The access to build this wind farm will be via the roads built by RES over Mynydd Maen, extended across further peat bog to Rhyswg farm land, on the hilltop between Cwmcarn/Cwmcarn Forest Drive and Abercarn/Llanfach.
The construction and operation of up to 3 wind turbines up to 180m in height to blade tip together with associated infrastructure.
Pre-Application consultation 25th November 2025 – 30th January 2026.
Pennant-Walters has registered with PEDW an interest in building yet another wind farm on the mountain between Cwmbran, Abercarn and Newbridge, in addition to their Trecelyn proposals.
Please attend one of these meetings to let Pennant Walters know that Mynydd Maen is not the right place for an industrial sized energy park:
1. Monday 8th December 2025, 2:00-7:00 pm, Llanfach Village Hall, Abercarn
2. Tuesday 9th December 2025, 2:00-7:00 pm, Newbridge Memo
If plans go ahead, Rhyswg and Trecelyn wind farms, with Cil-lonydd solar farm, will connect to the Mynydd Maen wind farm. This will form a giant industrial energy park on top of the mountain, complete with dual carriageway roads, battery parks, substation buildings, a criss-cross of cable routes, solar panels and turbines. Aviation lights will be installed on the Rhyswg turbines, as they will be 180m (590 feet) in height (over the 150m limit). This is the equivalent of a 60 storey building.
The community of Llanfach in Abercarn will be dominated by giant turbines to the north and east, at heights similar to Canary Wharf in London, when the height of their bases is included. Disruption to traffic through Pantside will be horrendous, and also through Llanfach, past the childrens’ playground. Developers have told us they can’t prevent hundreds of construction workers taking any route they choose to reach the site.
