Mynydd y Betws is a mountain or large hill located on the northern side of the border between Swansea and Carmarthenshire[1][2] in South Wales, between Ammanford and Clydach.
The medieval castle of Penlle'r Castell is located on Mynydd y Gwair to the south-south west, Mynydd y Betws Wind Farm is prominent with fifteen 110 m (361 ft) wind turbines.
[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] Between July and September 2017 the turbines did not produce any electricity, with the whole farm being put into a "paused state".
