Eskom continues to strengthen the resilience of South Africa’s power system, sustaining measurable improvements in generation performance and network stability as winter demand intensifies. Year-on-year gains in generation availability, reduced unplanned outages, and lower reliance on diesel, alongside targeted interventions through the Load Reduction Elimination Programme, are enabling more households to access a stable and consistent electricity supply
System performance continues to strengthen, with the financial year-to-date Energy Availability Factor (EAF) rising to 63.24%, up marginally from 63.05% in the previous week, and significantly higher than 57.91% recorded over the same period last year—an increase of 5.33% year-on-year. This reflects sustained progress under Eskom’s turnaround strategy and a 9.5% improvement (4.8GW) compared to the corresponding period three years ago. These gains are driven by a continued reduction in unplanned outages and more consistent, reliable performance across the generation fleet.
Eskom’s load reduction elimination programme remains on track across all provinces, with about 726 324 households—approximately 43% of affected customers, already restored to normal supply. Full elimination is targeted in seven provinces by October 2026, with the remaining provinces, Gauteng and KwaZulu-Natal, expected to follow in 2027 as targeted interventions continue to address localised network constraints and overloading pressures.
Between 5 and 11 June 2026, average unplanned outages declined to 10 143MW, a significant reduction of 4 304MW from the 14 447MW recorded over the same period last year, almost equivalent to the capacity of Kusile Power Station. This improvement is also reflected in the Unplanned Capacity Loss Factor (UCLF), which improved to 21.18% from 29.61% in the corresponding period last year, representing a significant reduction of 8.43%.
During the same period, Eskom’s Planned Capacity Loss Factor (PCLF), which reflects planned maintenance, averaged 13.01%, higher than the 9.52% in the previous financial year and is aligned with Eskom’s efforts to ensure environmental compliance, improve reliability and support long-term sustainability.
In addition, 1 240MW is currently in cold reserve due to excess capacity.
For the financial year to date (1 April to 11 June 2026), diesel expenditure stands at R615.58 million at a load factor of 1.36%, significantly lower than the R4.112 billion incurred over the same period last year at a load factor of 11.96%, an 88.67% year-on-year reduction.
Diesel in the past week was strategically deployed at peak demand times to meet the higher-than-expected demand as well as provide the required reserves in line with the South African Grid Code.
This continued reduction demonstrates both the cost savings and the operational improvements achieved through Eskom’s ongoing turnaround efforts. Overall, this positive trend highlights the growing stability and efficiency of the power system.
Since 16 May 2025, South Africa has recorded 392 consecutive days without interruptions to electricity supply, reflecting 100% system availability in meeting electricity demand.
During the previous financial year, supply interruptions were limited to 26 hours across four days in April and May 2025, underscoring the improved strength and reliability of the power system.
To further ensure a stable electricity supply, Eskom will bring 2 462MW of generation capacity online ahead of the evening peak on Monday, 15 June 2026. Today’s evening peak demand is forecast at 26 325MW, with 30 138MW of available capacity.
Eskom published the Winter Outlook on 22 April 2026, covering the period 1 April to 31 August 2026, which projects no loadshedding due to sustained improvements in plant performance from the Generation Recovery Plan.
Key Performance Highlights
- For the financial year to date (1 April to 11 June 2026), UCLF has reduced to 22.45%, which is 6.60% lower than the same period in the previous year.
- For the financial year to date (1 April to 11 June 2026), planned maintenance was at an average of 6 664MW, accounting for 14.1% of total generation capacity, higher than the 12.5% (5 875MW) over the same period in the previous year.
- Year-to-date (1 April to 11 June 2026), OCGT generation declined year-on-year to 79.295GWh at a diesel cost of R615.58 million, down approximately 88.67% in output and 85.03% in costs compared to the corresponding period last year.
- The financial year‑to‑date OCGT load factor stands at 1.36%, lower than the 11.96% recorded over the same period last year and well below the target annual load factor of 3%. This level is approximately half of the FY2026 target, reflecting increased confidence in improved fleet performance and reduced reliance on diesel‑fired generation.
Progress in ending load reduction: About 726 324 customers across South Africa are no longer impacted, representing about 43% of targeted households, with full elimination achieved in the Northern and Western Cape.
Although the power system remains stable and generation capacity continues to exceed demand, illegal connections and meter tampering persist in certain localised areas, driving infrastructure damage and posing serious safety risks. Eskom continues to implement load reduction as a temporary, targeted measure in high-risk areas to protect both communities and the electricity network.
To address these challenges sustainably, Eskom has launched a phased programme to eliminate load reduction by 2027. The programme targets 971 feeders and will benefit approximately 1.69 million customers across all provinces, out of Eskom’s total customer base of 7.2 million. Key interventions include the rollout of smart meters, the integration of Distributed Energy Resources, and the expansion of Free Basic Electricity (FBE) support. These measures will be accompanied by targeted customer education initiatives.
Progress on key interventions
- Smart Meter Rollout:
Since inception, Eskom has deployed 1 764 643 smart meters nationwide, reflecting a significant scaling up of installations across the country. Of these, 375 563 meters have been installed on load reduction feeders, representing approximately 21% of deployments in high-priority areas. This targeted rollout is helping to ease grid pressure while enabling customers to access real-time consumption data and exercise greater control over their energy usage.
Of the 375 563 smart meters installed on load reduction feeders, approximately 94% are concentrated in Gauteng, Mpumalanga, Limpopo and KwaZulu‑Natal, where network risk is highest.
The rollout is deliberately focused on high-loss areas affected by illegal connections, meter bypassing, overloaded infrastructure and widespread electricity theft. Eskom has undertaken extensive community and stakeholder engagement through ward councillors, public meetings, radio platforms and social media to support the implementation of the programme.
Despite these efforts, installation teams continue to face persistent resistance, including intimidation, violent incidents and repeated work stoppages. These disruptions have led to deployment delays, the redeployment of teams, and heightened safety risks for Eskom employees and contractors.
As a result, over 122 000 planned meter conversions have been delayed to date, undermining the stability and predictability of the rollout programme.
Eskom is calling on all affected communities to partner with its teams to help accelerate the elimination of load reduction, in line with planned timelines or sooner where possible.
- Feeders removed from Load Reduction:
A total of 447 feeders have been removed from load reduction, against a planned target of 971, reflecting approximately 46% progress. This includes:
- 72 feeders in Limpopo and Mpumalanga (48% of the target of 150).
- 236 feeders in Gauteng (39% of the target of 604).
- 10 feeders in the Eastern and Western Cape (66.7% of the target of 15). Notably, the Western Cape achieved 100% of its target, resulting in the complete elimination of load reduction in the province.
- 117 feeders in the Free State and KwaZulu-Natal (60.6% of the target of 193).
- 12 feeders in the North West and Northern Cape (133.3% of the targeted 9). Notably, the Northern Cape achieved 100% of its target, resulting in the complete elimination of load reduction in the province.
- Customers benefiting from the elimination of the load reduction programme:
To date, the removal of feeders from load reduction has enabled an estimated 726 324 customers to benefit, representing about 43% of the 1.69 million customers targeted for the programme. This includes 256 703 customers in Limpopo and Mpumalanga; 268 902 in Gauteng; 12 422 in the Eastern and Western Cape; 150 340 in KwaZulu‑Natal and the Free State; and 37 957 in the North West and Northern Cape.
- Free Basic Electricity (FBE):
Nationally, registrations are at 577 061 customers. The FBE beneficiaries figure fluctuates monthly. The 577 061 figure reflects a 19% increase from the baseline of 485 000 customers and represents about 27% of the 2.1 million eligible customers.
