What does the project involve?
Rhiwlas Green Energy Network (Rhiwlas GEN) is a new 132kV (132,000 volt) overhead line, approximately (35km in length) supported on wood poles that will run between Rhiwlas Energy Park near Llangurig and a new substation near Cefn Coch, Llanfair Caereinion. The proposed substation will be part of Green GEN Cymru’s Vyrnwy-Frankton connection project).
Rhiwlas GEN will also consist of a new 33kV underground cable route of approximately 3km long, to connect the proposed Banc Du and Rhiwlas Energy Parks.

Two public consultations for Rhiwlas GEN were held in 2023 and 2024. These sought views on the route corridor and the proposed wood pole locations along the whole route.
Following these consultations, we carefully reviewed each piece of feedback, including specific suggestions for design changes, and considered the findings of ongoing environmental and engineering surveys.
This process identified areas where updates could be made to our proposals, including moving the route alignment eastward outside the previous consultation corridor between the collector substation near Cefn Coch and Clatter.
As this represented a change, we launched a targeted consultation on this specific section to give the community an opportunity to provide feedback before the statutory consultation on the whole route later in 2026.
The targeted consultation on the route section between Clatter and Cefn Coch ran from Wednesday 11 February 2026 to Wednesday 11 March 2026 and is now closed.
