A single circuit 132 kilovolt (kV) overhead line (OHL) supported on wood poles, from the proposed Greenburn Wind Park Project substation to the existing New Cumnock substation in East Ayrshire.
SP Transmission (SPT), as holder of the transmission license for SP Energy Networks (SPEN) is proposing a new overhead line connecting the proposed Greenburn Wind Park Project substation to the grid network. This public consultation seeks your comments on the proposal.
The overhead lines would run at 132kv, would be supported on ‘Trident’ wood poles and would have a potential height range of 10m to 22m above ground, including insulators. Span lengths of the overhead line between poles would be in the range of 80m to 100m.
The construction of overhead lines requires additional temporary infrastructure such as temporary accesses to pole locations. All have limited maintenance requirements, and all are subject to well-established procedures for dismantling/ decommissioning.
Following establishment of the proposed routes, SPT intends to submit an application to the Scottish Ministers for consent under section 37 of the Electricity Act 1989 and deemed planning permission under section 57 of the Town and Country Planning (Scotland) Act 1997. Submission of the Section 37 application is anticipated in October 2025.
The first round of public consultation ran from Wednesday 22 January to Wednesday 19 February 2025.
You can find a summary of the feedback from that round in the Consultation Feedback Report located in the documents section below.
