“Stage 2 load-shedding will be implemented at 21:00 tonight until 05:00 on Monday in order to replenish emergency generation reserves for the week ahead,” said the power utility in a tweet.
Eskom said “over the past week there have been multiple breakdowns and trips , including those at Tutuka, Kriel, Hendrina, Kusile, Arnot and Kendal power stations.”
The power utility said total breakdowns amount to 15 627 MW, while planned maintenance was at 4 954 MW capacity.
Eskom, which said it had been relying on emergency generation reserves, which were now very low.
“These now need to be replenished in order to increase available capacity for the week ahead,” said Eskom.
