Eskom has officially transferred Unit 5 of the Kusile power station to its Generation division, following six months of rigorous testing and optimisation. This unit will now contribute to increasing Kusile's total output to 4,000 MW.

Since its synchronisation in December 2023, Kusile Unit 5 has undergone a series of tests, intermittently supplying electricity to the grid. The unit has met performance expectations, bolstered the grid, and helped alleviate loadshedding.

“Kusile Unit 5 makes an extremely valuable contribution to the national grid. Not only is it one of the largest baseload units contributing megawatts, but it also enhances the stability of the network,” said Eskom system operator GM Isabel Fick.

The integration of this generation unit marks a significant milestone in Eskom’s efforts to stabilise South Africa’s power system.

“The delivery of the unit, as part of our Generation Operational Recovery Plan, showcases the remarkable achievements possible when our 40,000 employees work together as a collective. This achievement aligns with our commitment to maximising grid capacity,” said Eskom Generation group executive Bheki Nxumalo.

Eskom Group CEO Dan Marokane highlighted the strategic importance of this addition. “On April 26, in our winter outlook, we said we would add new generation capacity to the grid with Kusile power station Unit 5, as part of our intense focus on delivering the Generation Operational Recovery Plan. This addition is part of a total of 2,500 MW that will be added before the end of this calendar year.”

Marokane further emphasized Eskom’s commitment to operational recovery, governance strengthening, and future-proofing the organisation to ensure energy security, growth, and long-term sustainability for South Africa.

Located near eMalahleni in Mpumalanga, Kusile power station, upon completion, will consist of six units producing a maximum of 4,800 MW, making it the world’s fourth-largest coal plant. Construction of the remaining Kusile Unit 6 is progressing as planned, with synchronisation to the grid expected in November.

Kusile is equipped with wet flue gas desulphurisation (WFGD) technology, the first in South Africa and Africa to use this emissions-abatement method. WFGD removes sulphur dioxide from flue gas before it is released into the atmosphere, ensuring compliance with international air quality standards.
