Eskom says it is on track for permanent repair of Kusile stack by Dec

Eskom insists it is on track to complete the repairs to the ducts in the west stack at the Kusile power station by December 2024, ahead of the March 31, 2025, deadline set by the Department of Forestry, Fisheries and the Environment (DFFE) when it last year authorised the use of temporary stacks that bypass the key pollution control system. The west stack was rendered inoperable when Kusile’s Unit 1 flue duct collapsed because of an uncontrolled build-up of slurry on October 23, 2022. The failure eliminated 2 100 MW of Kusile’s capacity from an already stretched system, as units 2 and 3’s flues, which share a stack or chimney with that of Unit 1, were also damaged by the collapse.
