Coalburn Substation – South Lanarkshire

SP Energy Networks own and maintain the electricity network in central and southern Scotland. As part of our infrastructure, Coalburn Grid Substation is a key installation in the transmission network situated to the south of Lesmahagow in South Lanarkshire.

Wind farm developers have identified certain locations throughout Scotland as being rich in wind energy with South Lanarkshire being one of these areas. Due to Coalburn Substation’s geographic situation a number of wind farm developments in South Lanarkshire have requested connections to the transmission network and will be connected ultimately via the substation in the coming years. In addition, wider associated works to reinforce the existing network infrastructure will also feature in and around Coalburn Substation. These along with other connections through central and southern Scotland and beyond will support the nations move to clean energy and a sustainable environment for us all.

The information below sets out proposed and agreed connections at this stage that SP Energy Networks plan to undertake along with associated reinforcement activity.
