable.

Not only are our tariffs renewable, but they help to clean up and make use of waste products. Some of our generators even use pig poo, skip waste and used chip fat to make electricity!


Moving into 2017 - 2018 we will be keeping our 100% renewable energy and 100% green gas fuel mix and our best view of what the 2017-18 fuel mix will be (prior to OFGEM’s audit) is below:

48.13% Landfill Gas
23.08% Wind
18.23% Solar
9.2% Anaerobic Digestion
0.97% Hydro
0.39% Biogas

Amazing what comes from the back end of a pig (or cow)

How is it generated?

It’s generated in weird and wonderful ways. It’s fun to sell; that makes us happy.


Harnessing the British weather.

Hydro-electricity means taking the force of free-falling water and converting it into power. Some of our energy comes from small hydro-electric schemes in Scotland, Dorset and Cornwall.

Faichemard Farm


Energy from 93 million miles away.

A solar cell (or a ‘photovoltaic cell’ to you scientists out there) takes the light from the sun and converts it into power. ‘Solar thermal systems’ take heat from the sun and use it to heat water in our homes.



Love it or hate it we don’t use much of it.

Does what it says on the tin. Our suppliers use the force of the wind to drive turbines, which in turn make electricity.

RES Group


Plants to you and me.

Biomass is produced from organic material — that’s wood, plants and animal waste to you and me. We get this either directly from plants, or from waste products from industry, agriculture or your very own home!


Anaerobic digestion

Finally something useful from what comes out of the back end of a pig.

Anaerobic digestion — a process where microorganisms break down organic material in the absence of any oxygen to produce a methane and carbon dioxide-rich biogas. This can be burnt to produce energy, with none of the harmful effects of fossil fuels. And what’s more, the nutrient-rich solids left after digestion can be handily used as a fertiliser!

Gask Farm

Our electricity generators

Safe energy from sound sources.

Gask Farm

Gask Farm

The folks down at Gask farm have finally solved the problem of what to do with their pig manure. Turn it in to electricity! Pig slurry is fed into an anaerobic digester and the gas released is captured and burnt to generate electricity. The fertiliser produced as a by-product is used to feed the crops which are then fed to the pigs the following year. A real circle of life!

Faichemard Farm

Faichemard Farm

Highlands farmer Duncan Grant is taking advantage of a river running through his family farm by creating electricity from it. He has installed a micro hydro-generator and is selling the electricity to us.
