South Africa's Energy Crisis: Why the Lights Keep Going Out
The Eskom Monopoly
Eskom, South Africa's state-owned power utility, generates roughly 90 percent of the country's electricity, most of it from coal. It was once a point of national pride — in the 1990s, South Africa had some of the cheapest and most reliable electricity in the world. But decades of underinvestment, corruption, and mismanagement have turned Eskom into a symbol of state failure. Its coal fleet, with an average age of over 40 years, breaks down constantly. Its debt exceeds R400 billion (roughly $22 billion), much of it guaranteed by the government.
The result is load shedding — planned, rolling blackouts imposed when demand exceeds supply to prevent a total grid collapse. South Africans have experienced load shedding in stages since 2007, but the crisis escalated dramatically from 2022 onward, with some years seeing over 280 days of blackouts. The economic cost is estimated at R1 billion to R2 billion per day during severe load shedding. Factories shut down. Water pumps stop. Traffic lights go dark. Cell towers run on backup batteries until they die.
The Coal Trap
South Africa is the world's 14th-largest carbon emitter, and Eskom is the single largest point-source emitter on the continent. The coal plants that cause the emissions also cause the blackouts when they fail. The country is trapped: dependent on coal for baseload power, unable to maintain the coal plants, reluctant to phase them out because of jobs (roughly 90,000 people work in coal mining and related industries), and unable to build replacements fast enough.
The Just Energy Transition Partnership, a $8.5 billion deal announced in 2021 with France, Germany, the UK, the US, and the EU, was designed to break this trap. The money is intended to decommission coal plants, support workers and communities affected by the transition, and accelerate renewable energy deployment. Implementation has been slow — negotiating how the money flows, who controls it, and what conditions are attached has taken years — but the framework is the most ambitious attempt anywhere to manage a just transition from coal.
What Recovery Looks Like
The solution is not a single intervention but a portfolio. New generation capacity from renewable sources — solar, wind, and battery storage — can be built faster and cheaper than coal or nuclear. Independent power producers, which were licensed after electricity market reforms in 2020, are adding gigawatts of capacity. Transmission infrastructure, which is the bottleneck in parts of the country with the best renewable resources, needs massive investment. Eskom itself must be restructured, separating generation, transmission, and distribution into distinct entities to improve accountability and attract private investment.
The crisis is not technically unsolvable. The combination of solar radiation, wind resources, and available land make South Africa one of the best places on Earth for renewable energy. The problem is institutional: a state-owned monopoly that was allowed to deteriorate for decades, a political system that uses Eskom for patronage and procurement, and the absence of the political will to impose the costs of reform on powerful constituencies. Load shedding will end when those institutional problems are solved, not when the next power plant comes online.
