Built on the Inverbroom Estate, we were approached to bridge a funding gap, complementing the £6.7 million of long-term loans being provided by Virgin Money (Clydesdale Bank).
Connected to the grid in October 2020, Loch a Bhraoin has the potential to generate enough renewable electricity for around 2,250 average UK homes, saving more than 3,800 tonnes of CO₂ emissions annually. With the loan now repaid, it’s a great example of investors, developers and landowners working together to get new renewable energy projects built!

We provided a mezzanine loan of £1.8 million to Inverbroom Hydro for the construction of a 2MW hydro-electric project in the Scottish Highlands.

Boosting Scotland's hydro capacity

Inverbroom case study

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.

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.

Here are some of the commitments we’re most pleased to see:
<h4>“Bottom-up” approach to the energy transition</h4>
Thrive was established 30 years ago to nurture and develop a bottom-up, peopled-powered approach to the energy transition, bringing together individuals, organisations and communities to get new clean energy projects built. So needless to say, we’re really pleased to see the vision of a people-powered energy system outlined in the Local Power Plan. More than just wires and turbines, community energy is power that is owned and controlled by communities themselves, where the benefits stay local. It’s energy by the people, for the people. We know this approach works – projects like the Ambition Community Energy (ACE) wind turbine, which is name-checked in the plan, are evidence of that. The ACE turbine in Bristol which Thrive helped fund is doing more than just deliver megawatts – as proud owners of England’s largest onshore wind turbine, it’s giving local residents in Lawrence Weston an active role in transforming the UK’s energy system, whilst providing a new local revenue stream.

Imagine what the impact could be if we could have the equivalent of an ACE turbine in every neighbourhood across the UK? That‘s the government’s ambition by 2030 – let’s hope it delivers.
<h4>Support for shared ownership</h4>
It’s encouraging to see a commitment to boosting shared ownership – enabling communities to take a stake in clean energy projects in their area. Shared ownership gives communities access to projects that are expertly developed and ready to go, including larger projects with more secure revenue streams.  Depending on the size of their stake, communities may have the opportunity to influence how a project operates. Since offering shared ownership in our first ever wind farm in the 90s, we’ve been committed to helping communities take ownership of energy on their doorstep. Now we’ve offering the community a share of every new project we acquire &#8211; currently exploring shared ownership opportunities at Dunmow solar farm in Essex which became operational last year and Abergorki wind farm which is being developed in South Wales.
<h4>Unlocking funding and capacity through collaboration</h4>
Community energy schemes generate 12 times the local economic value of commercial projects, yet currently generate only 0.5% the UK’s electricity. The sector is grappling with a lack of access to flexible funding, and a capacity and skills gap. The Local Power Plan promises to address the capacity gap, through developing new service models with tools and advice for communities to access, plus creating a strong partnership network across local, national and commercial bodies. It also intends to “crowd in” private investment. How this will be achieved is still not fully clear, but it is positive to see the government recognise the importance of a collaborative approach to rolling out community energy projects.
Our joint venture with Better Society Capital, Community Energy Catalyst (CEC), provides a working model of how collaborative finance can help more communities own projects in their area. The initiative provides flexible funding to complement government grants and other sources of finance, plus industry specific skills and expertise. CEC will help support the ambitions of the Local Power Plan by providing the flexible funding community energy groups need to bring projects to fruition.
<h4>Now is the time to Up the Energy</h4>
The commitments made in the Local Power Plan have the potential to transform the community energy sector. But at the moment, they are still just commitments. What we need to see now is regulatory changes in practice to remove the barriers that are preventing the sector from accelerating at pace. We’re particularly concerned to see more detail on how government intends to support communities in establishing clearer routes to sell locally generated power – as this is crucial for attracting investment from the private sector and ensuring the benefits of local energy are maximised for the host communities.
With the backing of organisations across the UK, including Thrive, Community Energy England are asking government to turn words into action by removing barriers to community energy and strengthening support.
