Friday, 02 October 2026: Eskom maintains its strongest operational performance in six years, with the year-to-date Energy Availability Factor (EAF) reaching 68.11%, reinforcing progress in restoring energy security and supporting economic growth. Supported by lower unplanned outages, improved generation fleet reliability and an 80.49% year-on-year reduction in diesel expenditure, South Africa has now achieved more than 500 consecutive days without loadshedding.
During the past week, electricity demand from the grid increased by approximately 1 000MW due to overcast weather conditions reducing rooftop solar output, highlighting the complementary role that Eskom’s generation fleet and customer-owned solar installations play in meeting the country’s electricity needs.
Eskom’s operational improvement continues to deliver measurable results, with unplanned outages improving by 6.69% year-on-year and approximately 2 943MW of generation capacity returned to service.
The organisation also exceeded its particulate emissions target, achieving particulate emissions levels of 0.32kg/MWhSO, better than the target of 0.35kg/MWhSO. Sustained emissions performance below target levels for more than a year since October 2025 reflects ongoing progress in strengthening generation reliability and environmental performance.
Compared with three years ago, Eskom has improved its Energy Availability Factor (EAF) by 12.76 percentage points and returned approximately 6 492MW of generation capacity to the grid, demonstrating sustained progress in enhancing generation reliability and strengthening South Africa’s energy security.
From 1 April to 1 October 2026, diesel expenditure declined by R4.79 billion, or 80.49%, compared to the same period last year, decreasing from R5.95 billion to R1.16 billion. Over the same period, the Open Cycle Gas Turbines (OCGT) load factor reduced sharply from 6.72% to 1.02%, reflecting the impact of improved plant performance and the contribution of additional generation capacity to the grid.
Combined, these results demonstrate Eskom’s continued progress in delivering a more reliable, cost-efficient and environmentally sustainable electricity supply for South Africa.
Alongside its operational recovery, Eskom continues to make substantial progress in its commitment to eliminate load reduction by March 2027 through the Load Reduction Eradication Programme. Seven provinces remain free from load reduction, with approximately 1.5 million customers restored to normal supply conditions. The number of customers affected by load reduction has declined from 1.69 million to 202 590, representing just 2.8% of Eskom’s customer base. While the remaining affected customers are in Gauteng and KwaZulu-Natal, more than 60% of previously affected customers in these two provinces have already been restored to normal supply conditions, with eradication efforts continuing in the remaining areas.
South Africa has now recorded 504 consecutive days without loadshedding since 16 May 2025, reflecting the cumulative impact of improved fleet performance, lower unplanned outages, increased generation capacity and reduced reliance on emergency generation resources. This milestone demonstrates the sustained progress being made in restoring reliability, strengthening energy security and supporting South Africa’s economic growth and development.

Eskom continues to maintain additional system capacity, with 6 722MW in cold reserve due to excess capacity, providing further assurance of system adequacy.
Today’s evening peak is forecast at 23 382MW, against available capacity of 26 036MW excluding gas. We expect 3 900MW to come back online ahead of the evening peak on Monday, 5 October 2026.
The power system status and Summer Outlook will be announced in the coming weeks.
Progress in Ending Load Reduction
Seven provinces remain load reduction-free as 88% of targeted customers return to normal supply and load reduction impact falls to just 202 590 customers.
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 (DER), 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:
To date, 517 872 smart meters have been installed on load reduction feeders, reaching approximately 90% of the 577 347 target for high-priority areas. Approximately 83% of these installations are concentrated in Gauteng, Mpumalanga, Limpopo and KwaZulu-Natal, where network pressure is highest. The rollout remains focused on high-loss areas impacted by illegal connections, infrastructure overloading and electricity theft.
Despite ongoing stakeholder engagement, including work with ward councillors, public meetings and media platforms, resistance in some areas continues to affect progress. These include safety incidents, intimidation and work stoppages, resulting in delays, with more than 122 000 planned installations impacted to date.
Feeders removed from load reduction:
Seven of South Africa’s nine provinces have been completely removed from load reduction.
A total of 593 feeders have been removed from load reduction, representing approximately 61% of the 971 target.
- 163 feeders in Limpopo and Mpumalanga (exceeding the target of 150), with both provinces achieving full elimination.
- 251 feeders in Gauteng (41.5% of the target of 604).
- 14 feeders in the Eastern and Western Cape (100% of the target), with both provinces achieving full elimination.
- 150 feeders in the Free State and KwaZulu-Natal (77.7% of the target of 193), with the Free State achieving full elimination.
- 15 feeders in the North West and Northern Cape (exceeding the target of 9), with both provinces achieving full elimination.
Customers benefiting:
An estimated 1 487 410 customers are no longer impacted by load reduction, representing approximately 88% of the 1.69 million customers targeted under the programme. This includes 670 785 customers in Limpopo and Mpumalanga; 493 243 in Gauteng; 29 812 in the Eastern and Western Cape; 243 342 in KwaZulu-Natal and the Free State; and 50 228 in the North West and Northern Cape.
Free Basic Electricity (FBE):
A total of 546 576 customers are registered for FBE, reflecting approximately a 13% increase from the baseline of 485 000 customers. This represents approximately 26% of the 2.1 million eligible customers.
Eskom continues to strengthen the network through targeted interventions, technology deployment and community engagement.
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.
