Geography

At 373 m (1,224 ft), Mynydd y Betws is the highest mountain in the City and County of Swansea, and the highest land between the River Loughor and the Upper Clydach River. A small road between Ammanford and Clydach passes very close to the summit, on which are located the historic ruins of Penlle'r Castell.[1] Little remains of this fort which was built to prevent armed marauders coming from the north and attacking Swansea. It was destroyed in 1252, not long after it was built.[2]

Wind farm

Mynydd y Betws is the site of a wind turbine farm. It was granted planning permission in 2009 and started producing electricity in 2013.[3] The original developers of the site were the renewable energy generating company Eco2, but in 2010, they sold the site to the Irish semi-state electricity utility ESB.[4] The mast of each turbine is 70 m (230 ft) tall and the blades are 40 m (131 ft) long.[5] With fifteen turbines, the wind farm has an installed capacity of 34.5 MW and is said to generate enough electricity to power 23,800 households, one third of the domestic usage in Carmarthenshire. The Mynydd y Betws Wind Farm community benefit fund provides grants for projects in neighbouring areas of Carmarthenshire, Swansea and Neath Port Talbot.[3]
