Dark Days Ahead for South Africa as Eskom’s Load Shedding Crisis Looms

South Africa’s energy crisis has taken a grim turn as experts warn that load shedding is far from over. Despite a brief reprieve, Eskom’s unreliable generation capacity and structural issues continue to threaten the country’s power stability, with rolling blackouts likely to return as winter approaches.

The recent implementation of Stage 6 load shedding on February 23, 2025, served as a stark reminder of the fragility of South Africa’s energy grid. The crisis, triggered by multiple unit failures at the Camden Power Station, removed 6,000 megawatts from the grid, plunging the nation into darkness. Although Eskom managed to suspend load shedding by February 26 after recovering some capacity and replenishing emergency reserves, doubts about the utility’s turnaround efforts persist.

A Crisis of Transparency and Reliability

Energy consultancy EE Business Intelligence highlighted that Eskom’s public communications downplayed the severity of the crisis before the sudden surge in power cuts. The abrupt loss of significant generating capacity—3,600 MW from Majuba, 800 MW from Medupi, and 800 MW from Camden—without prior warning has raised concerns about Eskom’s operational transparency.

While some critics attributed the high levels of load shedding to cloudy weather reducing renewable energy generation, Minister of Electricity Kgosientsho Ramokgopa dismissed these claims, pointing instead to deeper structural issues within Eskom. “The problem lies in the fundamental inefficiencies of our aging infrastructure,” he stated.

Winter Woes and Unreliable Coal Fleet

Energy analyst Chris Yelland emphasized that the return of Stage 6 load shedding underscores the erratic and unreliable nature of South Africa’s coal-fired power generation. “At around 80%, there is far too much coal-fired power in our mix, which poses a significant risk to the economy,” Yelland warned. He stressed that unless Eskom addresses its core issues, further power disruptions are inevitable.

Robert Futter, executive director at Cresco, acknowledged that Eskom has managed to balance supply and demand through measures like diesel-powered peaking stations and load-curtailment agreements with large consumers. However, he cautioned that these solutions are unsustainable. “Many large users are on special contracts with Eskom, and for Eskom, that is probably the easiest way to balance the grid,” Futter said. He expressed particular concern about the upcoming winter months, when energy demand typically rises while more generating units undergo planned maintenance.

Futter likened Eskom’s aging coal fleet to an old Land Rover Defender—built for endurance but prone to breakdowns with continuous use. “We hope these old power stations will continue to operate well, but increased breakdowns could lead to further load shedding this year,” he warned.

A Fragile Grid and Long-Term Challenges

Energy analyst Professor Hartmut Winkler echoed these concerns, noting that South Africans should expect intermittent power cuts to continue for the next two to three years. “We were very lucky over the last year that we went so long without load shedding,” Winkler said. He explained that Eskom has been “walking close to the line,” meaning any unexpected disruption could easily trigger power cuts.

A recent example of this vulnerability occurred on March 2, when Eskom announced that the national grid remained under strain following the unexpected trip of Koeberg Unit 2. The nuclear reactor, operating at full capacity, was forced offline due to an unplanned, non-technical incident. While this did not immediately result in load shedding, Eskom acknowledged that overall generation capacity remains constrained.

Maintenance Efforts and Lingering Doubts

Eskom has maintained high levels of maintenance, averaging 7,032 MW in February, in an effort to improve fleet reliability ahead of winter. However, questions remain about whether these efforts will be sufficient to prevent further power disruptions. With the onset of winter and the increased strain on the grid, South Africa’s energy stability hangs in the balance.

A Call for Long-Term Solutions

As the nation braces for potential dark days ahead, the need for long-term solutions to South Africa’s energy crisis has never been more urgent. Experts agree that Eskom must address its structural inefficiencies, diversify its energy mix, and invest in sustainable infrastructure to ensure a stable power supply for the future.

For now, South Africans must prepare for the possibility of more load shedding, as Eskom’s challenges continue to cast a shadow over the country’s energy landscape.
