South West Scotland Renewables Connection Project
SP Transmission Ltd has made a series of applications under Section 37 of the Electricity Act 1989 and the Town and Country Planning (Scotland) Act 1997, for a number of new overhead transmission lines and underground cables, with associated substation works, required to connect seven proposed wind farms to the electricity network. The seven wind farms requiring connection are: Kyle; Dersalloch; Brockloch Rig; Pencloe; Afton; Whiteside Hill and Ulzieside.
The SWS Project
The Project comprises a number of individual connections from the wind farms and also new SPT infrastructure required to collect the energy generated and then transport it back to the national electricity network. The individual connections and associated new substations are outlined below:
Part A: Coylton Substation Extension and 14.3km of 400kiloVolt (kV) Overhead Line and Meikle Hill Substation
Part B: Black Hill Substation and 14.8km of 132kV Overhead Line to Meikle Hill Substation
Part C: Glenglass Substation and 12.9km of 132kV Overhead Line to Black Hill Substation
Part D: The Wind Farm Connections comprises:
- D1: 6km of 132kV overhead line from the proposed Kyle (North) wind farm to the new substation at Meikle Hill;
- D2: 10.6km of 132kV overhead line from the proposed Dersalloch wind farm to the new substation at Meikle Hill;
- D3: a 132kV substation (Dun Hill substation) and two 100m underground 132kV cables connecting the Dun Hill substation directly into the overhead line between the Black Hill and Meikle Hill substations;
- D4: a 1.4km 33kV underground cabled connection from Pencloe wind farm to the new substation at Black Hill.
Key Stages of the SWS Project
Stage 1 Routeing
Following a strategic review of technical, economic and environmental constraints, a 'preferred' route for each connection was identified. SPT undertook consultation on Part A in April 2007.
As part of the strategic routeing for Parts B, C and D, known as the Ayrshire Wind Farms Grid Connection Project, SPT undertook consultations with statutory consultees and stakeholder groups.
Stage 2 Environmental Impact Assessment (EIA) Scoping
An EIA Scoping Report for the SWS Project was submitted to the Scottish Government on 21st September 2007, with an accompanying request for a formal Scoping Opinion.
Stage 3 Preparation of Environmental Statement
An Environmental Impact Assessment (EIA) of each of the individual grid connections was undertaken by Land Use Consultants (LUC) and associated specialists, culminating in the preparation of an Environmental Statement (ES) which presents the findings of these EIAs. The ES for the SWS Project was submitted to the Scottish Government on 18 February 2009.
