Section 1: Nant Mithil Energy Park to Aberedw Hill

Further assessment showed that the power generated from the proposed Nant Mithil Energy Park can be transported on a single 132kV circuit as far as Aberedw Hill (approximately 11.3km), where a switching station at the foot of the hill can transfer it to a steel pylon double circuit. The single 132kV circuit between Nant Mithil Energy Park and Aberedw Hill can be supported on wood poles, meaning that steel pylons are not needed on this section of the route.

The switching station can also accommodate energy from the proposed Aberedw and Bryn Gilwern Energy Parks, which are at an earlier stage of development. These would also be able to connect to the switching station using single 132kV circuits, likely supported on wood poles.

Locating the switching station at the foot of Aberedw Hill allows all three proposed energy parks to connect at the same point, thereby reducing the need for additional infrastructure that would have been required if they were to connect to the network in different places.

The proposed route has been moved further away from Franksbridge than originally proposed, to increase the distance from the village.
