Proposed establishment of 132kV powerline to evacuate power from the Karreebosch WEF to the National Grid in the Western and Northern Cape

The development of a 132kV overhead power line to connect the Karreebosch Wind Energy Facility (WEF) Energy Facility to the national grid via the existing Eskom Komsberg substation. The powerline is approximately 20 km long. The project is situated north of the town of Matjiesfontein in the Karoo Hoogland Local Municipality and the Laingsburg Local Municipality in the Northern Cape Province and Western Cape Province. The 132kV grid connection crosses the following properties:
Wilgebosch Rivier 188 Remainder
Ekkraal (Nuwekraal) 199 Portion 2
Klipbanksfontein 198 Portion 1 and Remainder
Bon Espirange 73 Portion 1 and Remainder
Rietfontein 197
Ekkraal (Nuwekraal) 199 Portion 1 and Remainder
Standvastigheid 210 Portion 2 (Komsberg Substation)

The OHL will be a 132kV steel single or double structure with kingbird conductor (between 15 and 20m in height – above ground level). Standard overhead line construction methodology will be employed – drill holes (typically 2 – 3m in depth), plant poles, string conductor. It is not envisage that any large excavations and stabilized backfill will be required however this will only be verified on site once the Geotech has been undertaken at each pole position (part of construction works).
