UPDATE: Eskom has escalated load shedding to stage 2 in some areas due to high demand or urgent maintenance being performed at certain power stations.
Johannesburg - Power utility Eskom has once again implemented load shedding until three generators are fixed, a spokesperson said on Monday.
"We have started with stage one of load shedding," spokesperson Andrew Etzinger said.
"Three large generators at our power stations are out of service."
Eskom earlier said supplies at its pump storage power stations have been restored and there would be no load shedding during the week following a weekend that saw stage three load shedding being implemented.
Many areas in the country were without power for most parts of the weekend as the power utility and its municipal customers implemented rostered blackouts to save power reserves for the week.
Etzinger said the cuts would last for most of Monday but as soon as the generators were back on line "things should be better".
