6.6 SOUTH GRID<br />
The South Grid consists of the area to the south-eastern side of Hydra substation, which predominantly falls within<br />
the Eastern Cape Province boundary. It comprises three Customer Load Networks (CLNs), namely: Port Elizabeth,<br />
East London, and Karoo. The current transmission network and CLNs are shown in Figure 6.11 below.<br />
Figure 6.11: Current South Grid network and CLNs<br />
The high forecasted average growth rate for Port Elizabeth CLN is mainly attributed to the new Industrial <strong>Development</strong><br />
Zone (IDZ) at Coega near Port Elizabeth. The expected peak demands by 2016 and <strong>2020</strong> as well as the average<br />
percentage load increase for the period, for each CLN are given in Table 6.11 below.<br />
