Repowering coal power stations
Komati is the first of Eskom’s coal stations to stop operating. Eskom’s plans to repower and repurpose Komati include a solar facility and battery storage. There is also a trade school, an aquaponics pilot facility and a project to produce containerised solar power for remote off-grid communities. Projects to help cushion the shock to the community, provide skills training and offer new types of jobs.
But the station closed before any of those projects got off the ground. Komati is one of six older power stations where repowering projects have been approved as part of Eskom’s Just Energy Transition strategy. The others are at Grootvlei, Arnot, Camden, Hendrina and Kriel power stations. Camden, Hendrina, Grootvlei and Arnot will continue operating until 2030 “to support energy security”, says Eskom. The “repowering and repurposing” (R&R as Eskom calls it) projects, however, will continue independently, not wait till the coal stations are decommissioned.
In its 2025 Integrated Report, Eskom says it plans to add 3 233 MW of renewable capacity through solar PV, wind, battery storage and synchronous condensers in the next four years, leveraging existing grid infrastructure. It also estimates the programme will create 1 800 permanent and 16 000 temporary jobs, primarily in the renewable energy and manufacturing industries.
