Environmental Impact Assessment For The New Weskusfleur Substation


Eskom Holdings SOC Limited needs possible alternatives and solutions to address the long term reliability and improvement of the existing 400kV Gas Insulated System substation (GIS) at Koeberg Nuclear Power Station in the Western Grid. It is for the aforementioned reason that a new 400/132kV substation (Weskusfleur Substation) will be required in the vicinity of the Koeberg Power Station to:
•Improve the existing 400kV reliability
•Cater for load growth on the 132 kV network for the 20-year horizon.
•Prevent overloading of existing 400kV busbar
The construction of the substation needs authorisation from DEA and Lidwala was the appointed specialist for the application and environmental authorisation.


A scoping face has commenced and the first draft scoping report is out for public review and comments. Specialist’s studies were done to assess the entire alternatives site. The technological alternatives were also assessed between Air insulated Substation (AIS) and the gas insulated Substation (GIS).
After the review period the comments will be addressed and incorporated into the final scoping report and submitted to the Department of Environmental Affairs (DEA) for approval of EIR phase.
