Eskom Reports Stable Electricity Supply Heading into Winter Peak

As South Africa enters the coldest season, Eskom assures a stable electricity supply for the winter peak. Demand rises because households and businesses use more heating and light. Eskom, the main power utility, has worked hard to boost its generation capacity and manage outages. With careful planning and emergency reserves, Eskom aims to avoid load-shedding and meet the country’s needs throughout winter. The utility has significantly reduced unplanned breakdowns, improving overall grid reliability. New capacity additions, such as the recent return of key power units, strengthen the supply during critical peak hours. Eskom also continues to monitor system performance closely and respond quickly to any emerging issues.

Steady Improvements in Power System Reliability

Eskom’s power system shows growing strength due to technical upgrades and better management. Unplanned outages recently dropped to about 11,555 MW in late July 2025. This is well below the critical level that triggers load-shedding. Since May, Eskom has kept breakdowns manageable. These improvements help the grid stay stable as demand grows. The utility’s focus on preventive maintenance and quicker repairs has played a key role in reducing unexpected failures. Additionally, staff training and upgraded monitoring systems have enhanced operational efficiency. These combined efforts contribute to a more reliable power supply during high-demand periods.

Capacity Additions Strengthen Energy Security

Besides cutting outages, Eskom will add nearly 4,000 MW of capacity soon. This will help supply electricity during the evening peak. Medupi Power Station returned Unit 4, adding 800 MW. This is a key step for South Africa’s energy security. Returning capacity ensures Eskom can meet both current and forecasted demand through winter.

Managing Planned Maintenance with Care

Eskom schedules planned maintenance carefully to keep supply steady. Although outages averaged 5,050 MW in late July, this rise supports essential upkeep. The utility balances maintenance with demand to protect the grid’s health and avoid risks. This approach ensures power plants remain reliable over time.

Positive Trends in Energy Availability and Outages

Two key indicators show Eskom’s progress. The Energy Availability Factor (EAF) improved to about 63% in July 2025. This measures available capacity versus installed capacity. At the same time, the Unplanned Capability Loss Factor (UCLF) has slightly declined from last year. The UCLF tracks capacity lost to unexpected outages. These trends show Eskom’s efforts to reduce breakdowns and boost performance.

Strategic Use of Emergency Reserves

Eskom uses emergency reserves during the morning and evening peak hours. This quick response helps handle sudden demand spikes or system issues. “With 37 days remaining in Eskom’s Winter Outlook period, the system remains well-positioned to maintain stability and meet demand effectively,” Eskom said. This strategic reserve use helps avoid load-shedding during winter’s high demand.

Load-Shedding Unnecessary Since Mid-May

Eskom has avoided load-shedding since 15 May 2025, a relief for consumers. Only 26 hours of load-shedding occurred between 1 April and late July. This is much less than earlier expected. Eskom credits this success to better system management and returning capacity. It continues to watch outage levels closely and acts fast if risks rise.

Supporting Economic Stability and Comfort

Stable electricity during winter supports South Africa’s economy and households. Power cuts disrupt businesses, schools, and services. They also cause discomfort for families relying on electric heating. By keeping the grid stable, Eskom supports business continuity and helps millions stay warm and safe.

Challenges Remain but Progress Is Clear

Despite progress, challenges stay. The UCLF remains above 28%, showing room to lower unexpected outages. Repair and maintenance speed still need improvement. However, reduced breakdowns, increased capacity, and no recent load-shedding point to clear gains compared to past years.

Eskom’s Forward-Looking Winter Outlook

Eskom’s Winter Outlook from May 2025 remains positive. It predicts that if unplanned outages stay below 13,000 MW, load-shedding will be avoided until August’s end. Should outages rise but stay under 15,000 MW, limited Stage 2 load-shedding could occur for up to 21 days. Eskom commits to keeping outages low through proactive fixes and bringing more capacity online.

Commitment to Reliable Power Supply

Eskom leaders show confidence. “We are actively returning generation units to service and managing our system constraints well to ensure reliable electricity supply this winter,” an Eskom spokesperson said. Their focus on steady improvement and planning aims to protect South Africa’s energy security and economy during the peak season.

Overall, Eskom’s current performance and capacity additions indicate strong readiness for winter peak demand. Through targeted maintenance, system upgrades, and strategic crisis management, Eskom has improved its ability to keep the lights on for homes and businesses as temperatures fall.
