Johannesburg, South Africa – Eskom, the nation’s power utility, announced a important breakthrough on Friday, reporting that unplanned power outages have plummeted too their lowest levels in almost five years. Currently, only 7,265MW of generating capacity is offline due to breakdowns, a marked advancement in the nation’s electricity supply.
A Turning Point for South Africa’s Energy Crisis
This milestone represents the first instance as December 11, 2020, where total unit breakdowns have fallen below the 8,000MW threshold.officials attribute this success to sustained enhancements in plant performance, driven by the ongoing implementation of the Generation Recovery Plan.
According to Eskom representatives, technical improvements have ensured a robust power system, consistently fulfilling over 97% of electricity demand throughout the current winter season and financial year to date. The outlook remains positive, with the system poised to maintain stability and reliably meet anticipated demand in the coming week.
Key Performance Indicators Show Improvement
Since the commencement of Eskom’s financial year on April 1st, to August 21st, 2025, the Unplanned Capability Loss Factor has decreased to 27.85%. While still approximately 2.0% higher than the 25.81% recorded during the same period last year, this marks a week-on-week improvement of approximately 0.29%.
Average weekly unplanned outages have also decreased, registering at 10,471MW, down from the 10,733MW recorded during the equivalent period in the previous year. Simultaneously, Eskom has slightly increased planned maintenance, with an average of 5,524MW offline for scheduled work.
Year-to-date, planned maintenance averages 5,223MW, accounting for 11.12% of the total generation capacity, a 0.8% increase from the previous year. The Energy availability Factor (EAF) has fluctuated between 63% and 69%, with the month-to-date average reaching 64.98%.
| metric | Current (Aug 21, 2025) | Same Period Last Year |
|---|---|---|
| Unplanned Capability Loss Factor | 27.85% | 25.81% |
| Average unplanned Outages | 10,471MW | 10,733MW |
| Planned Maintenance | 5,223MW (11.12%) | 5,000MW (10.32%) |
| Energy Availability Factor (EAF) | 64.98% | 63.35% |
Kusile Unit 6, contributing 720MW to the national grid as March 23, 2025, is excluded from these figures. The unit is projected to achieve commercial operation by September 2025.
Diesel Consumption and Financial Implications
As of Friday evening, available generation capacity stood at 30,442MW, while electricity demand was predicted to reach 25,378MW, signifying sufficient capacity to meet current and anticipated needs. Eskom has not implemented load-shedding since May 15, 2025, with only 26 hours of rotational power cuts recorded since the start of the financial year.
Despite overall improvements, the year-to-date EAF stands at 60.56%, slightly lower than the 63.35% recorded during the same period last year,primarily due to a 2% increase in unplanned maintenance. The utility also reduced its reliance on diesel-powered open-cycle gas turbines (OCGT), decreasing the load factor from 1.21% to 0.78% over the last week.
However, year-to-date OCGT usage remains higher than last year, at 8.53% compared to 4.48%. Eskom has spent R5.916 billion on fuel for OCGT plants between April 1st and August 21st,2025,generating 999.95GWh of electricity, a significant increase from the 525.44GWh generated during the same timeframe last year. Eskom maintains that this spending remains within budget and adjusts seasonally based on demand.
the power utility intends to restore 4,850MW of generation capacity before Monday’s evening peak and throughout the coming week. The Winter Outlook remains valid, indicating that load-shedding will not be necessary if unplanned outages remain below 13,000MW.
Understanding Eskom and South Africa’s Energy Challenges
Eskom is a state-owned enterprise responsible for generating, transmitting, and distributing approximately 95% of South Africa’s electricity.For years, the country has struggled with an unreliable power supply due to aging infrastructure, insufficient investment, and increasing demand. The Generation Recovery Plan represents a critical effort to address these systemic issues and ensure energy security for the nation.
Did You Know? South Africa is investing heavily in renewable energy sources, such as solar and wind power, to diversify its energy mix and reduce its reliance on coal.
