Eskom will implement rolling power cuts from 12:00 to 22:00 on Wednesday, the power utility said on its official Twitter page.
The state-owned power utility said it would cut 2 000 megawatts of electricity from the strained grid.
Africa’s most advanced economy is in the midst of its worst electricity crisis since 2008 and Eskom implements frequent power cuts to prevent the national grid from being overwhelmed.
