South Africa has achieved a major milestone in its energy sector as Kusile Power Station has finally reached full commercial capacity after more than a decade of challenges. The completion of its final unit in September 2025 has brought the plant’s total capacity to 4,800 megawatts, making it one of the largest power stations in the country. Along with its sister plant, Medupi, the two facilities now contribute a combined 9,600 megawatts, forming a critical part of the national electricity grid.
President Cyril Ramaphosa recently visited the power station to mark the occasion, calling it an important step forward for the country’s energy security. He praised the efforts of workers and noted that the station has been performing well, with some units achieving an energy availability factor of up to 90%. This improved performance has helped South Africa experience close to a full year without load shedding, offering much-needed relief to businesses and households that have struggled with frequent power cuts in the past.
Despite this progress, the journey to completion has been marked by serious financial and governance issues. The Kusile project was initially estimated to cost around R80 billion, but the final cost has risen to more than R160 billion. When combined with similar overruns at the Medupi power station, the total excess cost has crossed R300 billion. These rising expenses have placed significant pressure on Eskom, the country’s main power utility.
The project also faced an 11-year delay due to multiple challenges, including design problems, labor unrest, and technical failures. One of the most serious incidents was the collapse of a major chimney in 2022, which further slowed construction. In addition, investigations by the State Capture Commission and parliamentary committees revealed widespread corruption and irregularities in procurement during the building phase.
President Ramaphosa acknowledged these issues and described them as important lessons for future infrastructure projects. He stressed the need for better governance and accountability to avoid similar problems. At the same time, he emphasized that Kusile is now a valuable national asset that will play a key role in stabilizing the country’s electricity supply.
Government officials believe that despite its troubled history and high costs, the power station will help restore investor confidence and support long-term economic growth. As South Africa continues to reform its energy sector, Kusile Power Station stands as both a symbol of progress and a reminder of the risks associated with large-scale public projects.
