Mynydd Clogau

Mynydd Clogau Wind Farm is situated on working farmland near the village of Adfa which is around 10 miles north of the market town of Newton and 14 miles east of Welshpool.

The wind farm is set amongst delightful mid-Wales countryside which is popular with ramblers and mountain bikers.

The wind farm was originally built by RES/Novera Energy and opened in January 2006 after 10 months of construction. It was sold to Infinis in 2009 and became part of Ventient Energy in 2018. Its 17 turbines have an installed rating of 850kW, giving the site a capacity of 14.45MW with the ability to generate enough energy to power 7,242 homes*.

Benefiting local communities

There are two community trusts associated with Mynydd Clogau’s community funds: Tregynon Wind Farm Trust and Dwyriw Community Trust. These trusts have supported a number of different projects in nearby communities including providing direct support to local students to help with their study costs and supporting The Gregynog Festival (which is the oldest music festival in Wales). Other projects have included replacing seats at Tregynon Community Centre and supplying Smart TVs and installing a mobility lift at the Ysgol Rhiw-Bechan bi-lingual school in Tregynon.
