Transnet Coallink Project - Duma

Construction of the proposed Duma transmission substation and associated power lines, as part of a suite of projects collectively known as the Ermelo - Richards Bay Coal Line Upgrade. The scope of works includes the construction of a 400/88 kV, 160MVA electrical Substation and associated 400kV and 88kV turn-in power lines connecting to the existing Athene Pegasus 400kV power line and Umfolozi Empangeni 88kV traction power line respectively, located 20km south-east of the town of Ulundi, KwaZulu-Natal. The “North” Alternative of the proposed development entails the construction of the afore-mentioned substation and 1000m of 88kV and 400kV turn-in power line corridors respectively to tie into the existing Umfolozi Empangeni 88kV traction power line and Athene Pegasus 400kV power line respectively. The “North” Alternative will also include the rebuilding part of the existing Umfolozi Empangeni 88kV traction power line, from the injection point of the proposed 88kV turn-in power line to the existing Kombe traction substation (approx. 12.5km in length). The proposed Transnet Coallink Project consisting of the construction of transmission substations, upgrading of existing transmission power lines and the construction of new transmission power lines traversing KwaZulu-Natal and Mpumalanga Provinces, from Empangeni to Ermelo south.
