While challenges remain, Eskom’s drive to modernize and clean up its act is lighting the way toward a steadier and brighter future. This winter, South Africa might finally turn a corner away from darkness.
Will Eskom end loadshedding in Winter 2025?
Eskom’s Winter 2025 outlook shows significant improvements with unplanned outages reduced to 13-15GW, limiting loadshedding to about 21 days. Key factors include stricter maintenance, smart grid technology, and new power units, offering South Africans a more stable and reliable electricity supply this winter.
Shifting from Crisis to Confidence
South African winters have long been synonymous with power outages, plunging cities like Johannesburg and Cape Town into darkness. For years, the arrival of cold weather signaled a scramble for candles and the relentless noise of backup generators. Yet, in 2025, Eskom presents a hopeful new narrative. The nation’s electricity giant recently delivered its winter outlook, fueling cautious optimism among households and businesses alike. After a year marked by strategic changes and consistent improvements, Eskom’s message signals a remarkable departure from the anxieties of previous years.
At the heart of this positive forecast lies Eskom’s aggressive campaign against unplanned maintenance. If unexpected outages stay below 13 gigawatts (GW), the country could see its most reliable winter in over a decade. Eskom’s contingency planning even accounts for an increase in breakdowns—up to 15GW—yet expects loadshedding to top out at just 21 days during the 153-day winter period. This marks a clear improvement over last year’s situation, when the threat of Stage 5 loadshedding loomed large. In fact, unplanned outages have fallen by 3.1GW in just twelve months, with forecasts narrowing to a far more manageable 13-15GW, compared to last year’s broader and riskier 14-17GW range.
Eskom’s Group Chief Executive, Dan Marokane, stands at the forefront of this turnaround. His leadership and focus on restoring operational discipline have been central to Eskom’s progress. During the prior financial year, Eskom delivered electricity 96% of the time—a jaw-dropping leap from the mere 9.9% reliability that haunted the previous year. This improvement does more than boost statistics; it restores a sense of stability and predictability to daily life, allowing families and businesses to plan ahead without living in constant fear of sudden outages.
Operational Discipline and Strategic Upgrades
Despite these victories, the shadow of loadshedding has not disappeared entirely. The first four months of 2025 still saw power interruptions, serving as a stark reminder of the power grid’s fragility. Marokane openly recognizes that vulnerabilities persist. However, Eskom’s approach has shifted from merely reacting to crises to implementing a proactive, integrated recovery plan. This new direction emphasizes rapid-response measures and strict adherence to operational protocols, aiming to halt minor issues before they escalate.
A significant part of Eskom’s progress comes from moving away from reliance on diesel-powered emergency generators. While these units once filled gaps during peak demand, they also drained resources and polluted the environment. Over the past year, Eskom managed to slash its diesel usage by nearly 50%, generating substantial savings—around R16 billion. This not only eases the strain on the national budget but also aligns the utility with global trends toward cleaner, more sustainable energy practices, echoing the broader movement toward green energy solutions.
Bheki Nxumalo, Eskom’s Group Executive for Generation, serves as another pillar of the power utility’s resurgence. He oversees the ambitious Generation Recovery Plan, aimed at modernizing ageing infrastructure and improving reliability. Eskom boosted its planned maintenance rate to 12.8% this year, up from last year’s 12%, with peak periods reaching 14.5% between September and March. These efforts have paid off handsomely; plant availability climbed to 61% during the 2024/25 fiscal year, a notable 6.5% increase over the previous year’s figures.
Modernization and Smart Grid Technology
Stepping inside Eskom’s control centers, one senses a profound transformation. Where panic and urgency once reigned, a more focused and confident atmosphere now prevails. Engineers at Eskom’s Megawatt Park headquarters recall the old days of constant emergencies, when every phone call brought news of another breakdown. Now, real-time monitoring screens display steady output and healthy reserves. “We are no longer just putting out fires,” one engineer remarks. “We’re finally staying ahead of the curve.”
Modern technology has played a central role in Eskom’s recovery. The rollout of 880,000 smart meters marks one of the utility’s most ambitious steps toward digitization. These advanced devices provide detailed, real-time insight into supply and demand trends, especially during peak hours. By quickly flagging abnormalities and enabling rapid intervention, smart meters have become the backbone of Eskom’s new, responsive grid management system. Their deployment recalls the revolutionary adoption of remote monitoring technologies in the early days of electric utilities, signaling a new era for South African power.
Key power stations have also returned to action, bolstering Eskom’s winter readiness. Koeberg Unit 2, South Africa’s only nuclear reactor, was brought back online in December 2024, adding over 900 megawatts of capacity to the grid. Kusile Unit 6 connected in March 2025 and is slated for commercial operation by September, while Medupi Unit 4 is expected to restore an additional 800 megawatts by the end of May. Each returning unit marks a step toward stability and echoes the massive infrastructure expansions of the mid-20th century, when nations built the foundations for modern economies.
Energy Transition and Resilience for the Future
South Africa’s rapidly growing cities and industries continue to put immense pressure on its power grid. Loadshedding has been much more than a mere inconvenience—it has shuttered factories, devastated small businesses, and forced families to adapt to an unpredictable reality. The economic and emotional toll cannot be overstated. Now, with Eskom’s improving performance, many South Africans dare to hope that this winter might be different.
Eskom’s transformation is taking place amid a global shift toward cleaner, more resilient energy systems. While the immediate priority remains keeping the lights on, the longer-term challenge involves embracing renewable energy sources. South Africa’s abundant sun and wind place it in an enviable position to transition toward a greener grid. In that context, smart meters and station upgrades are not just short-term fixes—they are investments in a future where Eskom can integrate renewables without sacrificing reliability.
Public trust in Eskom remains in recovery mode. Scandals, mismanagement, and crippling debt have left their mark, and skepticism lingers. Yet, evidence of progress is beginning to change perceptions. In township corner stores, resilient shop owners who once despaired over spoiled stock and lost revenue now listen for the constant hum of refrigerators, a sound they once feared would go silent. “Eskom is making an effort,” says one shopkeeper. “For the first time, I think we’ll get through winter with our doors open.”
Challenges persist, and the grid remains vulnerable to a variety of threats—from technical failures and extreme weather to theft and sabotage, issues not unfamiliar in countries with complex infrastructure. Eskom’s renewed commitment to operational rigor, technological upgrades, and staff training provides a framework for addressing these risks. Instead of reacting to crisis after crisis, the utility now focuses on building resilience and anticipating problems before they grow.
