A Year After Load Shedding, South Africa Fights Electricity Theft

Why It Matters

The transition from scheduled load‑shedding to criminal‑driven outages threatens grid reliability and Eskom’s profitability, accelerating the shift toward decentralized renewable power.

Key Takeaways

• Eskom reports 8% non‑technical losses, costing about $1.1 billion.
• 91,934 unplanned outages occurred last year, average 12‑hour duration.
• Gauteng experiences longest blackouts, averaging 14 hours per incident.
• Electricity tariffs rose 8.76% in April 2026, fueling cost pressures.
• Solar‑battery demand doubled as businesses seek resilience against theft‑driven cuts.

Pulse Analysis

South Africa’s power landscape has fundamentally changed. After a year without load‑shedding, Eskom boasts near‑full‑capacity operation, driven by better coal‑plant performance and expanding wind‑solar capacity. The utility’s latest figures show a 98.9% supply reliability, a dramatic turnaround from the 205‑day load‑shedding crisis of 2022. However, the stability at the national level masks a growing crisis at the distribution tier: illegal hookups and theft of cables and substations now represent 8% of total supply loss, translating into roughly $1.1 billion of lost revenue. This "non‑technical loss" not only drains Eskom’s finances but also creates safety hazards, as illustrated by the fatal accident in Crown Mines.

Unplanned outages have become the new norm. Wetility’s monitoring recorded 91,934 grid interruptions last year, averaging 12.1 hours per event, with only 23.6% restored within two hours. Gauteng, the industrial hub, suffers the longest disruptions—about 14 hours per cut—while the Eastern Cape sees shorter, 6.6‑hour outages. These unpredictable blackouts cripple businesses that can no longer schedule production, staff, or critical services around a known load‑shedding timetable. The financial strain is compounded by an 8.76% tariff increase in April 2026 and a $0.77 rise in diesel wholesale prices, pushing operating costs higher for manufacturers and service providers alike.

The confluence of unreliable supply and rising costs is fueling a rapid uptake of decentralized energy. Solar‑plus‑storage installations have more than doubled year‑over‑year, with rooftop capacity soaring 349% in 2023. Companies are investing in battery‑backed microgrids to safeguard operations against both theft‑induced outages and volatile diesel generator prices, which have spiked due to geopolitical tensions affecting fuel logistics. This shift not only offers resilience but also aligns with South Africa’s broader energy transition goals, positioning renewable technologies as a critical buffer against the lingering shadow of electricity theft.
