Market context
Local grid, utilities, climate and procurement.
Johannesburg sits at 1,753 m elevation on the Witwatersrand and is supplied by City Power (the municipal utility) plus Eskom for transmission and a portion of bulk distribution. The grid runs 11/22 kV at MV and 88/132/275/400 kV at transmission, with the Apollo-Hydra HVDC link (1,920 MW) bringing Cahora Bassa hydropower from Mozambique. South Africa's chronic load-shedding (Stage 6 = 6,000 MW deficit) drives unprecedented demand for behind-the-meter generation, captive solar GSU transformers, mobile substations and emergency diesel-genset MV switchgear. Specifications follow NRS 002/004 (NRS = National Rationalised Specifications, derived from IEC 60076) with high-altitude derating ≥1,500 m and lightning-impulse-tested bushings (frequent thunderstorms in summer). Procurement is shaped by Eskom's 14 GW Just Energy Transition pipeline, the Special Risk Insurance reforms enabling private wheeling, and the Sasol Secunda gas-to-liquids complex. Tender hints: NERSA licensing and SABS-marked equipment are mandatory; ETS supplies through Durban-port logistics.
