Eskom has taken a significant step towards improving South Africa’s energy stability with the successful addition of 800MW from Kusile Power Station’s final generation unit. The new unit, which came online on Sunday at 4:45 PM, marks a crucial milestone in Eskom’s efforts to strengthen the national electricity supply as winter approaches.

A Crucial Addition to the Grid
The completion of Kusile Power Station’s Unit 6 brings Eskom closer to achieving its goal of adding 2,500MW of new capacity to the grid by March 2025. This progress comes at a critical time when the power utility is still recovering from prolonged power shortages and the persistent challenge of load shedding.
Eskom CEO Dan Marokane emphasized that Kusile Unit 6’s successful activation is proof of Eskom’s commitment to stabilizing and reinforcing the country’s energy supply. He assured South Africans that Eskom is working hard to avoid a return to the severe load shedding levels experienced in 2023.
Testing Phase and Full Integration
Despite its addition to the grid, Kusile Unit 6 will undergo six months of rigorous testing before it is officially integrated into Eskom’s permanent generation fleet. Eskom spokesperson Daphne Mokwena stated that this testing phase is essential to ensure the unit’s reliability and efficiency before it becomes a fully operational part of South Africa’s electricity supply.
Once all Kusile units are fully functional, the power station will contribute a total of 4,800MW to the grid, making it the largest infrastructure project in South Africa. Kusile’s sister station, Medupi, is also undergoing improvements, with its Unit 4 expected to return 800MW by April 2025 after an extended outage due to a generator stator failure.
Eskom’s Grid Remains Constrained
Despite this boost in generation capacity, Eskom’s power grid remains constrained. The utility’s Group Executive for Generation, Bheki Nxumalo, acknowledged that while the activation of Kusile Unit 6 is a major achievement, Eskom must continue working on strengthening South Africa’s energy security. The focus is now on ensuring that the unit achieves full commercial operation by the second half of 2025.
South Africans have faced frequent power cuts over the past few years, and while this new capacity is a step in the right direction, Eskom remains under pressure to address its generation shortfalls and grid challenges.
A Step Towards Cleaner Energy
Kusile Power Station is not only one of the country’s largest energy projects but also the first in Africa to implement Wet Flue Gas Desulphurisation (WFGD) technology. This system helps reduce sulphur dioxide emissions, ensuring compliance with air quality standards and aligning with global best practices. This move reflects Eskom’s commitment to environmentally friendly energy production while addressing South Africa’s electricity crisis.
Looking Ahead: Can Eskom End Load Shedding?
While Kusile’s latest addition provides much-needed relief, energy experts warn that South Africa is still not out of the woods. Eskom continues to struggle with aging infrastructure, unplanned outages, and maintenance backlogs. The power utility’s ability to consistently generate and distribute electricity without interruptions remains a concern.
However, Eskom’s leadership is confident that their ongoing projects, including planned maintenance and infrastructure expansion, will help reduce load shedding in the long run. With Kusile Power Station nearing completion and Medupi’s upgrades underway, Eskom aims to improve grid stability and provide a more sustainable electricity supply for South Africans.
The addition of 800MW from Kusile Unit 6 is a significant victory for Eskom and a much-needed boost for South Africa’s energy grid. While it signals progress, the utility must remain focused on long-term stability and consistent energy production to fully eliminate load shedding.
With more units expected to return online in the coming months, South Africans can hope for fewer disruptions—but only time will tell if Eskom can truly keep the lights on.
