Why is electricity expensive in South Africa? Households are feeling the pinch: recent tariff hikes of up to 12.7% pushed average residential prices above the global average—about $0.19 per kWh.
Consumers see it in every utility bill, courting frustration and financial pressure. But the reasons reach far deeper than meter readings.
Aging Infrastructure and High Maintenance Costs
Eskom’s coal-fired fleet is old. Fifteen power stations built between 1961 and 1996 now require expensive repairs. Projects like Medupi and Kusile spiraled in cost—doubling to over R230 billion due to delays, technical errors, and corruption. That cost is embedded in tariffs.
Rising Debt and Municipal Arrears
Eskom carries over R400 billion in debt. Municipalities owe around R95 billion and counting. That shortfall forces Eskom to borrow more—adding interest to operating costs. Ratepayers end up subsidizing mismanagement through higher tariffs.
Fuel, Supply and Demand Pressures
Coal prices have surged, partly due to global logistics issues. Eskom also uses diesel peaking plants when demand outstrips supply. These fuel costs are pricier and are passed on to customers. With South Africa’s supply-demand imbalance, expensive generators kick in more often—raising cost per unit.
Regulatory Adjustments and Cost-Reflective Tariffs
Eskom’s asks for double-digit tariff increases stem from years of under-recovery. NERSA approved a 12.7% hike for 2025/26—below Eskom’s 36% request—to balance consumer relief with operational cost recovery. Future hikes—5.4% in 2026 and 6.2% in 2027—are expected as part of the adjustment trajectory.
Corruption, Sabotage, and Mismanagement
Corruption and sabotage within Eskom have cost billions and disrupted generation. Former CEO Andre de Ruyter pointed to groups within Eskom siphoning off money and equipment. These losses inflate costs and heighten tariff pressure.
Load-Shedding and Economic Impact
Frequent load-shedding disrupts business and reduces economic output by up to 20%. That affects Eskom’s revenue—losses it then tries to recover through higher tariffs. The vicious cycle continues: less stable supply means higher costs.
Transition to Renewables—Expensive but Vital
Eskom plans to shift toward renewable energy—adding up to 32 GW by 2040. Yet building solar, wind, and gas infrastructure costs money. Combined with old coal-plant costs, this transition adds to tariff pressures before long-term savings emerge.
Global Price Comparisons
At $0.19 per kWh, South Africa’s residential electricity sits around the midrange globally—17% above the world average and nearly 50% higher than the regional average. Businesses, meanwhile, pay more, reflecting Eskom’s tight supply and infrastructure constraints.
Consumer Consequences and Coping Strategies
High electricity costs hurt households—especially those earning below the average wage. Many shift to solar, use energy-efficient appliances, or cut usage. Despite upfront costs, rooftop solar pays off faster amid escalating tariffs.
What Comes Next for Consumers
Expect further tariff hikes and possible tiered or inclining block tariffs under NERSA proposals. Government talks include cross-subsidies to protect low-income consumers, along with new taxes on power-intensive industries. Community advocacy and financial literacy will matter more than ever.

Conclusion: Why is electricity expensive in South Africa
Why is electricity expensive in South Africa? It’s a web of aging infrastructure, swollen debt, operational inefficiencies, corruption, and a long overdue shift to renewables. Every cent on the bill has a story. And while reforms are underway, relief won’t be immediate.
Consumers pay the price today—and unless debt is controlled, corruption cleansed, and supply fixed—the bills will stay high.
