Thrive’s Managing Director, Matthew, discusses this landmark project, the power of community energy and why onshore wind should be used to help end the UK’s dependence on dirty fossil fuels.

Positive News UK: The Bristol community building England's largest wind turbine

It’s less “drill, baby, drill” and more mill, baby, mill! In fact, it’s got us thinking about how getting to net zero is not only about delivering new projects but making the most of those that already exist.
<h3>What is repowering?</h3>
Repowering is when an existing project – like an onshore wind turbine – is upgraded to make it more efficient and productive. It normally takes place once the turbine or wind farm has reached the end of its original design life (usually after 25-30 years) and, because of innovations in technology, often sees multiple smaller turbines replaced with fewer, larger – but more modern and powerful – machines.
This normally increases the site capacity, for example when Caton Moor wind farm was repowered back in 2006, we were able to increase the annual power yield seven-fold. Importantly, it also means that asset owners can streamline the process that comes with developing a new project as the existing site has already been proven to be suitable for wind, will continue to be used for the same activity and has been granted planning permission previously.
<h3>What are the benefits of repowering? </h3>
1. Makes the most of our available onshore wind and land resources and reduces waste
One of the first things we saw the new Government introduce last summer was updated targets for renewable energy development in the UK, including a goal of 30GW of onshore wind by 2030. While it’s important to recognise that yes, we do need to add new capacity – including onshore wind – to the grid, we can’t forget that there are a finite number of sites that will be suitable for these technologies. It makes exercises like repowering a vital part of the journey as the land has already been allocated and in a prime location that makes the most of the country’s abundant natural resources.
It&#8217;s also worth noting that repowering can be done in a conscious way to reduce waste as parts can be recycled or reused – like with Caton Moor, the turbines which were removed from the site were re-erected in Poland within weeks of their removal.
2. Continued access to clean, homegrown power 
Onshore wind is currently one of the cleanest, cheapest and quickest ways to generate electricity and is vital to improving our energy security – making sure the country is less exposed to the price volatility that comes with using fossil fuels. However, in its 2024 manifesto, RenewableUK estimated that by 2040 we are in danger of losing almost 9GW of onshore wind (compared to the current total capacity of 15GW) as it reaches the end of its life. By repowering these sites, we won’t lose important generating capacity at a critical time for both the UK and planet, helping to accelerate the transition at the pace and scale required for net zero.
3. Community benefit 
We know that the majority of communities are supportive of onshore wind. In fact, according to the government’s latest polling, 7 in 10 (78%) are supportive of the technology and recognise its role in lowering bills, improving energy security and tackling climate change.
Repowering gives host communities the opportunity to continue benefitting from onshore wind, whether it be through the creation of local green jobs or support for local initiatives via community benefit funds. For example, Thrive’s voluntary Community Benefit Programme makes energy efficiency grants available to community buildings close to our sites. Since 2016, we’ve awarded 70 grants totalling over £225,000, helping to make important local spaces warmer and cheaper to run.
<h3>What are the barriers we need to overcome?</h3>
It was positive to see that the Government will include UK repowering projects in the next round of its annual Contracts for Difference scheme, creating the opportunity for onshore wind farms to utilise finance when funding repowering.  Access to the CfD should accelerate the repowering process, making the investment decision to seamlessly progress from the maturing site to the repowered opportunity more straight forward.
But we still need to see continued support and even a clear planning presumption or incentive in favour of repowering – not just for onshore wind but other renewable technologies too. This will then help engage local authorities around what we do with aging infrastructure and empower them to deal with applications appropriately as part of their wider transition plans.
The other challenge is grid connection. Even if a project can be successfully repowered, due to the current grid constraints asset owners may not be able to access additional grid capacity that would allow them to increase the generation capability of the wind farm. It means that they’ll be capped at the original generating capacity whilst waiting for the queues for grid capacity to subside, meaning the UK may not be able to realise the full benefits of repowering until these issues have been solved.
Grid reform recently featured in the Government’s Clean Power Action Plan, citing that NESO and Ofgem will provide a framework through which NESO can work with Transmission Owners (TOs) and Distribution Network Operators (DNOs) to prioritise the projects needed for 2030, as well as maintain a robust pipeline beyond 2030. As with other ongoing policy reform, we’ll be keeping an eye on how this unfolds and contribute to the appropriate public consultations what will hopefully help to accelerate our transition to a cleaner, fairer energy system in the UK.

It’s not all about the new “stuff”, we also need to consider how to make the most of our aging projects if we’re to meet net zero. 

Mill, baby, mill – Repowering to net zero

✅  Commitment to speeding up grid connections for renewable projects that are ready to go
✅  Promises to build on existing approaches to community benefits within the onshore wind sector as part of a fair and inclusive energy transition.
✅  Streamlining the planning process for critical infrastructure and new projects

The changes in the Action Plan are broadly welcome, however the urgency of the situation must not be underestimated. Only recently, the National Energy Systems Operator (NESO) described the UK’s 2030 clean power target as “ambitious but achievable” if renewables are expanding swiftly and significantly – doubling onshore wind and tripling solar.
Whilst the government’s clean power plan shows promising steps towards accelerating large-scale renewables, it is in danger of overlooking the importance of small to medium sized, local projects. These are the projects that put local communities at the heart of the energy transition. Smaller projects can fit better into the local landscape and generate electricity closer to where it is used, potentially reducing the number of pylons needed nationally.
We also need to make the most of the clean energy capacity that is already available to us by repowering existing projects i.e. replacing older wind turbines with fewer, more modern and efficient ones. For example, the 150m Ambition Community Energy wind turbine that was part funded by Thrive and built in 2023 can generate more than double the power of each single 125m wind turbine at our neighbouring Avonmouth wind farm built in 2014.
As we head into the new year let’s work together to keep the momentum up and push for urgent change at national, regional and local level to accelerate the rollout of the much-needed renewables revolution.

We share our thoughts on the government's Clean Power 2030 Action Plan. 

Let’s not forget smaller, local projects in the “new era of clean electricity”

As well as being our largest project to date, the deal marks another major step in our ambitious growth plans to double generation capacity within the next five years. It is the second project to be funded by Fair Play Clean Energy Ltd, Thrive’s Joint Venture with TopCashback Sustainability, which brings together a combined £80 million in capital to fund new clean energy projects in the UK.
Construction of the proposed 14-turbine site is expected to start in 2025, with commissioning planned by the end of 2026. Once operational, it will be capable of generating up to 149,400 MWh of clean electricity per year, the equivalent of powering 46,100 average UK homes<a href="#_ftn1" name="_ftnref1">[1]</a>, and delivering 65,300 tonnes of emissions reductions<a href="#_ftn2" name="_ftnref2">[2]</a>.
The Whitelaw Brae wind project was originally owned by developer, BayWa r.e., with Thrive acquiring the project in December 2024 following the successful completion of a competitive tender in October 2024.
Thrive has a record of delivering community and shared ownership, both at our own sites and by providing funding for community-owned energy projects. Now, we’ve acquired Whitelaw Brae, we aim to facilitate shared ownership at this site with Ripple Energy&#8217;s latest coop.

The wind farm site is located 15 km north of Moffat and 3 km south of Tweedsmuir. It is also near the River Tweed which, as part of the £25 million Destination Tweed initiative, will see the creation of a 113-mile source to sea River Tweed Trail connecting communities and attractions along the length of the river from Moffat to Berwick-upon-Tweed. The project aims to improve the landscape and river habitat and offer a unique experience to locals and visitors alike, expected to be completed across five years.
