Hellenic Cables-Douglas North Onshore Project


SP Transmission PLC (“SPT”) is one of UK’s largest grid operators. The existing Coalburn to Middlemuir 132kV underground cable circuit was required to be modified in order to facilitate the connection of 2 new wind farms; Douglas West (51 MW) and Kennoxhead Extension (60 MW). The works included modifications of the existing circuit as well as uprating of the existing cables and redesigning of the earthing system of both the new Coalburn to Douglas North and Douglas North to Middlemuir circuits to ensure that the bonding is balanced following the diversion required to connect Douglas North 132/33kV substation.

Hellenic Cables commissioned to deliver the supply and installation of 132 kV land cables required for the connection of Douglas West Windfarm to the new SPT 132 kV Douglas North collector substation and Kennoxhead Extension Windfarm to Middlemuir Windfarm substation, via modification of the existing Coalburn – Middlemuir 132kV underground circuit.
