The geographic area on the borders of East Ayrshire, South Ayrshire, and Dumfries & Galloway is sparsely populated but rich in natural wind and hydro resources.
It has therefore attracted interest from developers wishing to connect significant renewable generation to the transmission system. As the existing network does not have sufficient capacity to cope with the level of demand, a new transmission network is required.
Known as the South West Scotland Connections Project, this work will support and facilitate the connection of wind farms in this area. Consent was granted for Part A Coylton substation to New Cumnock substation and associated overhead line in December 2012, work started in 2013 and construction works are now complete. Consents and associated permissions for Parts B-D were granted in 2014 and work commenced in 2016. The estimated construction programme for the completed project should take 3-4 years.
