Nant Mithil Energy Park set to deliver long-term benefits for Powys.
We’ve responded to Powys County Council’s draft Local Impact Report for our proposed Nant Mithil Energy Park in Radnor Forest, around 9km east of Llandrindod Wells.
The Local Impact Report, submitted by Powys County Council, recognises the long-term economic, environmental and social benefits our energy park could deliver for communities across Powys and mid Wales – from clean, reliable energy and skilled jobs to biodiversity improvements and direct community investment.
What is Nant Mithil Energy Park?
Nant Mithil Energy Park is a proposed onshore wind energy project in Radnor Forest, Powys. Our energy park would generate enough clean electricity to power up to 193,000 homes, while supporting local jobs, strengthening Welsh supply chains and delivering lasting benefits for nearby communities.
How Nant Mithil Energy Park supports Wales’ clean energy goals
The Local Impact Report highlights the important role Nant Mithil Energy Park can play in supporting a more resilient, low‑carbon energy system for Wales.
It also recognises opportunities to improve access, recreation and enjoyment around the site, while delivering a net gain for biodiversity, including benefits for the Radnor Forest Site of Special Scientific Interest (SSSI).
Construction impacts assessed as neutral
The report found construction impacts to be neutral across several areas, including:
- Transport of turbine blades, tower sections and other abnormal loads
- The River Wye
- Common land
- Ground conditions
- Protected species, including bats, badgers, otters, newts and fish
We’ll continue working closely with Powys County Council and other consultees to avoid or minimise impacts through minor design changes, clarifications and agreed mitigation measures.
What economic and community benefits will Nant Mithil Energy Park deliver?
To support the planning application, we’ve submitted an Economic Benefits Statement and a Collaborative Benefits Report (both can be viewed by clicking this link). These set out how the Energy Park could deliver real value for communities, businesses and public services across Wales.
Key benefits include:
- Generating enough electricity to power up to 193,000 homes
- Displacing up to 287,000 tonnes of CO₂ each year
- Supporting up to 1,200 direct, indirect and induced person‑years of employment in Wales over the project’s lifetime
- Delivering a £176.5 million gross value added (GVA) impact for Wales
- Contributing up to £2 million per year to essential public services through business rates collected by Powys County Council
- Driving investment in Welsh supply chains, including site security, plant hire, and wind farm operation and maintenance
Creating jobs and skills in mid Wales
We’re focused on creating local jobs and long‑term skills opportunities in mid Wales. We’re already working with organisations including Young Farmers, Lantra Wales and Coleg Sir Gar to deliver training, qualifications and greater awareness of careers in the renewable energy sector.
What matters to people in Powys.
If the energy park were to go ahead, we’ll invest £1.5m every year into the local communities through a Community Benefit Fund.
Through engagement with local organisations over recent years, communities have identified key priorities for investment, including:
Cost of living – working with partners to improve energy efficiency and tackle rising costs
Education – supporting renewable energy education in local schools and colleges
Social mobility – creating work opportunities and engaging with young people
Environment and culture – supporting local heritage, culture and environmental projects
Recreation and health – improving access to recreational and wellbeing activities
Enhancing the local environment
Alongside clean energy generation, Nant Mithil Energy Park would deliver a range of environmental enhancements, including:
- Habitat restoration
- New hedgerows and pond creation
- Removal of invasive species
- Creation of 10.5 hectares of new broadleaved woodland through tree planting
These measures would help strengthen local ecosystems and deliver long‑term environmental value.

“We want this investment to deliver real, lasting benefits for local communities, businesses and the environment. Our plans will create skilled jobs, support Welsh supply chains and bring long‑term value to the Welsh economy. We look forward to continuing to work with local partners to make the most of this opportunity.”
Dafydd Williams, Senior Project Manager
What happens next?
Following Powys County Council’s committee meeting, the Local Impact Report is expected to be finalised and submitted to Planning and Environment Decisions Wales (PEDW) by 16 February 2026.
The application is being considered as a Development of National Significance and will ultimately be decided by Welsh Ministers.
Frequently asked questions about Nant Mithil Energy Park
Where is Nant Mithil Energy Park located?
The Energy Park is proposed for Radnor Forest in Powys, around 9km east of Llandrindod Wells in mid Wales.
How much energy will Nant Mithil Energy Park generate?
It could generate enough clean electricity to power up to 193,000 homes each year.
How will local communities benefit?
Communities would benefit through jobs, supply chain opportunities, a £1.5 million annual Community Benefit Fund, and investment in education, environment, recreation and cost‑of‑living support.
Will the project affect wildlife and habitats?
Environmental assessments show the project would deliver a net gain for biodiversity, with habitat restoration, woodland creation and protections for local wildlife.
At what stage of planning is Nant Mithil Energy Park?
Since launching the project to the public in autumn 2022, we have undertaken a thorough engagement process, starting with an initial (non-statutory) round of consultation with the public, followed by a second (statutory) consultation with the public in late spring and early summer 2024.
We’ve undertaken more detailed studies since then, and our designs have evolved following feedback from key stakeholders, the community, and landowners. We’d like to thank everyone for taking part.
We submitted the Development of National Significance (DNS) application to PEDW in December 2024. We have reached an important milestone in the planning process – on Tuesday 18 November 2025, PEDW accepted the application and progressed it to the consultation stage.
Who will make the final decision?
The project is being considered as a Development of National Significance and will be decided by Welsh Ministers following examination by PEDW.
