Eskom has confirmed that Unit 3 at the Kusile coal-fired power station is currently providing 720 MW into the electricity grid using a temporary flue that bypasses the flue-gas desulphurisation (FGD) pollution control system. Unit 3 was restarted on September 30, just short of a year after it as well as units one and two became inoperable on October 23, 2022, after a slurry build-up in the Unit 1 flue led to its collapse, damaging the other two flues in the west chimney they share in the process.
