Eskom is implementing Stage 2 load-shedding from 16:00 to 24:00 on Wednesday and Thursday.  “The delay in returning a generation unit to service each at Arnot, Koeberg and the Kusile power stations, as well as the unplanned outage of a generation unit each at Camden, Medupi and two units each at Grootvlei, Hendrina and Majuba power stations, have exacerbated the capacity constraints,” Eskom said.
