Bon Espirange substation and 132kv overhead power line for the authorised Roggeveld wind farm project

Roggeveld Wind Power (Pty) Ltd received environmental authorisation for Phase 1 of the Roggeveld Wind Farm on 12 August 2014. In order to connect the Roggeveld Wind Farm to the high voltage electricity network (grid), an on-site substation (known as the Bon Espirange Substation Eskom Yard) and a new overhead power line is required to be constructed. The Bon Espirange Substation Eskom Yard applied for in this Basic Assessment process will be located directly adjacent to the authorised Bon Espirange Substation IPP Yard (overlapping with the area assessed through the Roggeveld Wind farm EIA). The entire extent of the Bon Espirange Substation, including both the Independent Power Producer (IPP) Yard and the proposed Eskom Yard, is located within the authorised Roggeveld Wind Farm Facility site. The 132kV overhead power line (6-7 km in length) will connect the Bon Espirange Substation to the Eskom Komsberg Substation. The authorised connection for the Roggeveld Wind Farm is no longer viable due to a proposed expansion of the Komsberg Substation. Therefore, the point of connection to the Komsberg Substation has been reconsidered, and the only viable connection solution for the Roggeveld Wind Farm is to connect to the Komsberg Substation on the eastern side of the substation. Limited upgrades might also be required to the Komsberg Substation including but not limited to additional feeder bay, limited access roads and cabling. Any upgrades to the Komsberg Substation would be determined by Eskom at a later stage, but would be within the Komsberg Substation high voltage yard boundary
