The power utility is currently experiencing huge cost overruns, ailing infrastructure at some of its power stations and frequent electricity outages.
De Ruyter is likely to shed light on how the grid will accommodate Independent Power Producers.
The media briefing will also be the first this year without the former chairperson of the Eskom boardJabu Mabuza.
South Africans will hear if Eskom will be able to keep the lights on in the coming months.
South Africans have been hit hard by frequent load shedding despite government and the power utility reassuring the public that power cuts will be resolved. This month the power utility published new schedules for load shedding.

Meanwhile, Eskom’sstage 2 load sheddingwill continue at nine o’clock on Friday morning as the system remains tight.
