Big boost for Eskom’s fight against load shedding

Power utility Eskom has announced that unit 5 of the Kusile power stations has reached commercial operation, and will add 800MW to the grid.
The unit was first synchronised to the grid at the end of 2023, which signalled the start of rigorous testing and optimisation.
The unit will now begin contributing power, increasing Kusile Power Station’s total output to 4,000MW.
“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 through its nature,” said Isabel Fick, General Manager System Operator.
Eskom said that the additional megawatts would further cement the stable operation of the grid seen over the past 93 days, where load shedding has been suspended.
Dan Marokane, Eskom Group Chief Executive said the additional generating capacity is part of the 2,500MW expected to come online before the end of the calendar year (ie, December 2024).
“Eskom will continue to focus on implementing operational recovery, strengthening governance and future-proofing the organisation to enable energy security, growth and long-term sustainability to the benefit of South Africa and sub-Saharan Africa,” he said.
Over the past six months, Kusile Power Station Unit 5 has undergone a series of tests while intermittently supplying electricity. Since its synchronisation in December 2023, the unit has met performance expectations, supported the grid and helped to reduce load shedding.
Upon completion, Kusile Power Station will consist of six units, producing a maximum of 4,800MW.
Construction of the remaining Kusile Unit 6 is progressing as planned, with it expected to be synchronised to the grid in November 2024.
Additionally, Kusile is equipped with wet flue gas desulphurisation (WFGD) technology, making it the first power station in South Africa and Africa to use this emissions abatement technology.
WFGD removes sulphur dioxide from flue gas before it is released into the atmosphere, ensuring compliance with international air quality standards.
