Cape Town -  South Africans have been urged to use electricity sparingly as the country's power utility grapples with wildcat strikes, which Eskom said could result in rotational load-shedding during the morning peak period on Tuesday.

"Customers are advised to keep checking their load shedding schedules on the Eskom or municipal website, and plan on the assumption that load shedding will take place," the state-owned company said in a statement.

"Loadshedding is conducted rotationally as a measure of last resort to protect the power system from a total collapse or blackout."

The power supplier said it would advise the public whether it required stage 1, stage 2, stage 3 or stage 4 loadshedding, depending on the capacity shortage during the morning peak.

"Stage 1 requires 1000MW to be rotationally loadshed nation-wide, stage 2 requires 2000MW, stage 3 requires 3000MW and stage 4 calls for up to 4000MW to be rotationally loadshed nationally at a given period."

Eskom said it was talking to union leaders to try and negotiate an end to the impasse with workers.

Employees are demanding 12 percent of their annual salaries as a once-off bonus as part of a wage settlement which has yet to be concluded two months after negotiations between unions and the cash-strapped utility started.
