Sclenteuch Wind Farm Connection

Scotland is a world leader in the fight against climate change. We are producing more clean, green energy than ever before, and we need to strengthen the transmission network so we can get it to the homes, businesses, hospitals and public services that need it.

SPEN is required in terms of its statutory and licence obligations to provide for new electricity generators wishing to connect to the transmission system in its licence area. SPEN is also obliged to make its transmission system available for these purposes and to ensure that the system is fit for purpose through appropriate reinforcements to accommodate the contracted capacity.

An application was received via the National Electricity System Operator from the Sclenteuch Wind Farm developer requesting a connection from the wind farm substation to the grid. As such, we are proposing to build an overhead line (OHL), to connect the wind farm to the electricity transmission system via Coylton substation.

The Proposal

The Sclenteuch Wind Farm Connection involves the construction of a new 132kV overhead line between the Sclenteuch Wind Farm substation located about 5km west of Dalmellington, within East Ayrshire and the existing Coylton substation, 2km west of Drongan. The new overhead line connection will be around 16km long and supported on trident wood ‘H’ poles.

If you would like a hard copy version of any consultation materials, please contact us. Any materials can also be made available in large print format.

Have your say

We consulted the public and wider stakeholders on our proposals between Wednesday 16th April and Friday 16th May 2025, holding in-person consultation events at the following locations:

Tuesday 22nd April: Miners Suite, Dalmellington Community Centre from 2.30PM to 7PM
Wednesday 23rd April: The Young Farmers Room, Stair Community Centre, 11:30AM - 5PM

We will review all feedback received and publish a Consultation Feedback Report in the coming weeks.

Should you require any further information about the project please contact sclenteuchconnection@spenergynetworks.co.uk

What happens next

Following the first round of consultation we will develop a detailed design and alignment for the new project overhead line, including locations for wood poles, access routes and working areas. We will publish a report summarising the feedback received in this first round of consultation and how this has influenced our proposals.

We will carry out environmental surveys and reports, and hold a second round of public consultation, so that people can give us their views on detailed route alignments.

After considering the feedback received in the second round of consultation, we will finalise our project proposals and submit consent applications to the Scottish Government’s Energy Consents Unit, for consideration by Scottish Ministers. The Scottish Ministers will then undertake a final round of statutory consultation before making any decision on our applications.
