6.2.1 LADYSMITH and NEWCASTLE CLNs<br />
The Ladysmith and Newcastle CLNs are agricultural, with coal mining and associated industries in the Newcastle CLN.<br />
The Tugela third transformer project in the previous ten-year plan has been cancelled as load can be shifted to other<br />
stations during contingencies. The following projects are planned:<br />
Strengthening in these CLNs entails addressing N-1 transformer contingencies and they are as follows:<br />
• Looping into Bloukrans, the Venus – Tugela 275kV Line 2013<br />
• Normandie 2nd 250MVA - 400/132kV transformer 2013<br />
• Incandu 3rd 315MVA - 400/132kV transformer 2014<br />
• Normandie 3rd 160MVA - 400/88kV transformer 2016<br />
As part of the Generation plans, there is a project to integrate Ingula Power station in 2012 as follows:<br />
• Loop in Majuba - Venus 400kV Line<br />
• Construct new Ingula - Venus 400kV Line<br />
