Umsobomvu 400kV OHL Turn-in System

Umsobomvu Wind Power (Pty) Ltd. is proposing the construction of a 400kV turn-in system at the Koruson Substation (SS) (DFFE Reference: 14/12/16/3/3/2/730/2) in support of the proposed Umsobomvu WEF (DFFE Ref: 14/12/16/3/3/2/730) and Coleskop WEF (DFFE Ref: 14/12/16/3/3/2/730/1). The 400kV turn-in system will include two 400kV OHLs of up to 6km each in length. This is to ensure that electrical energy generated by the WEFs can be evacuated from the Eskom Koruson SS to the national electrical grid network via the existing Eskom 400kV distribution lines. Umsobomvu Wind Power is seeking the services from a South African-based EAP to carry out a full Scoping and EIA process, in the Northern Cape and Eastern Cape Provinces.

The proposed Umsobomvu 400kV Turn-in System will consist of the following:

  • Two (2) 400kV OHLs (assessed within 600m wide corridors) which will extend from the Koruson SS to the Eskom 400kV distribution lines in a northwest and southwest direction from the SS.
  • All other infrastructure, including roads, substation (Koruson), laydown areas, amongst others, have already received Environmental Authorisation (DFFE: 14/12/16/3/3/2/730/2)

CES has been appointed by Umsobomvu Wind Power as the Environmental Assessment Practitioner (EAP) to conduct the necessary EIA Process and secure the required Environmental Authorisation (EA) for the project in terms of the National Environmental Management Act (NEMA, Act No. 107 of 1998 and subsequent amendments) EIA Regulations (2014 and subsequent 2017 amendments).

Published: 05 August 2022

The Final Scoping Report was submitted to the DFFE for decision-making purposes on the 5th of August 2022.
