1. Transmission power line lengths as per Geographic Information System (GIS) distances.
2. The Majuba Umfolozi No 1 (765kV line), even though constructed at 765kV, is currently still being operated at 400kV and thus, for now, is
reflected under the 400kV total.
3. Restated comparatives.
4. Base of definition: transformers rated ≥ 30 MVA and primary voltage ≥132 kV.
