46 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 Transmission Ten-Year Plan 2011-2020
A diagram showing the major projects in the West Grid is shown in Figure 6.14 below. Figure 6.14: West Grid geographical network diagram 6.8 STRATEGIC SERVITUDES UNDER INVESTIGATION All the line projects and new substation projects that are proposed in the document need to go through a full environmental impact assessment (EIA) process before implementation. This process includes public participation meetings, which are advertised in the media. Concerns of the public and affected parties are addressed at the public participation meetings. Eskom Holdings will not commence construction of any line or substation without the EIA process (Record of Decision being signed and servitudes acquired) being concluded. The proposed lines shown in various schematics in this document give an estimation of where various proposed lines will run. The outcome of the EIA process will determine the exact position of the lines. The projects in this document are at various stages of the EIA process. © Eskom 2011 47
