Eskom Repairs Three Units, Builds Up Diesel and Water

South Africa's Eskom was able to repair three out-of-service units and build up its diesel and water reserves after instituting rolling black-outs over the weekend, the state-owned power utility said on Monday.

The move restored much-needed power back into South Africa's ailing grid although the utility said supply would remain tight.

"The electricity system will remain constrained this week requiring use of emergency reserves (water and diesel power plants) to meet demand especially during peak hours," Eskom said in a statement.
