Coylton Substation

Coylton Substation is situated in East Ayrshire - playing an important part in the transmission network allowing energy from local generation sources throughout Ayrshire and Dumfries and Galloway to be transported across central and southern Scotland and beyond.


A major project at the substation commenced in March 2022 involving the replacement of two 275 kV transformers. This work is required to allow increased capacity on the network.
