[1] Innogy Renewables UK Ltd. proposed that the wind farm would be built in Strategic Search Area G, created as part of the Welsh Government's TAN 8[2] policy, published in 2005.

Brechfa Forest West Wind Farm, had a proposed capacity of greater than 50 MW; thus the application was submitted to the Infrastructure Planning Commission.

The Brechfa Forest West development, located near the Afon Pib valley, consists of 28 turbines with a maximum tip height of 145 metres.

They recommended approval, and DECC confirmed that development consent for Brechfa Forest West was granted on 12 March 2013.

[5] Construction on the Brechfa Forest West wind farm started in November 2016, and all turbines were operational in June 2018.
