Johannesburg - South African state-run power utility Eskom said its second unit at the Koeberg plant was back in commission but that electricity supply would remain tight over the next few days.

The unit was shut down on March 23 for scheduled maintenance.

“The system is tight for tonight over the evening peak, and is expected to remain tight over the evening peaks for the next few days due to higher demand with the colder weather conditions,” Eskom said in a statement. - Reuters
