Kosmosdal Substation in Centurion was recently upgraded and its power capacity increased from 20 MVA to 40 MVA. The substation services Kosmosdal and its extensions, namely Blue Valley, Samrand, Louwlardia, Louwlardia Business Park and Candlewoods.
This R65 million project was triggered by a 20 MVA new bulk electricity application from the private developer, Growthpoint Property Group, for their proposed data centre development in the area. Working together, the City began the work to upgrade the substation in February last year until the completion of the project on 12 July 2022. The project scope of work included the following:
- Construction of the substation building to accommodate two stages of 11 kV switchgear panels and new 132 kV control and protection panels and related auxiliary equipment
- Replacement and installation of new single cables between the power transformers and 11 kV transformer incomer panels
- Replacement of all multicore control cables
- Replacement of all indoor electrical equipment, including the supply, installation and testing of twenty 11 kV switchgear panels, 132 kV control and protection panels, and batteries and battery chargers
