Eskom has stopped supplying electricity to neighbouring countries amid the dire shortage in South Africa, it said on Sunday.
The power company only sold electricity when it had a surplus, said spokesperson Sipho Neke.
Of the electricity generated by Eskom, 95 percent is used locally. The rest is exported to Botswana, Namibia and Zimbabwe.
The country’s electricity crisis was debated at length during the African National Congress’s three-day meeting, which closed in Midrand on Sunday, said the party’s secretary-general Gwede Mantashe.
President Thabo Mbeki will meet this week with Eskom management to ascertain the extent of the problem and the company’s remedial plans.
