Eskom passed more than 400 consecutive days without load shedding in mid-July 2026, with the utility’s own performance data showing sustained improvement in plant reliability. But the same utility’s medium-term outlook contains a more cautious message: without changes to the current power station decommissioning schedule, load shedding could return within three to four years.
How Eskom’s performance has actually improved
Eskom’s Energy Availability Factor (EAF) — a measure of how much of its total generation capacity is actually available to produce electricity at any given time — rose to 64.29% for the financial year to date (1 April to 2 July 2026), up from 58.54% over the same period the previous year. Unplanned outages, a key driver of past load shedding, also declined: for the week of 19–25 June 2026, unplanned capacity losses averaged 11,259MW, down from 14,801MW in the same week the previous year, and the Unplanned Capacity Loss Factor improved to 23.63% from 30.86%.
These are genuine operational improvements, not merely a lucky run of stable weeks — sustained gains in EAF and reduced unplanned outages reflect changes in how Eskom’s power stations are being maintained and run.
Why load shedding stopped, in plain terms
Load shedding happens when Eskom’s available generation capacity can’t meet electricity demand, forcing scheduled outages to protect the grid from an uncontrolled collapse. Improved plant maintenance and reduced unplanned breakdowns mean more of Eskom’s existing capacity has been reliably available, reducing the gap between supply and demand that previously required load shedding to manage.
The caveat Eskom itself has flagged
Eskom’s own Medium-Term System Adequacy Outlook, covering 2026 to 2030, reportedly warns that load shedding could return within three to four years if the current schedule for decommissioning ageing coal-fired power stations proceeds without enough new generation capacity coming online to replace it. This is a significant caveat from the utility itself, not an outside critic — it suggests the current stability reflects better management of existing capacity rather than a structural expansion of that capacity. Our opinion piece, whether Eskom has really fixed the crisis or just delayed it, examines this tension in more depth.
The group still facing outages: load reduction
Separate from national load shedding, Eskom’s Load Reduction Eradication Programme addresses a different problem: scheduled outages in overloaded township and lower-income electricity networks, distinct from the load shedding applied nationally when generation capacity is short. That programme has reportedly reached 65% of its target, with around 1.1 million customers removed from load reduction schedules, fully eliminated in five provinces, and on track for seven provinces by October 2026 and nationally by 2027. This matters because the “no load shedding” milestone, while real, doesn’t reflect the full picture for households still affected by load reduction in their specific network.
What this means for households and businesses
- Sustained grid stability has reduced reliance on backup power sources like generators and battery inverter systems for many households and businesses, lowering associated running costs.
- Electricity tariff increases approved to help fund Eskom’s operational turnaround have contributed to rising household costs even as reliability has improved — see our report on May 2026’s inflation data, which shows housing and utilities costs as a meaningful driver of recent inflation.
- Households in areas still affected by load reduction (as distinct from load shedding) may not experience the same improvement reflected in national headlines.
What happens next
Eskom’s Winter Outlook, published in April 2026, projected no load shedding through 31 August 2026. Beyond that window, the utility’s own multi-year outlook is the more important document to watch, since it explicitly ties continued stability to decisions about power station decommissioning and new generation capacity that are still being finalised.
What “new generation capacity” actually requires
Closing the gap Eskom’s own outlook identifies isn’t simply a matter of announcing new projects — new generation capacity, whether coal, gas, nuclear or renewable, requires years of planning, environmental approval, construction and grid connection work before it can contribute meaningfully to supply. This lead time is part of why energy analysts stress that decisions made today about new capacity have consequences three, five or more years into the future, rather than offering any immediate fix to a looming shortfall. It also means that if Eskom’s three-to-four-year risk window is accurate, decisions about new capacity needed to avoid that risk would need to be well underway now, not merely under consideration.
The role of private and renewable generation
Regulatory reforms over recent years have opened South Africa’s electricity market to significantly greater private-sector generation, including large-scale renewable energy and battery storage projects developed independently of Eskom and sold either directly to large users or into the broader grid. This shift, part of the government’s Operation Vulindlela reform programme, is intended to diversify where new generation capacity comes from, rather than relying solely on Eskom’s own build programme. Whether private and renewable capacity comes online fast enough to meaningfully offset the retirement of Eskom’s ageing coal fleet remains one of the central open questions in South Africa’s energy outlook.
What businesses have done differently during the stable period
Many South African businesses invested heavily in backup power infrastructure — generators, solar systems, battery storage — during the peak years of load shedding, and the sustained stability since then has allowed some to reduce reliance on that backup infrastructure, lowering operating costs. Others have kept backup systems in place as insurance, judging the three-to-four-year risk window flagged in Eskom’s own outlook as reason enough not to fully stand down contingency planning built up over the preceding, harder years.
Why maintenance culture matters as much as capacity
Eskom’s improved performance has been attributed substantially to changes in maintenance philosophy — shifting toward more planned, preventative maintenance rather than reactive repairs after equipment has already failed. This kind of operational discipline, while less visible to the public than a headline capacity number, is often what determines whether existing power stations can be kept running reliably for longer, extending the effective lifespan of the current fleet and buying additional time for new capacity to come online.
Why “days without load shedding” became such a widely tracked figure
The consecutive-days counter has become a widely referenced shorthand for Eskom’s turnaround largely because it is simple, easily understood, and directly tied to something ordinary South Africans experienced acutely for years. Its simplicity is also its limitation, as this article has argued — a single number cannot capture the more nuanced underlying picture of maintained-but-ageing capacity, tariff trade-offs and medium-term risk that a fuller assessment of Eskom’s position requires.
Frequently asked questions
Is load shedding over for good in South Africa?
Eskom has not made that claim. Its own medium-term outlook warns load shedding could return within three to four years without changes to the current decommissioning schedule, even as short-term performance has improved substantially.
What is load reduction, and is it different from load shedding?
Yes — load reduction refers to scheduled outages targeted at specific overloaded township or lower-income networks, distinct from load shedding, which is applied nationally when total generation capacity falls short of demand.
