i Short answer
South Africa achieved a genuinely sustained turnaround, going over 365 consecutive days without load shedding by mid-May 2026, the longest such stretch since September 2018. Eskom's Energy Availability Factor improved from around 55% to over 65%, and S&P Global Ratings upgraded Eskom's own credit rating for the first time in over a decade.
For traders, this removes a long-standing, well-known drag on South African growth and investor sentiment, indirectly supportive of the Rand and JSE over time, though electricity tariffs are still rising and the improvement isn't guaranteed to be permanent.

South Africa's Power Turnaround: 2026 Numbers
This reflects the situation as of mid-2026, verify current load shedding status directly with Eskom or EskomSePush.
1. The scale of the turnaround
On 16 May 2026, Eskom marked 365 consecutive days without a single second of load shedding, a milestone not achieved since September 2018. This represents a dramatic reversal from the depths of the crisis in 2023, when the country experienced 335 days of load shedding and 16.6 million MWh shed in a single year.
Eskom's Energy Availability Factor, a core measure of how much of its generation fleet is actually available to produce power, improved from roughly 55% in FY2023 to over 65% in FY2026, with unplanned outages falling from over 16.5GW to approximately 9.4GW over the same period. The utility has stated it does not expect load shedding through the 2026 winter season.
2. What actually drove the improvement
Several factors combined to produce this turnaround rather than any single fix. Reduced unplanned generation outages and the return to service of previously offline units (including Medupi Power Station's Unit 4) improved baseline reliability. Eskom's Generation Recovery Plan added approximately 4,000MW of extra capacity to meet demand.
| Factor | Impact |
|---|---|
| Reduced unplanned outages | 16.5GW → ~9.4GW |
| Generation Recovery Plan | +4,000MW added capacity |
| Private solar (post licensing cap removal) | +5,000MW in 18 months |
Separately, private solar capacity surged following the removal of licensing caps on embedded generation, with roughly 5,000MW added within 18 months and a further 12,000MW reportedly in the pipeline, meaningfully reducing reliance on Eskom-generated electricity specifically, alongside Eskom's own operational improvements.
3. How this affects the JSE
Reduced load shedding directly benefits sectors most exposed to power disruption costs, manufacturing, retail, and broader industrials, some of which feature among the most actively traded JSE shares, through lower operating costs (meaningfully reduced diesel generator reliance) and more predictable, reliable production schedules. Eskom itself saved an estimated R26.9 billion in diesel costs over three years as a direct result of the improved operational reliability.
S&P Global Ratings upgraded Eskom's own credit rating for the first time in over a decade specifically citing this sustained operational improvement and financial discipline, a signal that also supports broader South African sovereign risk sentiment relevant to the JSE more generally, beyond just the directly affected sectors.
4. The indirect effect on the Rand
Load shedding was long cited by international investors and rating agencies as a specific, well-documented drag on South African growth potential and investment appeal. Its sustained absence removes a well-known negative factor from the broader risk assessment applied to South African assets generally, including the Rand.
This isn't a single-event catalyst the way a specific SARB rate decision is, rather, it's a structural improvement in South Africa's broader investment case that supports sentiment gradually over time, worth factoring into your overall read of South African risk appetite rather than treating as a standalone trading trigger.
5. What's not resolved: tariffs and future risk
The electricity situation isn't fully resolved even as reliability has genuinely improved. South Africa's energy regulator NERSA approved an 8.76% tariff increase for direct Eskom customers effective April 2026, with a further 9.01% increase for municipal customers from July 2026, and an additional 8.83% hike already approved for 2027/28. This means electricity costs continue rising meaningfully even as blackouts have become rare.
Longer-term risk also remains, energy experts have specifically warned load shedding could plausibly return around 2030 if Eskom's planned transition, closing roughly 5,260MW of coal power by 2029 in favour of new gas power stations, faces delays, a track record concern given how long Eskom's previous major projects (Medupi and Kusile) took to complete.
6. Fitting this into the broader 2026 picture
The end of sustained load shedding is one meaningful input among several shaping South Africa's 2026 economic narrative, alongside the interest rate environment, inflation trajectory, and broader fiscal position. It represents a genuine, positive structural development rather than a temporary reprieve, given the scale and duration of the improvement documented here.
Worth factoring into your broader read of South African risk sentiment and the local investment case generally, without treating it as a standalone reason to expect any specific near-term market move, structural improvements of this kind tend to influence sentiment gradually rather than through a single, identifiable price reaction.
Key Takeaways
- South Africa went over 365 consecutive days without load shedding by mid-May 2026, its longest stretch since September 2018, and Eskom does not expect load shedding through the 2026 winter.
- The turnaround was driven by reduced unplanned outages, returned generation units, roughly 4,000MW of added capacity, and a major surge in private solar capacity following licensing cap removal.
- S&P Global Ratings upgraded Eskom's credit rating for the first time in over a decade, citing sustained operational improvement, a signal relevant to broader South African risk sentiment.
- Sectors most exposed to load shedding costs, manufacturing, retail, and industrials, benefit directly from lower diesel generator reliance and more predictable production.
- Electricity costs are still rising even as reliability improves, NERSA approved an 8.76% tariff increase effective April 2026, with further increases already approved into 2027/28.
- The improvement isn't guaranteed to be permanent, energy experts have warned load shedding could plausibly return around 2030 if Eskom's coal-to-gas transition plans face delays.
Frequently asked follow-up questions
Has load shedding actually ended permanently in South Africa?
Not permanently in an absolute sense, but South Africa achieved a genuinely sustained turnaround, going over 365 consecutive days without load shedding by mid-May 2026, the longest such stretch since September 2018. Eskom's Energy Availability Factor improved from around 55% in FY2023 to over 65% in FY2026, and the utility has publicly stated it doesn't expect load shedding through the 2026 winter season.
What actually drove this turnaround?
Several factors combined: significantly reduced unplanned generation outages (falling from over 16.5GW to roughly 9.4GW), the return to service of previously offline generation units, an additional roughly 4,000MW of extra capacity from Eskom's Generation Recovery Plan, and a major increase in private solar capacity, around 5,000MW added within 18 months of licensing caps being removed, with more in the pipeline.
How does this affect the JSE specifically?
Reduced load shedding directly benefits sectors that were most exposed to power disruption costs, manufacturing, retail, and industrials generally, by lowering operating costs (less diesel generator reliance) and improving production reliability. S&P Global Ratings upgraded Eskom's own credit rating for the first time in over a decade, citing sustained operational improvement, a signal that also supports broader South African risk sentiment relevant to the JSE.
Does this mean the Rand benefits directly from the end of load shedding?
Indirectly, yes, load shedding was long cited as a specific drag on South African growth and investor confidence, its sustained absence removes a well-known negative factor from the broader risk assessment international investors apply to South African assets, including the Rand. This isn't a single-event catalyst the way a rate decision is, but a structural improvement in the investment case that supports sentiment over time.
Is the electricity situation actually fully resolved, or are there remaining risks?
No, meaningful risks remain. NERSA approved substantial tariff increases, 8.76% for direct Eskom customers effective April 2026, with further increases already approved into 2027/28, meaning electricity costs are still rising even as reliability improves. Energy experts have also warned load shedding could plausibly return around 2030 if Eskom's planned transition from coal to new gas power stations faces delays.
How does this connect to South Africa's broader economic outlook traders should watch?
The end of sustained load shedding is one input among several shaping South Africa's 2026 economic narrative, alongside the interest rate environment, inflation trajectory, and fiscal position. It's a genuinely positive structural development worth factoring into your broader read of South African risk sentiment, without treating it as a standalone reason to expect any specific market move.
