Half year results 2025 – strong progress made on growth plan
In the first half of 2025, Thrive’s portfolio of wind, solar and hydro projects generated 63,082 MWh of clean electricity [1]. That’s enough to power more than 38,000 homes [2]. In total, the portfolio delivered emissions reductions equivalent to over 29,000 tonnes of carbon dioxide [3]. Read more in our half year report.
Half year operating profit was £3.9 million on a revenue of £9.4 million (41%), including the contribution from investments. This is compared to an operating profit of £7.4 million on a revenue of £14.6 million (50.6%) in the first half of 2024. The decrease in turnover and operating profit is the result of lower electricity prices, which are now returning towards pre-energy crisis levels.
Diversifying the portfolio
We continued to make strong headway on our growth plan to double generation capacity by 2028. Development of the two onshore wind farms we acquired in 2024 is well underway and earlier this year we acquired a 10MW ground mount solar farm in Essex. Dunmow solar farm is now operational, making the most of the sunshine we’ve experienced this summer. The site generated enough clean electricity to power over 8,000 homes in June, a very sunny month.
As well as acquiring new projects we’re committed to extending the life of our oldest assets. We’re pleased to be partnering with Burgar Hill Renewables to repower a wind project on Orkney, with plans to replace five of the current turbines (including our Sigurd turbine) with four larger and more efficient machines – harnessing the abundant natural resources at one of the best sites for wind generation in Europe.
Accelerating the energy transition through collaborative funding
We’ve always been big believers in community energy, investing over £21 million to date in community-led wind and solar. Now we’ve launched a £40 million funding partnership with Better Society Capital, the UK’s leading social impact investor, to offer flexible funding for community groups to build their own clean energy projects or take a stake in part of a larger project in their area. 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.
We’re also pledging to provide an opportunity for the community to own a share of every new project we acquire. Following through on that promise, we recently welcomed Community Energy Pathways and members of the local community to our Dunmow solar farm, who are helping us shape how shared ownership could work on this particular project.
Building a cleaner, fairer future for communities
For nine years we’ve been awarding energy efficiency grants to community centres near our clean energy projects – helping them become warmer, cosier and cheaper to run. The latest round of our Community Benefit Programme launched in August 2025 with grantees to be announced this Autumn.
In celebration of our 30th anniversary, this year we’re making an additional £30,000 available to help install solar panels on two community buildings close to our sites. This will be administered with the help of Centre for Sustainable Energy, which also runs our Community Benefit Programme.
Thrive’s mission is to create a cleaner, fairer future for generations to come. Earlier this year we were excited to get a small glimpse of what that future might look like. We welcomed the renowned food writer and environmental campaigner, Hugh Fearnley-Whittingstall, to our Avonmouth wind farm to film an advertisement with local children, exploring the extraordinary power of wind and sunshine. Watch the video below.

[1] Refers to Thrive’s impact portfolio – total electricity generation of the portfolio adjusted for Thrive’s proportion of ownership, plus the projects Thrive is funding
[2] Calculated using the most recent statistics from the Department for Energy Security and Net Zero (DESNZ) showing that UK average domestic household consumption is 3,301kWh per annum (1,650kWh for a half year)
[3] Carbon reduction is calculated by multiplying the total amount of renewable electricity generated by Thrive’s impact portfolio in the first half of 2025 by the number of tonnes of carbon which fossil fuels would have produced to generate the same amount of electricity. We have used DESNZ’s “all non-renewable fuels” emissions statistic of 437 tonnes of carbon dioxide per GWh of electricity supplied from the Digest of UK Energy Statistics (July 2024) Table 5.14 (“Estimated carbon dioxide emissions from electricity supplied”). Additionally, we include a conservative estimate of the carbon saved through operating our BESS projects.
