In July 2024, South Africa created history when the National Transmission Company of South Africa legally unbundled from the state-owned utility Eskom—a landmark moment in a nation urgently reimagining its electricity system. The move marked the most visible sign yet of a broader energy transformation already underway across the country: while coal still powers roughly 80 percent of South Africa's grid, private companies are racing to expand wind and solar capacity, driven by one of the continent's most effective renewable energy programs.
The shift matters because South Africa's energy sector has long been fragile, burdened by aging coal plants, crumbling utility finances, and an electricity affordability crisis that has seen prices rise 720 percent since 2008. For years, nationwide rolling blackouts known as load shedding threatened the economy and daily life. Yet something remarkable has begun to crack that pattern. Peak electricity demand has fallen below 32 GW as businesses and households installed behind-the-meter solar systems—now totaling more than 7 GW and exceeding utility-scale solar capacity—and moved off-grid entirely. A marked improvement in Eskom's coal fleet performance, combined with this reduced demand, has brought relief: much of 2024 and 2025 saw no scheduled blackouts.
The REIPPPP (Renewable Energy Independent Power Producer Procurement Programme) stands at the center of this shift. Since its launch in 2011, the program has attracted $15 billion in private investment and built 93 operational wind and solar projects that now generate more than 6 GW of electricity, with another 2 GW under construction. The results are tangible: solar tariffs have fallen 88 percent and wind tariffs by 70 percent. That success has made South Africa a model other African nations are studying closely.
The government is building on this momentum with sweeping reforms. In August 2024, President Ramaphosa signed the Electricity Regulation Amendment Act, which establishes an independent transmission system operator, creates a competitive electricity market, and imposes penalties for infrastructure sabotage. The NTCSA's operational launch was the first concrete step in unbundling Eskom, though it remains financially linked to the utility while working to establish independence.
Yet vulnerabilities remain. Eskom is mired in billions of dollars in debt, while municipalities owe the utility more than $6 billion, limiting investment in new infrastructure and maintenance. The energy system's fragility also reflects rising transmission constraints and the deepening affordability crisis.
Looking ahead, the government is betting on natural gas as a transitional energy source for manufacturing and baseload power. In January 2024, Transnet appointed Dutch terminal operator Vopak to develop an LNG import terminal at Richards Bay on the east coast, targeting an operational date of 2028 with the capacity to import two million tons annually, ramping to five million tons by early 2030. Eskom plans a 3 GW gas-to-power plant adjacent to the terminal, though environmental groups secured a court victory in September 2025, requiring more robust public consultation on the project.
South Africa's energy future remains contested and complex. But with private renewable investment soaring, demand declining, and legal and regulatory reform finally taking hold, the nation's decades-long dependence on coal appears genuinely threatened—replaced by a diverse system taking shape one wind turbine and solar panel at a time.
