South Africa’s electricity crisis has entered a new phase. Eskom revealed that most of the country’s load reduction cases are concentrated in only four provinces, and Gauteng tops the list.
The power utility’s latest briefing to Parliament’s Portfolio Committee on Electricity and Energy exposed how infrastructure failures, theft, and overloading are placing the national grid under serious strain. These problems have turned localised blackouts into an everyday occurrence for many South Africans.

Gauteng Tops the List
Eskom’s data shows that Gauteng accounts for 38% of all load reduction cases, followed by Limpopo with 21%, Mpumalanga with 20%, and KwaZulu-Natal with 18%. The remaining provinces – the Western Cape, Free State, and North West- collectively make up less than 3%.
In simple terms, almost nine out of ten load reduction incidents happen in these four provinces, and Gauteng bears the biggest load.
Unlike load shedding, which is implemented nationally to balance electricity generation and demand, load reduction is a local intervention used to protect infrastructure. It’s applied in areas where illegal connections, overuse, and vandalism threaten to destroy transformers and substations.
Why Gauteng Is the Epicentre
Gauteng’s position as the country’s economic hub comes with challenges. The province’s dense population, sprawling informal settlements, and rapid urban expansion have outpaced infrastructure upgrades. Transformers designed for a few hundred households now serve thousands.
When transformers are overloaded, they overheat or fail. In some cases, they even catch fire, leaving communities without power for weeks. Load reduction, therefore, acts as a defensive measure to prevent equipment damage and widespread outages.
Electricity theft, illegal bypasses, and tampering remain widespread. In several townships, residents share power lines connected through unsafe and unregulated means. This has made Gauteng’s electrical grid one of the most fragile in the country.
The National Picture
The crisis stretches beyond Gauteng. Over the past year, 771 transformers failed across South Africa, prompting Eskom to implement load reduction across 971 network feeders. This has affected about 1.6 million customers.
Of those affected, 90% use prepaid electricity, mostly in low-income and high-density communities. While critics argue that the system unfairly affects poorer households, Eskom maintains that it reflects where infrastructure is most vulnerable.
The Cost of Doing Nothing
Eskom warned that failing to address these infrastructure challenges could cost the country over R600 billion in the next 20 years. The utility already loses 14.7 terawatt hours of electricity annually to theft and illegal connections, an increase from 13.5 terawatt hours the previous year.
That translates to about R30 billion in lost revenue each year, not counting the cost of replacing burnt transformers and repairing vandalised lines. Left unchecked, these losses could severely undermine Eskom’s recovery plan and slow South Africa’s broader economic growth.
Smart Meters and a Modern Grid
To turn the tide, Eskom has launched a nationwide smart meter rollout. This initiative forms the backbone of its plan to modernise the grid and phase out load reduction by March 2027.
Over the next five years, 6.2 million smart meters will be installed across South Africa as part of a R5.7 billion digital transformation project. These devices will allow real-time tracking of electricity usage, early detection of tampering, and faster response to system overloads.
The system will also enable Eskom to limit power consumption remotely during peak periods, instead of completely cutting supply. Once fully operational, the new grid could reduce energy losses by at least 5% annually and help recover billions in revenue.
A Three-Phase Plan to Eliminate Load Reduction
Eskom’s roadmap to end load reduction by 2027 includes three key milestones:
- By March 2026: Address 577,000 of the 1.69 million affected customers.
- By September 2026: Reach an additional 560,000 customers, bringing the total to more than 1.1 million.
- By March 2027: End load reduction for all remaining areas.
This phased approach will be implemented feeder by feeder, with priority given to the hardest-hit regions. Limpopo, for instance, is expected to see its share of load reduction drop from 21% to 13% by March 2026, and reach zero by March 2027.
In KwaZulu-Natal, pilot projects in districts such as Mtubatuba are already underway to test the rollout’s effectiveness.
Load Reduction vs. Load Shedding
Although both cause power cuts, load reduction and load shedding serve different purposes. Load shedding is a national balancing act, used when generation cannot meet demand. Load reduction, by contrast, is a local protective measure that prevents transformer burnout in overburdened areas.
Eskom’s September 2025 data shows that the utility had 28,000 gigawatt hours of available capacity, while national demand was only 20,000 gigawatt hours. This confirms that localised blackouts are not caused by a shortage of power but by grid overloading in specific communities.
Understanding this difference helps explain why one neighbourhood may experience hours of darkness while another nearby remains unaffected.
Why It Matters for Gauteng and South Africa
Gauteng’s dominance in the load reduction statistics reveals long-standing gaps in infrastructure and urban planning. Illegal connections, outdated transformers, and unchecked settlement growth continue to stretch the grid beyond its limit.
Yet this challenge also presents an opportunity to rethink how energy is distributed, secured, and maintained. For municipalities, it means aligning service delivery goals with Eskom’s maintenance plans. For communities, it means safeguarding infrastructure by reporting theft and tampering.
Building a Resilient Power Future
Eskom’s plan offers a way forward, but lasting progress depends on collective responsibility. Investment in smarter systems, better maintenance, and active citizen participation can help restore reliability to the grid.
For Gauteng, this could mark the beginning of a new chapter, one where transformers last longer, outages become rare, and homes and businesses can rely on consistent electricity.
The province may lead in load reduction challenges today, but with awareness, cooperation, and accountability, it can also lead in solutions.
