Be part of the clean energy movement

The project was initially designed to generate enough renewable energy to power its wastewater treatment site but, by the time planning consent was granted, a number of other on-site electricity generation initiatives meant the company was already self-sufficient.
We were able to work quickly and effectively with Wessex Water to complete the deal and built the project on site. Just 13 months later, the four turbines commenced generation for the first time – now generating enough clean electricity to power the equivalent of 5,232 average UK homes every year. Find out more about our Avonmouth wind farm here.

Located in the industrial area of Avonmouth, Bristol, we bought the rights to an 8.2MW wind farm from GENeco, owned by Wessex Water.

We worked with Wessex Water to acquire a four-turbine wind farm in our home city of Bristol. 

Unleashing the power of onshore wind

Avonmouth case study

Capable of generating over 7,000MWh of clean electricity a year, the equivalent of powering more than 2,000 average Scottish homes [2], the 2.5MW community turbine will deliver over 3,000 tonnes of carbon emissions reductions annually [3].  
This is the first project to be funded by Community Energy Catalyst (CEC), Thrive’s joint venture with Better Society Capital. Thrive initially provided a £4 million loan to Attix CIC in 2023 to fund construction and operation and this was transferred to CEC in July 2025. 
Now operational, Kilbirnie wind turbine will directly benefit local causes, with all profits from electricity sales going into Radio City’s programme of sustainable development projects that address the need for capital investment in a new Employment Hub, offering employment and training opportunities for local people, improve sustainable transport opportunities and help to address health and educational inequalities locally, as well as upgrading local sports and recreational facilities [4]. 
It will also support the charity’s ongoing work to address the substantial fuel poverty in its community through assistance with energy vouchers, distribution of halogen heaters and electric blankets, as well as and one to one advice to combat and reduce peoples’ energy bills.

This watershed moment for community energy follows the UK Government and Great British Energy publishing its Local Power Plan this month, aiming to invest £1 billion in locally owned clean energy projects and ensure communities directly benefit from the schemes they host [5].

The collaborative approach to funding the wind turbine provides a blueprint for financing the community-led energy transition from the ground up. It brings together £5.6 million in blended finance – £1.6 million in social investment from Social Investment Scotland and £4 million from Community Energy Catalyst. Local Energy Scotland supported the project through planning and design with a loan from the Scottish Government’s Community and Renewable Energy Scheme (CARES). The project has also received a combination of Great British Energy and Scottish Government grant funding via CARES.

[1] The project operates on a ‘merchant’ basis selling electricity on a purely commercial basis, without government price support mechanisms such as Contracts for Difference or historic Feed-in Tariffs. 
[2] Calculated using the most recent subnational statistics from the Department for Energy Security and Net Zero (DESNZ) showing that average domestic household consumption in Scotland is 3,429.3kWh per annum. 
[3] Carbon reduction is calculated by multiplying the estimated annual generation (7GWh) by the number of tonnes of carbon which fossil fuels would produce to generate the same amount of electricity. We have used DESNZ’s “all non-renewable fuels” emissions statistic of 448 tonnes of carbon dioxide per GWh of electricity supplied from the Digest of UK Energy Statistics (July 2025) Table 5.14 (“Estimated carbon dioxide emissions from electricity supplied”). 
[4] ATTIX CIC is a Community Interest Company established, and asset locked to Radio City Association Ltd to develop the community turbine in Kilbirnie. 
[5] According to its recent strategic plan, Great British Energy (GBE) plans to support over 1,000 community energy groups to take a stake in the UK energy transition.

Landmark community project in Scotland, which Thrive helped fund, is now generating clean energy locally, creating blueprint for national rollout. 

Kilbirnie community wind turbine enters commercial operation

Having provided the first commercial funding for United Downs in 2020, followed by further investment in 2023 and 2025 to complete construction, we’re really proud to see the landmark project come to life.  
The project is owned and operated by Geothermal Engineering Limited (GEL) and will provide 24/7 home-grown baseload power, helping to boost energy security by reducing our reliance on imported balancing power to complement wind and solar. 
In another UK first, GEL has started commercial scale production of sustainable lithium carbonate, the key raw material used in the production of rechargeable batteries, including those that power electricity vehicles and energy storage systems. From its February 2026 starting point, United Downs has the capacity to produce 100 tonnes per annum.

The well at United Downs that produces the geothermal fluid for power and lithium is over 5km deep – the deepest well ever drilled on UK soil. It taps into water exceeding 190°C &#8211; the hottest recorded in the UK. After power generation, the fluid is processed to produce technical grade lithium carbonate before being reinjected back underground. The water brought to the surface contains over 340 parts per million (ppm) of lithium, making it one of the highest concentrations found in any well to date in the world. GEL aims to scale its production to over 18,000 tpa over the next decade, enough for circa 250,000 EV batteries a year – 65% of the UK’s 2024 Battery Electric Vehicle (BEV) registrations. 
GEL has two other sites currently under development in Cornwall, which will deliver a further 10 MW of base-load geothermal power in the UK by 2030. The British Geological Survey has calculated that more than 200 GW of baseload (24/7) electricity could be produced from onshore geothermal sources. That is the equivalent of over 100 nuclear power stations.

Cornwall Time Lapse

The landmark project in Cornwall will also deliver the UK’s first commercial scale sustainable lithium.  

UK generates first ever geothermal electricity at United Downs

The two 2.5MW turbines, which were previously owned by RWE, are central to the plan to revitalise one of the UK’s pioneering wind farm locations. Burgar Hill was home to some of the world’s first multi- megawatt wind turbines and acted as a crucial testbed for onshore wind in the 1980s. It’s also home to one of Thrive’s oldest wind turbines – Sigurd &#8211; which has been operational since the early 2000s.  
Subject to obtaining necessary planning consents, <a href="http://www.burgarhillenergy.co.uk/" target="_blank" rel="noopener">the repowering project</a> is expected to have an installed generation capacity of up to 30MW which would deliver an estimated £150,000 in annual community benefits each year, aiming to create a lasting positive impact for surrounding communities.

In 2023 Thrive replaced the blades on our Sigurd turbine on Burgar Hill, which had reached the end of their life, working with ReBlade to repurpose them into useful items like bike shelters and EV charging stations &#8211; becoming one of the first UK companies to decommission wind turbine blades using circular economy principles.
