6.4.4 PRETORIA CLN
Strengthening of the Tshwane Metro network is necessary to ensure adequate capacity for the city’s development.
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:
