Transmission network injections will be needed at Tshwane Metro’s existing Buffel supply point and Wildebees. The other substations supplying Tshwane Metro will also experience load growth, namely, Kwagga, Njala, and Verwoerdburg. The projects in the Pretoria CLN are as follows: Tshwane Metro Strengthening • Establishing 400/275/132kV substation at Phoebus 2013 • Establishing 400kV busbar at Phoebus 2013 • 1x250MVA, 400/132kV line bank to Hangklip at Phoebus 2013 • 1x400MVA, 400/275kV line bank to Pelly at Phoebus 2013 • Operate the Hangklip-Pelly 132kV line to Phoebus-Pelly at 275kV 2013 • Loop in-out Apollo-Dinaledi 400kV line into Phoebus 2013 • Establish 400kV busbar at Wildebees 2014 • Loop in and out Apollo-Phoebus 400kV line at Wildebees 2014 • Establish 400kV busbar at Verwoerdburg 2012 • Loop in and out Apollo-Pluto 400kV line at Verwoerdburg 2012 • 2x250MVA, 400/132kV transformers at Verwoerdburg 2012 • 1X275kV line from Lomond to Kwagga 2013 • Verwoerdburg 3rd 250MVA, 400/132kV transformer 2017 Transmission Ten-Year Plan 2011-2020
