Eskom says it will implement stage four load shedding from 12:00 on Wednesday until 05:00 on Friday, thereafter stage two load shedding will continue as previously communicated until 05:00 on Saturday.

This is due to a shortage of generation capacity.  Over the past 24 hours, a unit each at Medupi, Kusile and Matla power stations tripped while a unit each at Lethabo and Arnot power stations were forced to shut down.

In a statement, Eskom says, “This constrained the power system further requiring extensive use of emergency reserves and therefore, hampering the recovery of these reserves.”

“Some generating units have returned to service and we anticipate another two units to return to service during the day. In addition, Koeberg 1 is expected to return to service today (Wednesday) and begin ramping up for full output within 48 hours.”

On Tuesday, the City of Johannesburg admitted to a strained relationship with Eskom, despite sourcing additional private electricity.
