Eskom’s 490 days without load shedding hinge on fragile gains in South Africa’s power grid
South Africa’s Eskom says it has avoided load shedding for 490 days and lifted its energy availability factor to nearly 68%, the best level in six years, while saving more than $295 million in diesel costs.
South Africa’s state‑owned power utility says it has reached 490 days without scheduled blackouts, a striking turnaround in a country where rolling power cuts had become routine.
Eskom announced that since the start of its current financial year it has achieved an energy availability factor, or EAF, of nearly 68%. That’s the highest figure in six years, according to the company. In mid‑September, the weekly EAF reached 72.74%, helping the utility cut its use of expensive diesel‑fired generation.
The improvement has had a direct financial payoff. Eskom says the stronger performance reduced diesel expenditure by more than $295 million. Diesel plants are meant to cover peaks and emergencies, not serve as everyday workhorses, so burning less fuel eases pressure on both the utility’s balance sheet and the wider economy.
For households and businesses, the absence of load shedding has meant more predictable days and fewer forced workarounds. It’s also feeding a sense that a system long associated with crisis might be stabilizing. At the same time, the headline EAF numbers point to a grid that’s still under strain, not one that has fully recovered from years of breakdowns and postponed maintenance.
Eskom’s coal‑heavy fleet remains old and vulnerable to sudden outages, and the current performance rests on keeping enough of that capacity online at once. Sustaining an EAF near current levels through periods of peak demand will be a key test of whether the utility has turned a corner or is benefiting from a temporary run of better availability.
The diesel savings buy Eskom some breathing space to manage debt and fund repairs, but they don’t by themselves solve deeper structural issues such as aging plants and the need for new generation. How the utility uses this window—on maintenance, investment and planning—will determine whether South Africans can count on another year without scheduled blackouts.
Signals to watch include whether the EAF holds up as demand fluctuates, any change in the frequency or severity of unplanned outages, and concrete announcements on new capacity or grid upgrades. Those moves will show if the current reprieve from load shedding is becoming the new normal or remains a fragile exception.
