Due to lower weekend demand, loadshedding will be suspended at midnight on Friday, Eskom says.

Since Wednesday evening, a generation unit each at Arnot and Majuba power stations were returned to service, while a generating unit each at Duvha, Hendrina, Lethabo and Tutuka power stations were taken offline for repairs.

"We currently have 5 254 MW on planned maintenance, while another 15 190 MW of capacity is unavailable due to breakdowns," Eskom points out.

Eskom says it will publish a further update on Sunday afternoon or as soon as any significant changes occur.
