Construction begins at Twyn Hywel Energy Park in Caerphilly

< 3 minute read

Construction at Twyn Hywel Energy Park in Caerphilly, South Wales, is starting this summer after we secured £160 million in funding from Lloyds and Rabobank.

Reaching this stage – known as financial close – is a standard step for large infrastructure projects. It means the funding needed to build the project has been agreed with lenders, following detailed technical, environmental and financial checks. With this now in place, construction can begin.

This marks the move from planning into construction, with work now underway on site.

Sid Anverali, Project Director at Bute Energy said:

“This is our first energy park to move into construction, and that milestone reflects years of rigorous development work and the confidence our financing partners have placed in us. Twyn Hywel Energy Park will demonstrate the value homegrown renewable energy infrastructure can deliver for Wales, and it sets the foundation for the pipeline of projects we are bringing forward across Wales.”

 

Key facts about Twyn Hywel Energy Park:

  • £160 million funding secured
  • Construction starting summer 2026
  • Located in Caerphilly, South Wales
  • Civil engineering led by Knights Brown
  • Expected to support more than 300 jobs
  • Suppliers will offer apprenticeship and work experience positions
  • Annual £704,000 grant funding for the surrounding communities

What’s happening on site?

We’ve started work with Bridgend-based contractor Knights Brown, who are leading the civil engineering.

It will take over a year to build the park, and we’re working with experienced suppliers to ensure that safety comes first every step of the way.

There is a strong focus on local businesses, with around 90p in every £1 of Knights Brown’s contract expected to be spent locally. This includes using Welsh suppliers and creating local jobs during construction.

Alongside this, we expect to deliver around £365,000 in social value, supporting employment, training and investment in the area.

“We are now moving from plan to delivery, bringing jobs, investment and opportunity into the communities closest to the project. The project will support up to 300 jobs during construction, with an annual community benefit fund of £704,000 once the energy park is completed.

“Our approach to delivering sustainable investment means that communities will feel the benefit from our investment in clean energy infrastructure – from jobs and skills, community energy, The community benefit fund and a share in the ownership of the project.”

 – Martin Chown, CEO Bute Energy

Will the community have shared ownership of Twyn Hywel Energy Park?

We’ve developed a solid local ownership model:

  • 25% of energy operating energy park’s Community Benefit Fund will be allocated to support to local, small-scale energy projects such as hydro, wind and solar.

Great progress has already been made so far in the Caerphilly – Rhondda Cynon Taf area to explore what’s possible in the area.

In the meantime, we’re developing an additional model to give communities the opportunity to collectively own up to 15% of Twyn Hywel Energy Park. We’ll work with a Welsh organisation to help communities understand and manage their share.

Visit our community energy page to learn more about how we’ll support local communities build and progress small-scale renewable energy projects.

What are next steps for Twyn Hywel Energy Park?

Twyn Hywel Energy Park is our flagship renewable energy park, with another potential 12 parks planned for Wales.  Each at various stages of the planning process.

While construction continues on site – we’re also exploring further long-term investment options for Twyn Hywel Energy Park so that we can continue the development of our other energy parks in Wales.

We’re also recruiting volunteers to join a brand new community panel to help determine how the Community Benefit Fund will be invested locally.

What does “financial close” mean?

Financial close is a normal step in building large infrastructure projects. It means funding has been formally agreed with lenders, following detailed checks, so construction can begin.

Who was involved in securing funding for the project?

Reaching financial close involves a number of organisations working together to check and support the project.

  • Lloyds and Rabobank are providing the funding
  • We worked with specialist advisers on legal, financial and technical matters
  • Our contractors (including Knights Brown, H&MV and Nordex) supported the process by providing detailed plans, costs and delivery information

This is a standard approach for large infrastructure projects and helps ensure they are carefully reviewed before construction begins.

Who is building Twyn Hywel Energy Park??

We are working with experienced contractors:
• Knights Brown – civil engineering works
• H&MV Engineering – electrical infrastructure
• Nordex – wind turbine supplier

Are there opportunities for local jobs?

Yes. We are working with Big Issue Recruit to support people into jobs on the energy park. A dedicated job coach will work locally to help people overcome barriers to employment and access opportunities.

Can local communities invest in the energy park?

We are developing a local ownership model that will allow communities to collectively own up to 15% of the project, giving local people a direct stake in its success.

This is on top of our existing shared ownership model.  Click here to learn more.
