Hare Craig Wind Farm 33kV Connection

SP Energy Networks (SPEN) is required under its license obligations to provide a 33 kV overhead line (OHL) grid connection from the proposed Hare Craig Wind Farm to the proposed Redshaw Substation in South Lanarkshire.

SP Transmission plc (SPT) on behalf of SPEN, operates and maintains the transmission network as the transmission licence holder for the area. SPT is obligated under Section 9 of The Electricity Act 1989 to:

  • Develop and maintain an efficient, co-ordinated and economical system of electricity transmission.
  • Facilitate competition in the generation and supply of electricity.

SPT is obliged to provide a connection to the existing network for the wind farm. The Hare Craig Wind Farm grid connection is proposed to be developed in the Douglas Valley to the north-east of the settlement of Muirkirk, East Ayrshire and the grid connection extending to the east to the proposed Redshaw Substation between the M74 and the B7078 in South Lanarkshire.

Current Stage

The project is currently at the routeing stage and, as such, SPEN has prepared a Routeing and Consultation Document (RCD) for the connection which includes a strategic review of environmental, technical and economic considerations and the application of established routeing principles to identify the ‘preferred route’ for the proposed overhead lines.

We are now seeking feedback on the preferred route and the route selection process which has been undertaken to date.
