Be part of the clean energy movement

At Thrive, we recognise the important role battery storage has to play and are busy building our second project &#8211; a 20 MW site &#8211; in Bristol.
Read more about the background to the project (it involves a campaign to stop 48 diesel generators being built near a local nursery school!) and what it means for net zero in <a href="https://www.positive.news/society/a-key-piece-of-the-puzzle-for-a-more-energy-secure-uk-storage-and-more-of-it/" target="_blank" rel="noopener">our article with Positive News.</a>

Thrive’s Managing Director, Matthew, and Investment Manager, Tom, sat down with Positive News to talk about our battery projects and why they are so critical to the energy system of the future.

A key piece of the puzzle for a more energy-secure UK? More storage!

You may have noticed it felt a little less breezy than usual at the start of the year. But when wind speeds were below average, solar pulled through – balancing out low wind generation with plentiful power from the sun. In fact, the 2 billion kilowatt hours plus of solar generation delivered at the start of 2025, almost balanced out the reduction in wind power. Wind speeds quickly returned to the long-term average, pushing gas generation back down to record lows. By June, gas fell to just 21% of Britain’s power mix.   
What this shows us is that the British weather is ideal for clean power generation. Wind and solar complement each other &#8211; when one drops the other often steps up. The Ember analysis shows that there are only 2% of days in a typical year in Great Britain when both wind and solar generation are low. In other words, on days that it is not sunny, it is almost always windy – or a combination of both.   
This data confirms that in order to build a secure and reliable clean power system, we need a diverse mix of both wind and solar. It’s why Thrive is focused on diversifying our portfolio, most recently acquiring a 10MW solar farm to complement our fleet of wind projects. Dunmow solar farm certainly made the most of this year’s sunshine, generating enough clean electricity to power over 8,000 homes in June, which was particularly sunny. Meanwhile we have two new onshore wind farms in construction to further complement the portfolio, which also includes hydro, solar and battery storage. 
Whilst solar and wind can be considered the backbone of renewables generation &#8211; and are well aligned to support peak electricity demand during the daytime – hydro, tidal and geothermal can provide consistent baseload power when the sun sets and the wind dies down. Technologies benefiting from a mix of natural resources, plus storage systems, can be used to smooth out the delivery power on the occassions when wind and solar are less abundant. In other words, creating a clean power system that works for us all is very much a team effort, with each of our infinite energy resources playing their part.

Britain’s renewables dream team

Soon to become operational, the turbine will be Scotland’s first subsidy free, 100% community owned wind turbine, capable of generating over 7,000 MWh of clean electricity a year – enough to power more than 2,000 average UK homes. Profits from electricity sales will be reinvested back into the local area, helping to drive regeneration. Plans are already in motion to refurbish a central community hub, the Knox Institute, which aims to provide educational and recreational facilities for local people.
Kilbirnie is the first of many projects intended to be funded via the Community Energy Catalyst (CEC). The joint venture was formed to enable us to help more communities to build their own clean energy infrastructure or secure stakes in larger regional renewable energy schemes. Fair Play Clean Energy, Thrive’s existing joint venture with TopCashback Sustainability Ltd, will provide £20 million of the investment, with Better Society Capital providing matched funding.

Kilbirnie community owned wind turbine is the first project to be funded by our new joint venture with the UK’s leading social impact investor, Better Society Capital.

Community Energy Catalyst makes first investment

On the other side, an anti-ESG movement has emerged. We only have to look at what is playing out particularly in the US to see the impact right-leaning politics is having, with legislative steps being taken to curb what is being called “woke capitalism”. As a result, a worrying number of big corporates have started rolling back their commitments on everything from net zero to Equity, Diversity and Inclusion (EDI). Others are going in the other direction, engaging in “greenhushing” – a term for the growing number of companies staying quiet on their ESG progress due to backlash fears.
In positive news, <a href="https://www.businessgreen.com/news/4517536/research-majority-uk-investors-progressing-esg-policies-despite-us-backlash" target="_blank" rel="noopener">new research from Isio</a> has found that 97% of UK asset managers have an established ESG policy combined with dedicated sustainability teams in place. The survey also shows ESG integration remains at &#8220;robust&#8221; levels with 69 per cent of asset managers committing to the UK Stewardship Code in 2025, up 4 per cent on 2024. Similarly, it showed 65 per cent of respondents had established net zero plans in 2025, compared to 58 per cent in 2024.
These are no doubt muddy waters, but it doesn’t mean that there aren’t companies out there still genuinely committed to the core principles of ESG and positive impact. It just means that the divide is getting bigger between the companies that live and breathe these values, and those that have up until now used ESG as a smokescreen.
Integrity matters 
So, what do responsible businesses do faced with this changing world? We shouldn’t be shying away from the controversy but doubling down on our values. It’s about having a clear and simple vision that does not change with the political or social winds. Whether it’s called ESG or something else, the commitment to having a positive impact remains. And <a href="https://bcorporation.uk/news-stories-and-events/news/b-corps-outperforming-ordinary-businesses-new-data-shows/" target="_blank" rel="noopener">research from B Lab UK</a> has also shown that purposeful businesses are succeeding, with Certified B Corporations outperforming ordinary businesses in areas including revenue growth, talent acquisition and social and environmental impact.
As a UK B Corp scoring in the top 3% for impact, Thrive has been prioritising people and planet for over 30 years. It’s the basis of every decision we make – from the projects we invest into to the way we incentivise our staff. That resilience has allowed us to invest in 45 clean energy projects, 6 of which are 100% community owned, generating over 2.3 billion kWh of clean electricity and preventing the emission of over 1 million tonnes of CO2. To us, prioritising environment and society is simply good governance and one of the reasons why impact-driven businesses will continue leading long after the next buzz word has come and gone.

From a corporate trend to a political movement, it doesn’t matter if it’s called ESG or something else. A true impact-driven business will always put their money where their mouth is.

Has politics killed the ESG star? For us, integrity is what really matters
