Kudu Transmission Integration

The planning of the integration of Kudu Transmission Station into the NamPower Transmission Network and the Eskom Transmission Network is at an advantaged stage of planning and is foreseen to consist of two 400 kV feeders to the Eskom network and one 400 kV feeder to the NamPower network as well as other deep connection upgrades in the NamPower network depending on the PPAs.


West Coast Strengthening

The project consists of:

  • 1. A twin-circuit 220kV transmission line from Walmund near Swakopmund to Rossing that was recently commissioned;
  • 2. Another 220kV transmission line from Khan (near Ebony siding) to Lithops and Walmund to Kuiseb;
  • 3. Twin-circuit 132kV line to the new Husab Mine that was commissioned in December 2013. A substation called Lithops (near Arandis)
which will provide the main supply to Husab will be commissioned in November 2014.
