According to Sapa, around 07:30, however, the Eskom load shedding website still bore the warning: "Eskom is currently load shedding in stage two".
The stage two power cut plan aims at saving up to 2000MW.
Spokesperson Andrew Etzinger was not immediately available for comment.
Sapa reported that at 06:00 on Thursday Eskom announced a power emergency caused by heavy rains, which wet its coal stocks.
Large industrial customers were asked to reduce consumption by 10% and the public were asked to conserve electricity to help ease demand on the power grid.
In Tshwane, power was cut for about two hours on Thursday. The areas affected included Waterkloof, Pumulani, Koedoespoort, Tonnel, Mayville, Highlands, Soshanguve, Montana, Rosslyn, and Pretoria North.
Johannesburg's affected areas included Hillbrow, Berea, Houghton, Parktown, Rosebank, Hyde Park, Inanda, Alexandra, Rembrandt Park, Sunningdale, and Lombardy.
The City of Cape Town initiated "stage three" power cuts and suburbs in Port Elizabeth were also affected by it.
On Friday morning, Johannesburg City Power issued a load shedding schedule as a precaution.
Spokesperson Sol Masolo said: "As we speak, now there is no load shedding. We have the schedule just in case [the emergency resumes]".
