Southern Africa Probes Blackout That Affected Four Countries

Power companies in southern Africa are investigating the cause of an “unprecedented” system disruption that affected four countries.

Zambia suffered a nationwide blackout on Nov. 6, while neighboring Zimbabwe reported on Nov. 8 that a technical fault at one of its main power plants had curbed supply. The disturbance also resulted in a loss of connection between South Africa and Mozambique’s Cahora Bassa hydropower plant, said Stephen Dihwa, executive director of the Southern African Power Pool.
