Eskom has successfully integrated Unit 6 of the Kusile Power Station into the national grid, a significant step in boosting South Africa’s electricity generation capacity.
The unit was synchronised on Sunday at 16:45, bringing Eskom closer to finalising one of the country’s most ambitious infrastructure projects.
Once fully operational, Kusile Power Station will contribute 4,800MW to the grid, making it the largest infrastructure project in South Africa.
This development also aligns with Eskom’s broader goal of adding 2,500MW of new capacity by March 2025.
In addition to progress at Kusile, Eskom confirmed that Unit 4 of the Medupi Power Station is expected to return 800MW to the grid by the end of April 2025. This unit had been offline due to a generator stator failure.
Kusile is the first power station in South Africa and on the continent to use wet flue gas desulfurisation technology, a method that reduces sulphur dioxide emissions and ensures compliance with international air quality standards.
Eskom noted that the successful synchronisation of Unit 6 reflects the dedication of its workforce and partners, despite facing numerous challenges.
The unit will now undergo a series of tests and optimisation procedures over the next six months before entering full commercial operation. Once this is achieved, its full 800MW capacity will be officially added to the national grid.
The power utility reaffirmed that this milestone contributes to stabilising the country’s electricity supply and meeting the targets set out in its Generation Recovery Plan.
It also forms part of Eskom’s longer-term strategy to improve operational performance, support economic growth, and establish a more reliable and sustainable energy system.
Eskom concluded by highlighting its commitment to strengthening governance, executing its recovery initiatives, and ensuring long-term energy security for both South Africa and the wider sub-Saharan region.
