Johannesburg - The power system is expected to be constrained for the rest of the week, Eskom said on Tuesday.
“If we have technical faults, we would load-shed... We are, however, doing everything to keep the system intact,” said Eskom spokesman Khulu Phasiwe.
The power utility is struggling to keep the lights on due to faulty power plants and downtime due to maintenance.
Last month, Eskom chief executive Tshediso Matona was suspended, along with three other executives, pending an inquiry.
Matona has since taken his case to the Commission of Conciliation, Mediation and Arbitration (CCMA).
The three executives are finance director Tsholofelo Molefe, group capital executive Dan Morokane and commercial and technology executive Matshela Koko.
Board chairman Zola Tsotsi was recently replaced by Ben Ngubane.
