There is high probability for stage 2 load shedding on Sunday, Eskom said in a statement.
The power utility implemented stage 1 load shedding on Saturday- between 09:00 and 22:00.
In a statement issued later on Saturday evening, the power utility said that increased breakdowns at power stations had further impacted the availability of sufficient generation capacity.
"As a result, we have been unable to build up the necessary reserve for the week ahead.
"We therefore regret to announce that stage 2 load shedding remains a high probability for tomorrow (Sunday)," the statement read.
The power utility said that there is also a high probability for stage 2 load shedding on Monday.
