Wind energy

Wind Energy Programme

The Natural Resources Wales Wind Energy Programme aims to integrate wind farm development into the sustainable management of the Welsh Government Woodland Estate.

The Wind Energy Programme works with selected Developers (Option Holders) to deliver a significant contribution to the Welsh Government's onshore wind energy target.

Wind Energy Projects

The following section provides updates on the progress of each of the Wind Energy Projects as of October 2018.

Clocaenog Forest (27 turbines / up to 96MW)

Developer – Innogy Renewables UK Ltd

Construction at Clocaenog Forest wind energy project is progressing well. Ground preparation has been completed for the majority of the turbine bases with nine turbine bases now fully constructed.  The focus is now turning to excavation of the cabling routes.

Dyfnant Forest

Dyfnant Forest is within Welsh Government’s Strategic Search Area B and NRW is keeping the vacant Option under review.

Nant y Moch

Vattenfall has terminated its Option Agreement for SSA D - Nant y Moch due to the challenges in designing a viable project at the current time. Nant y Moch is within Welsh Government’s Strategic Search Area D and NRW is keeping the vacant Option under review. 

Brechfa Forest East

Brechfa Forest East is within Welsh Government’s Strategic Search Area G and has a Planning Authority consented onshore energy scheme.

NRW is considering the best way forward for realising this development.

Brechfa Forest West (up to 28 turbines / 57.4MW)

Developer – Innogy Renewables UK Ltd

The fully operational Brechfa Forest West Wind Farm is now officially open and has an installed capacity of 57.4MW, generating enough renewable energy to power 38,800 average Welsh homes annually.

Innogy started construction less than 2 years ago in November 2016, and the project has delivered significant opportunities and investment for local businesses. It is a £100 million development, with almost £40 million being invested in Wales during the 20 months of construction.

The opening officially launched the £459,200 annual Community Investment Fund and the first awards from the fund were made to:

  • Llanllawddog Community Hall - £5000 for defibrillators;
  • Ysgol Gyfun Bro Myrddin - £55,000 over 2 years towards a 3G Sports Pitch

The construction period is coming to an end, with the focus on finalising reinstatement works across the site. Innogy will deliver the Habitat Management Plan over the lifetime of the project and NRW are working closely with innogy to enter in to the Operating Lease for 25 years.

On other news Brechfa Forest West Wind Farm was recently awarded ‘Renewable Energy Project of the Year’ at the Business Green Awards. Further to that, NRW won a silver award in the Green Apple Awards for the Built Environment and Architectural Heritage, Beautiful Buildings category, for a footbridge over the Afon Pib, constructed by Innogy as part of the Wind Farm.

Pen y Cymoedd (76 turbines / 228MW)

Wales’s largest onshore wind farm is now fully operational. Natural Resources Wales is working closely with Vattenfall personnel on site to complete reinstatement and enter into the operating lease period for 25 years. Pen y Cymoedd expects to produce enough power annually to meet the electricity demand of more than 188,000 UK households, and will more than meet the domestic demand of host local authorities Rhondda Cynon Taf and Neath Port Talbot. Over the lifetime of the project it is expected to save 6.4 million tonnes of CO2.

Vattenfall is also constructing a battery storage scheme on site. The 22MW system – believed to be the largest co-located battery and wind farm project in the UK – will provide a rapid-reaction grid reliability service to National Grid, known as Enhanced Frequency Response.

To gain a better understanding of the site and to see some of the work that has already taken place, some aerial footage of Pen y Cymoedd is available to view.

Pen y Cymoedd Wind Farm Community Interest Company have now been set up to administer the Community Fund. More information can be found here:

Whilst public access is still allowed within the forest area, walkers and mountain bikers are encouraged to look out for banksmen, signage and noticeboards which convey information about onsite activity. Working areas can be found on the updated map.
