The situation at Eskom is normalising as workers have heeded the call to report for duty.

The National Union of Mineworkers (NUM) says its members have reported that there are no pickets at the power stations in Mpumalanga.

It comes as Eskom and unions have returned to the wage negotiating table with a new offer expected to be officially tabled this week.

Last week some workers embarked on an unprotected strike to express their unhappiness about the collapse of the wage talks. The strike has been marred by allegations of intimidation.

Eskom has blamed the industrial action for the surge in load shedding. But it has also experienced a number of generation unit breakdowns.

On Monday South Africa had to endure Stage 6 power cuts for six hours. During the others parts of the day the rolling blackouts were at Stage 4. Eskom has indicated that a similar situation will play out today with Stage 6 kicking at 4pm until 10pm tonight.
