Pen y Cymoedd

The highest altitude wind farm in the UK

Pen y Cymoedd is our flagship onshore wind farm, located in South Wales. Its 76 turbines can produce enough electricity to power 15% of Welsh homes annually. In addition to the production of fossil free electricity, a 22MW battery is co-located at the wind farm.

The battery is able to respond to the needs of the grid system in less than a second  - supporting a stable supply of electricity to UK homes.

Electric vehicle charging stations are also installed at the wind farm, as we get ready to take our entire fleet of vehicles electric in the next four years.

The wind farm is located on an open access site, which attracts walkers and cyclists who ride its many trails and tracks. One of these is Blade – a mountain biking trail funded by Vattenfall.

Local benefits from the wind farm

Beyond the wind farm, more than 100 jobs have been supported by the project’s innovative community benefit scheme. Through a £1.8million annual investment, the funding is focussed on making a difference to the lives of local people – all made possible by the wind farm.

The environment at Pen y Cymoedd

The site is a working commercial forest, and through investment from the wind farm, will also develop a 1500ha habitat management scheme – focussed on restoring peatlands and native woodland across the site to enhance local biodiversity.
