South African state power utility Eskom said it was extending rotational power cuts until Monday due to plant breakdowns causing a persistent shortage of generation capacity.

Eskom said it would implement "Stage 4" power cuts until 05:00 local time (0300 GMT) on Sunday, and thereafter "Stage 3" until 05:00 on Monday.

Stage 4 and Stage 3 outages require up to 4,000 megawatts (MW) and 3,000 MW to be shed from the grid, respectively.
