Eskom Delphi Substation Expansion Basic Assessment Project

The Eskom SOC Limited wishes to expand the existing Eskom Delphi Substation to make provision to connect an additional 300 MW to the 100 MW which has already been approved up to bid Window 5 (BW5). As such, an expansion of the 400kV and 132kV bays are required. The project will involve the extension of the existing 400 kV yard by one bay, installation of a 400/132 kV 500 MVA transformer, extension of 132kV yard by seven bays, equipment of one 132kV transformer bay, relocation of the existing oil dam, and access road extension. This project forms part of an initiative to unlock grid capacity by connecting renewable energy generation by year 2027. The Eskom 2022 Transmission Development Plan (TDP) generation assumptions forecasts that 31 095 MW of PV and wind generation will be required nationally by 2030 of which 16 604 MW will be required as early as 2027. Currently there is limited or no capacity available in many of the Transmission supply areas.

The proposed project is located on Portion 3 of the farm Carthcarts Gift 311, within the Enoch Mgijima Local Municipality, Eastern Cape Province. The site is approximately 14km south west of Komani along the R67. The centre point of the site is 32° 0'41.18"S and 26°48'30.22"E. Please refer to attached project locality map
