Power stations are supposed to have enough coal to keep the lights on for 20 days.
The power utility said on Friday during a media briefing that it will transport 1.4 Mt (million tons) of coal by train per year from Medupi to the 10 affected power stations from next month.
The affected Mpumalanga power stations are Arnot, Camden, Duvha, Hendrina, Komati, Kriel, Kendal, Majuba, Matla and Tutuka.
“While we have a recovery plan, load-shedding cannot be ruled out for the remainder of 2018,” Eskom said.
Eskom implemented emergency stage one load-shedding on Sunday before it was suspended at 7pm.
