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