SP Energy Networks (SPEN) has been contracted by National Electricity System Operator (NESO) to connect the proposed Carrick Wind Farm to the National Grid.
SPEN have a licence obligation to provide electricity generators with a connection to the electrical system in this area. To enable this, we are proposing to deviate the existing 275kV Coylton to Auchencrosh circuit (known as YY route) into the proposed Carrick 275/33kV substation to connect the wind farm to the transmission network. The proposal includes the removal of three existing towers from YY route, to be replaced with four new towers and associated OHL conductors to maintain a continuous connection in and out of the substation.
The Proposed Development is located within the administrative boundary of South Ayrshire Council and covers a length of approximately 1.3 km of the existing YY route, c.8km south of Straiton, South Ayrshire. The section of YY route subject of the proposed development is located within the southeast portion of the Carrick Wind Farm development boundary.
A tower siting study has been carried out to assess the most appropriate locations for the new towers from an environmental, technical, and economic perspective.
The consultation period ran from October 7th until Friday 8th November 2024. Details of the consultation and responses received can be found in our Consultation Feedback Report:
An EIA Screening Request for the proposed development was submitted to the Energy Consents Unit in February 2025, and confirmation that the project did not constitute EIA development was confirmed in July 2025. Details of the case can be found on the Energy Consents Unit website under reference ECU00006092.
Further environmental and technical surveys are now taking place to inform the detailed design of the development, and following this application is to be submitted to Scottish Ministers for consent under Section 37 of the Electricity Act 1989 and for deemed planning permission under Section 57(2) of the Town and Country Planning (Scotland) Act 1997 to carry out the works.

The proposed Carrick Substation was the subject of a separate EIA screening request and subsequent Town and Country Planning (Scotland) Act 1997 application to South Ayrshire Council, who also confirmed the substation does not constitute EIA development. Details can be found on the South Ayrshire Council planning portal, under reference 25/00313/EIASCR.
The public will be notified and consulted on this development separately through the formal Pre-Application Consultation process associated with the Planning Application.
