Seriti Green officially handed the Vunumoya main transmission station MTS to Eskom on November 26 at the site near Bethal, Mpumalanga, completing a privately built 400/132 kV substation designed as the primary grid injection point for the 900 MW Ummbila Emoyeni renewable energy programme.
Constructed over 17-18 months, the station includes a 500 MVA 400/132 kV transformer and is designed to accommodate a second 500 MVA unit with the first transformer installed and energised as part of the initial phase. The facility also comprises fully equipped 400 kV and 132 kV yard infrastructure and space for additional feeders to support future load growth.
Seriti Green CEO Peter Venn said the project demonstrates how private developers can accelerate transmission delivery in constrained areas.
