South Africa’s Energy Crisis: Progress, But Risks Remain
Despite South Africa making strides in addressing its ongoing electricity crisis, load shedding remains a persistent threat. This past weekend, South Africans were left frustrated when load shedding returned abruptly, escalating from Stage 3 to Stage 6 within hours. According to the Minister of Electricity and Energy, Kgosientsho Ramokgopa, this was a necessary step due to Eskom’s aggressive maintenance plan. However, energy analysts warn that while improvements are being made, the system is still at risk due to a lack of reserve capacity.

Eskom’s Aggressive Maintenance Strategy
Ramokgopa defended the recent escalation of load shedding, stating that Eskom’s generation recovery plan required increased maintenance efforts. According to him, Eskom’s planned maintenance currently stands at 7,500MW, significantly higher than in previous years.
“We had to increase maintenance levels to ensure long-term reliability. While this decision comes with short-term risks, avoiding maintenance could result in catastrophic failures,” he explained.
Eskom implemented Stage 6 load shedding on Sunday at 1:30 AM, following unit failures at Majuba and Medupi power stations, which led to a loss of 3,864MW in generation capacity. This, combined with the ongoing maintenance efforts, created the need for emergency measures.
Why Load Shedding Risks Persist
Energy expert Ruse Moleshe emphasized that despite recent progress, South Africa’s power system remains vulnerable. The primary reason is the lack of reserve capacity—a critical safety net that should provide backup power in case of unexpected outages.
“While we are moving in the right direction, we still don’t have enough reserve capacity. This means that if any major plant fails, we have no immediate backup to prevent load shedding,” Moleshe warned.
She also highlighted that Eskom typically conducts most of its maintenance in summer, further reducing available electricity supply. This planned downtime, while essential for long-term sustainability, increases the risk of load shedding in the short term.
The Importance of Balance-of-Plant Maintenance
Energy expert Chris Yelland echoed similar concerns but acknowledged that Eskom was making progress. He stressed that Eskom had been focusing on generators and turbines, but balance-of-plant maintenance was just as crucial.
“Eskom must now shift focus to maintaining the entire power plant infrastructure, not just the main generation units. This will help improve overall efficiency and reliability,” Yelland advised.
While it is reassuring that the recent issues were related to balance-of-plant systems rather than core turbines, the absence of a solid reserve capacity means that any breakdown could still trigger severe load shedding.
Municipal Debt & The Role of Private Energy
Wayne Duvenage, CEO of Organisation Undoing Tax Abuse (OUTA), pointed out that municipal debt remains a major issue in Eskom’s struggles. Many municipalities owe billions to Eskom, and without these payments, the power utility struggles to fund critical repairs and maintenance.
“Municipalities must be held accountable for their debts. The government cannot continue to shield them while Eskom is trying to recover,” Duvenage stated.
Meanwhile, Business Unity South Africa’s (BUSA) Energy and Environment Director, Happy Khambule, highlighted the urgent need for additional power-generation sources, particularly private sector investment. He believes that opening the energy sector to independent power producers (IPPs) will help reduce dependence on Eskom’s struggling infrastructure.
“South Africa needs more energy sources, especially from private companies. This will help stabilize supply and reduce the burden on Eskom,” Khambule explained.
Will Load Shedding End Anytime Soon?
While Ramokgopa remains optimistic that Eskom’s maintenance strategy will ultimately result in a more stable grid, energy experts caution that load shedding is far from over.
Although Eskom expects the system to return to normal within the week, the lack of reserve capacity, municipal debt, and the slow integration of private energy solutions mean that South Africa remains vulnerable to sudden power outages.
Key Takeaways:
✅ Eskom’s aggressive maintenance plan is necessary but increases short-term load shedding risks.
✅ Reserve capacity remains critically low, making the system vulnerable to unexpected breakdowns.
✅ Municipal debt continues to strain Eskom’s ability to maintain infrastructure.
✅ Private sector energy investment is needed to stabilize South Africa’s electricity supply.
For now, South Africans must brace for continued power cuts, with hopes that Eskom’s long-term strategy will eventually provide much-needed relief. However, without structural reforms and additional energy sources, the risks of stage 6 or higher load shedding will persist.
