Proudly based in Wales, Green GEN Cymru has been granted an Independent Distribution Network Operator (IDNO) Licence from Ofgem. We are developing new grid infrastructure to unlock Wales’ energy capability and meet the future needs of its’ people, communities, and businesses.
The Rhiwlas project is a proposed wood pole overhead line (132kV) connecting the proposed Rhiwlas and Banc Du Energy Parks near Llangurig to a new collector substation near Cefn Coch. As well as a new underground cable connection between the two proposed Energy Parks.
The project will contribute to Wales’ energy resilience and ambitions, enable local businesses and communities to grow and decarbonise, and help accelerate the rollout of low carbon technologies, including heating and electric vehicles.
We held two non-statutory public consultations in winter 2023 and 2024 on the proposed route and pole locations.
We will be running a targeted consultation on the route section between Clatter and Cefn Coch from Wednesday 11 February 2026 to Wednesday 11 March 2026.
