Eskom board chairperson Jabu Mabuza said that Eskom would implement stage one load shedding tomorrow and did not foresee the need for further power cuts thereafter.
He was briefing the media on the state of the power utility after it implemented load shedding on Wednesday due to faulty generating units.
Friday's load shedding will be implemented from 9am and will end at 11pm.
Meanwhile Deputy President David Mabuza has apologised to South African businesses and school learners for the latest round of load shedding.
A number of businesses have been affected by the blackouts as well as learners who are busy writing their end of year examinations across the country.
He was responding to oral questions in the National Assembly this afternoon.
