Overview
- The move completes the 12‑unit Kusile–Medupi fleet, which Eskom says can provide up to 9,600MW when fully available.
- Unit 6 was synchronized on 23 March 2025 and supplied power during testing but its output was excluded from official figures until now.
- Eskom frames the milestone as part of its Generation Operational Recovery Plan, saying the unit met benchmarks and contributed to demand 97% of the time since March.
- Kusile is described as the first plant in South Africa and on the continent to use wet flue gas desulphurisation to curb sulphur dioxide emissions.
- The achievement comes after years of delays and cost overruns highlighted by energy specialist Anton Eberhard, with corruption prosecutions related to Kusile upgrade contracts still under way.
