South Africa’s power utility, Eskom Holdings SOC Ltd, and China’s state-owned Power China represent two distinct approaches to energy generation and management, reflecting the unique economic, environmental, and political landscapes of their respective nations. As South Africa grapples with chronic energy insecurity, exemplified by persistent load shedding, a recent visit by Minister of Electricity and Energy, Dr. Kgosientsho Ramokgopa, to China marks a pivotal step toward strengthening the country’s strained power grid through international collaboration.
Eskom, South Africa’s primary electricity supplier, has long been the backbone of the nation’s energy sector, generating around 90% of the country’s electricity. With an installed capacity of approximately 48 gigawatts (GW), Eskom relies heavily on coal, which accounts for over 80% of its energy mix, supplemented by nuclear, hydroelectric, wind, and solar sources. However, the utility has faced significant challenges in recent years, including aging infrastructure, financial mismanagement, and operational inefficiencies. These issues have led to frequent load shedding—scheduled power cuts to prevent grid collapse—disrupting economic activity and eroding public trust. According to Eskom’s 2023 reports, the utility struggles with a high unplanned capacity loss factor, often exceeding 30%, due to frequent breakdowns at its coal-fired plants. Despite efforts to integrate renewable energy and independent power producers (IPPs), Eskom’s transition to a sustainable energy future remains slow, constrained by policy delays and funding shortages.
In contrast, Power China operates on a vastly different scale and with a more diversified portfolio. As one of the world’s largest power engineering and construction companies, Power China boasts an installed capacity exceeding 200 GW globally, with expertise spanning thermal, hydroelectric, wind, and solar power projects. China, the world’s largest energy producer, generated 8,585 terawatt-hours (TWh) of electricity in 2023, with Power China playing a key role in this output. Unlike Eskom, Power China benefits from strong state support, enabling rapid deployment of renewable energy projects. For instance, China’s hydropower capacity alone stands at 416 GW, the largest globally, while wind and solar capacities are projected to account for 70% of the country’s electricity by 2050, according to the Energy Transitions Commission. Power China’s global reach, including projects in over 100 countries, underscores its technical prowess and ability to deliver large-scale energy solutions, often under the Belt and Road Initiative.
The structural differences between the two entities are stark. Eskom operates as a vertically integrated utility, managing generation, transmission, and distribution, whereas Power China focuses on project development, construction, and operation, often partnering with local utilities or governments. Eskom’s monopoly has been criticized for stifling competition, while Power China thrives in a competitive, state-driven environment that encourages innovation and efficiency. Financially, Eskom is burdened with a debt of over 400 billion ZAR (approximately $22 billion USD), while Power China, backed by the Chinese government, has access to substantial capital for investment.
South Africa’s energy crisis has prompted a search for international partnerships, culminating in Minister Ramokgopa’s strategic visit to China on April 7, 2025. During this visit, Ramokgopa engaged with Power China to explore innovative solutions for enhancing South Africa’s energy capacity. The discussions, marked by a symbolic exchange of a ceremonial plate, signal a deepening of ties following President Cyril Ramaphosa’s state visit to China in September 2024. For South Africa, this collaboration offers access to Power China’s expertise in renewable energy and grid modernization—critical for addressing load shedding and transitioning to a more reliable energy system. By leveraging Power China’s experience, Eskom could accelerate its renewable energy projects and improve grid stability, potentially reducing the economic losses caused by power outages, which cost South Africa an estimated 5% of GDP annually.
In conclusion, while Eskom and Power China operate in vastly different contexts, their potential partnership represents a beacon of hope for South Africa’s beleaguered power sector. The minister’s visit underscores a proactive approach to tackling load shedding and building a sustainable energy future, with Power China’s technical and financial resources offering a lifeline to a nation in dire need of energy reform.
