6.7.4 NAMAQUALAND CLN
The Namaqualand CLN is supplied via the Aggeneis MTS. All the stations in this CLN have single in-feeds. A number of
projects are included to bring it into compliance with the minimum security standard of N-1 redundancy. The Kronos
400/132kV transformer is needed to strengthen the local distribution network which is expected to become loaded
to capacity.
The projects within the Namaqualand CLN are as follows:
• Install Paulputs second 220/132kV 125MVA transformer 2014/2015
• Construct Aggeneis-Helios 400kV line 2017
• Construct Aggeneis-Nama-Gromis-Oranjemund second 220kV line 2017
• Construct Aggeneis-Paulputs second 220kV line 2017
• Kronos 400/132kV transformer 2017
Northern Cape Reinforcement Ferrum–Garona–Nieuwehoop 400kV
• Install Garona 1 x 125MVA 400/132kV transformer 2017
• Construct Ferrum–Garona first 400kV line 2017
• Construct Garona–Nieuwehoop first 400kV line 2017
6.7.5 SOUTHERN CAPE CLN
This CLN includes Beaufort West, Oudtshoorn, the Garden Route, and the Overberg. The main strengthening
foreseen in this CLN is to accommodate the conversion of OCGT generation at Gourikwa to CCGT, which will
require additional 400kV lines to evacuate the resulting increased output. The date of this project is uncertain, and it
has therefore been omitted. The projects within the Southern Cape CLN are as follows:
• Establish the Blanco 400/132kV substation 2016
• Construct the third Gourikwa-Proteus 400kV line 2019
• Construct the second Proteus-Droërivier 400kV line 2017
