State-owned electricity utility Eskom has not shifted its April 9 deadline for returning Medupi Unit 3 to service, despite work restrictions imposed at the Lephalale site, in Limpopo, in response to the Covid-19 pandemic. The unit was shut for 75 days on January 26 to address defects that emerged, mostly in relation to the boiler, after the unit entered into commercial operation in June last year.
