South Africa has recorded its strongest electricity system performance in almost a decade, according to Eskom, with the power utility reporting zero diesel use for two consecutive weeks, its lowest unplanned outages in eight years and 441 consecutive days without load shedding. The update was released on Monday, 3 August 2026, and reflects Eskom’s operational performance between 24 and 30 July. The improvements matter for households, businesses and industries across Gauteng because a more stable electricity supply reduces pressure on the national grid, lowers operating costs and improves energy security.
Eskom said the latest results demonstrate continued progress under its Generation Recovery Plan, with improved power station reliability reducing the need for expensive emergency generation and allowing available capacity to comfortably meet electricity demand during the winter period.

Eskom Reports Zero Diesel use For a Second Consecutive Week
One of the most significant milestones in Eskom’s latest operational update is the complete elimination of diesel powered emergency generation for two consecutive weeks.
According to the utility, no diesel was used to support the national grid between 24 and 30 July.
The reduction represents a substantial saving compared with the same period last year.
Eskom said year to date diesel expenditure stands at R807.41 million, compared with R5.63 billion over the corresponding period in 2025.
The utility said this reflects an 85.67 percent reduction in diesel costs.
According to Eskom, the lower spending has been made possible by improved generation performance and sufficient electricity generation capacity to meet national demand without relying on diesel-powered open-cycle gas turbines.
Reducing diesel consumption is regarded as a key objective because emergency generation is significantly more expensive than electricity produced by Eskom’s coal fired power stations.
Energy Availability Factor Reaches Highest Level Since 2017
Eskom also reported a major improvement in the availability of its generation fleet.
The utility recorded a daily Energy Availability Factor of 82.04 percent on 26 July, marking the highest level achieved since 2017.
Energy Availability Factor measures the percentage of Eskom’s generating fleet that is available to produce electricity at any given time.
A higher percentage indicates that more power stations are operating reliably, reducing the likelihood of electricity shortages.
According to Eskom, more than 85 percent of its coal fired generating fleet is now operating with Energy Availability Factor levels ranging between 73 percent and 97 percent.
The utility said this represents an improvement of 11.8 percent over the past three years and has restored approximately 5.9 gigawatts of generating capacity to the national electricity system.
Unplanned Outages Fall to Lowest Level in Eight Years
Another key indicator showing improved system performance is the continued decline in unplanned breakdowns at Eskom power stations.
The utility reported that unplanned outages have decreased to 4 562 megawatts, the lowest level recorded in eight years.
Eskom also reported significant improvements in its Unplanned Capacity Loss Factor, which measures the amount of generating capacity unavailable because of unexpected equipment failures.
According to the utility, the Unplanned Capacity Loss Factor improved to 11.74 percent, compared with 22.21 percent during the same period last year.
Lower outage levels provide system operators with greater flexibility to manage electricity demand without resorting to rotational power cuts.
South Africa Reaches 441 Consecutive Days Without Load Shedding
Eskom confirmed that South Africa has now gone 441 consecutive days without load shedding since May 2025.
The utility said electricity demand was successfully met every day between April and July 2026, with available generation capacity exceeding expected winter demand.
The achievement represents one of the country’s longest sustained periods without rotational power cuts since load shedding became a recurring feature of South Africa’s electricity system.
According to Eskom, improved maintenance planning, stronger generating performance and lower unplanned outages have all contributed to the improved reliability of the national grid.
Load Reduction Programme Continues To Expand
While load shedding has remained suspended nationally, Eskom continues to implement its Load Reduction Eradication Programme in areas where local electricity infrastructure has historically experienced overloading and illegal connections.
The utility said six provinces are now free from scheduled load reduction.
According to Eskom, approximately 1.196 million customers have been removed from load reduction schedules through targeted network upgrades and infrastructure improvements.
Officials said Eskom aims to eliminate load reduction in a seventh province before October 2026, with nationwide eradication targeted for 2027.
Why Reliable Electricity Matters for Gauteng
Gauteng remains South Africa’s economic hub, with industries, businesses, hospitals, schools and transport systems relying heavily on a stable electricity supply.
Improved power availability helps reduce operational disruptions for manufacturers, retailers and service providers while supporting economic activity across Johannesburg, Tshwane and Ekurhuleni.
Reliable electricity also benefits households by reducing interruptions to daily life, improving business confidence and lowering dependence on backup generators and alternative power sources.
Although Eskom’s latest figures indicate substantial operational improvements, the utility has said it will continue investing in maintenance to sustain long term reliability across its generating fleet.
What This Means for Gauteng Residents
For residents and businesses across Gauteng, Eskom’s latest performance update could translate into greater confidence in the reliability of the electricity supply.
If current performance levels continue, Gauteng residents may benefit from:
- Continued suspension of load shedding
- Improved electricity reliability for homes and businesses
- Reduced dependence on costly diesel powered emergency generation
- Better conditions for business operations and economic activity
- Greater stability during periods of high electricity demand
The improvements also support critical services including healthcare facilities, schools, public transport systems and industrial operations that depend on uninterrupted electricity.
FAQ
How many days has South Africa gone without load shedding?
According to Eskom, South Africa has now recorded 441 consecutive days without load shedding since May 2025.
Why is zero diesel use significant?
Diesel powered generators are used during electricity shortages and are expensive to operate. Eliminating diesel use reduces operating costs and indicates that enough electricity is being generated from the existing power station fleet.
What is the Energy Availability Factor?
The Energy Availability Factor measures how much of Eskom’s electricity generation fleet is available to produce power. Higher availability generally improves the stability of the national grid.
Has load reduction also improved?
Yes. Eskom said six provinces are now free from load reduction schedules, with approximately 1.196 million customers removed from the programme through network improvements.
Does this mean load shedding will never return?
No. Eskom’s latest update reflects current system performance. The utility said it continues to focus on maintenance and operational improvements to sustain electricity reliability.
Looking Ahead
Eskom’s latest operational update reflects its strongest electricity generation performance in nearly a decade, with record improvements in generation availability, lower unplanned outages and significantly reduced diesel spending. The utility says these gains have helped South Africa maintain 441 consecutive days without load shedding while improving energy security. For Gauteng residents and businesses, the latest figures indicate a more stable electricity system, although Eskom says ongoing maintenance and infrastructure improvements remain essential to sustaining these performance levels.
