Providing renewable gas and electricity to Exeter since 2015.

Our Background

Gorst Energy is an anaerobic digestion (AD) facility located in Clyst St Mary, on the outskirts of Exeter. We process agricultural feedstocks supplied by local farmers, primarily pig manure and sustainably grown crops. Using high-quality AD technology, the feedstock is broken down to produce biogas and digestate:

  • The biogas is used to either generate and export renewable electricity to the National Grid, or upgraded and injected directly into the UK’s gas network. This green electricity and gas directly supplies local homes and businesses surrounding our Gorst Energy plant.
  • The digestate is high in nutrients and a good replacement for artificial fertilisers. It is used on all of the land that grows feedstock crops for our AD plants, reducing costs for farmers as well as decreasing their carbon footprint.

Gorst is essential in Exeter and East Devon’s journey towards a more local circular economy. We provide a sustainable solution that supports local businesses and powers our communities.

How we are helping Exeter and East Devon

Gorst Energy currently provides enough renewable gas to power 2,389 homes and renewable electricity to power 934 homes. This makes us one of the biggest renewable energy generators in the city of Exeter, something we are very proud of.

We’d like to do more

Our facility has the potential to contribute a lot more locally produced green energy by increasing the range of feedstocks available – we’re currently unable to make the best of our potential because of the limited quantity and types of feedstock (ingredients mixed in the process to produce the renewable energy) that we’re allowed to bring to the plant.

We would like to change this and have submitted a planning application that seeks to increase the tonnage and variety of feedstocks we are able to process.

This would enable us to further improve our sustainable output, in line with County and National policies targeted at increasing the production of renewable energy from waste. If successful, we can increase the supply of renewable electricity to 1,570 homes and renewable gas to 3,538.

Existing AD plant With proposed development (cumulative) % increase
Annual output gas (kW) 32,488,650 48,120,870
Average no. of homes supplied 2,389 3,538 48%
Annual electricity output (kW) 3,363,840 5,650,200
Average no. of homes supplied 934 1,570 68%
In addition to the generation of renewable gas and electricity, our plant is also helping to reduce CO2. Gorst Energy currently delivers carbon savings of 3,387 tonnes CO2e per year. This figure would be doubled to 6,774 tonnes CO2e per year if the proposed feedstock changes are made.
To put these figures into perspective, carbon emission calculations conducted by Exeter University to determine Devon’s carbon footprint estimate that the management of Exeter’s waste emits over 41,000 tonnes CO2e per annum. At 3,387 tonnes CO2e, Gorst Energy delivers a carbon saving equivalent to 8.2% of the carbon emissions associated with managing waste in the city, increasing to 16.4% should we be allowed to make the proposed changes. Against Exeter’s total carbon footprint, Gorst Energy achieves a 0.62% saving in carbon emissions, increasing to 1.2% post expansion.
We are very proud of our contribution to the reduction of greenhouse gases and provision of renewable energy to Exeter and East Devon and hope we are able to provide even more homes with green energy in the future.

Working with local farmers

“One of the advantages of working with Ixora, particularly for arable farmers, is that we can use maize as a break crop. This still enables us to grow our primary commercial crops like wheat and rape…another huge benefit is that the digestate saves us having to use artificial fertilisers and using an organic material instead (digestate) which is a far better replacement and we are getting better crops because of this.”
– Troy Stuart, Farmer supplying sustainable crops to Gorst Energy

Proud sponsors of Exeter Athletic RFC

“I’m delighted to be a part of such a strong local community both inside and outside of work. Ixora really is committed to promoting positive change across a range of causes and I’m proud to be a part of that”.
– Chris Jenkins, Regional Manager at Ixora and member of the club’s first team
