Blackcraig and Margree Wind Farm Connection

This Project which is now largely complete provides a link between the windfarms at Blackcraig and Margree and New Cumnock substation situated between New Cumnock and Dalmellington. New Cumnock substation provides a link to the wider transmission network.

This Project will be delivered alongside the Southwest Scotland Connection Project.

The grid connection comprises three separate elements:

Part A

Constructing a new 132kV wood pole overhead line between Blackcraig substation and Margree substation. Construction of Blackcraig substation and a 33kV underground cable between Blackcraig windfarm and Blackcraig substation – successfully completed and energised.

Part B

Construction of new 132kV wood pole overhead line between Margree substation and Dalshangan Sealing End Compound. Construction of Margree substation and Dalshangan Sealing End Compound.

132kV underground cable between the overhead line and Dalshangan Sealing End Compound – now complete.

Part C

Construction of a new 132kV steel lattice tower line between New Cumnock substation and Dalshangan Sealing End Compound – now complete.

The removal of the redundant N-Route overhead line (which the new line replaced) is now underway. Over 120 transmission towers are scheduled to be removed as part of this work.

Covid 19

SP Energy Networks have reviewed and assessed all activity including working practices at site - a range of additional measures have been introduced which will allow us to carry out the work as safely as possible.

Associated Works

As a consequence of the development of the Project, the felling of commercial forestry has taken place allowing the construction of the overhead lines, underground cables and substations and also to maintain the required clearances for safe construction and maintenance of the overhead lines.
