Floods in southern Mozambique have cut power exports to energy-hungry neighbour South Africa in half, an official said on Thursday.
Key power lines to South Africa were damaged by the flooding of the Limpopo River, Hilary Joffe, a spokesperson for South Africa's energy giant Eskom, told AFP.
"That has meant the supplies from Mozambique have been reduced. We are getting much less than 650 MW... which is less than half of what it should be," she said.
Eskom imports between 1 300 MW and 1 500 MW of electricity from Hidroelectrica de Cahora Bassa (HCB), the operators of one of Africa's largest hydro-electric projects.
The line gave in to raging flood waters that have submerged parts of Mozambique this week.
Work is underway to fix the transmission line, and South Africa is helping its impoverished neighbour with the repair works, the Eskom spokeswoman said.
In the meantime, the group is getting electricity from other providers to avoid brownouts.
The floods have forced Mozambique authorities to evacuate tens of thousands of people.
