South Africa

South Africa has a population of approximately 65.5 million and a nominal GDP of around US$479.96 billion, making it one of Africa's largest economies. GDP per capita is estimated at about US$7,500, significantly above the continental average. With roughly 4.35% of Africa's population but close to 17% of its GDP, South Africa's economic weight is considerably larger than its demographic share. This reflects its position as the Africa's most industrialised economy, supported by well-developed financial, transport and industrial infrastructure, as well as major mineral resources including platinum, gold and coal.

South Africa's energy profile differs considerably from the hydrocarbon-focused economies in Africa. The country is not a significant oil or gas producer; instead, its energy system has historically been built around coal-fired power generation, which remains closely linked to its large mining and industrial base. The reliability of electricity supply has therefore become a major economic issue, particularly through the long-running operational and financial challenges of Eskom, the state-owned electricity utility. Its prolonged electricity constraints have weighed on economic activity for years, with real GDP growth remaining weak at 1.1% in 2025 despite a significant improvement in power supply. Load shedding has eased considerably from the severe disruptions seen in 2023, but electricity infrastructure remains a structural constraint alongside broader challenges in transport and logistics.

These pressures are compounded by persistently high unemployment, which stood at 32.7% in Q1 2026, while youth unemployment remains particularly severe. At the same time, the power sector is undergoing significant restructuring, with greater private-sector participation, continued renewable energy investment and the separation of transmission activities from Eskom's generation business. South Africa's energy opportunity therefore lies increasingly in strengthening the power system, expanding and integrating new generation, upgrading transmission infrastructure and supporting the shift toward a more diversified electricity market.

South Africa has one of the highest levels of electricity consumption among the countries covered, with per-capita electricity consumption of approximately 3,551 kWh in 2025, above the global average of about 3,156.5 kWh. However, consumption has fallen considerably from its 2007 peak of 5,214 kWh per capita. This decline reflects the impact of prolonged electricity supply constraints and load shedding, which have limited the amount of electricity available to households and businesses.

The country's electricity generation remains heavily dependent on coal, which accounted for approximately 78% of local generation in 2025. Renewables, including wind, solar and hydropower, contributed around 13.6%, while the balance was supplemented by nuclear energy and electricity imports. Despite coal's continued dominance, renewable generation has expanded steadily, with wind generation increasing from 6,512 GWh in 2021 to 12,480 GWh in 2025. Nuclear power also provides a stable contribution through the Koeberg Nuclear Power Station, while total installed generation capacity stood at approximately 60.2 GW in 2025.

A significant feature of South Africa's recent energy transition has been the rapid growth of private electricity generation, particularly rooftop and embedded solar. Privately owned embedded generation capacity increased from approximately 1.2 GW in 2021 to 7.8 GW in 2025, as businesses, agricultural operators and other large consumers increasingly invested in their own generation to reduce exposure to grid disruptions. This has created a substantial parallel generation market alongside Eskom's traditional utility model.

The electricity sector is also undergoing structural reform. The Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) continues to support the development of utility-scale renewable projects, while the establishment of the National Transmission Company South Africa (NTCSA) as an independent transmission operator in 2024 represents an important step towards separating transmission from Eskom's generation operations and facilitating greater private-sector participation. Looking ahead, the government's Integrated Resource Plan envisages a gradual shift away from coal towards wind, solar, nuclear and gas, although achieving this transition will depend heavily on investment in new generation and transmission capacity as ageing coal plants are progressively retired.
