For years, South Africans became accustomed to hearing a familiar phrase: power cuts.
Factories slowed production, businesses installed backup generators, and households adjusted their daily routines around electricity shortages. Now, the country's biggest power company says it wants to change that story.
This month, Eskom officially launched Eskom Green, a new renewable-energy division designed to develop large-scale solar, wind, and battery-storage projects across the country. The move is being viewed as one of the most significant developments in South Africa's energy sector in recent years.
The announcement signals a major shift for a company that has traditionally relied heavily on coal-fired power stations.
A Utility Trying To Reinvent Itself
Eskom remains the backbone of South Africa's electricity system.
For decades, the company supplied most of the nation's power through coal plants. However, aging infrastructure, financial challenges, and repeated electricity shortages have created growing pressure for reform.
Rather than simply repairing old systems, Eskom is now attempting a broader transformation.
The newly created renewable unit will focus on delivering cleaner electricity while also helping energy-intensive industries secure reliable power supplies. The company aims to make around 6 gigawatts of carbon-free electricity available by 2030 through projects currently being developed.
For many observers, the launch marks the beginning of a new chapter.
Why South Africa Needs More Power
South Africa is Africa's most industrialized economy, yet electricity shortages have repeatedly slowed economic growth.
Mining companies, manufacturers, and small businesses have all been affected by unstable power supplies.
Energy experts say one of the country's biggest challenges is not demand itself, but the ability to deliver electricity consistently. Years of underinvestment and aging infrastructure have created bottlenecks that continue affecting economic performance.
Because of these problems, reliable electricity has become one of the most important economic issues facing the country.
Solar And Wind Are Growing Fast
The timing of Eskom's move reflects a wider trend across Africa.
Renewable-energy development has accelerated rapidly during the past few years. According to industry data, Africa added record solar capacity in 2025, with South Africa leading much of that growth. The country already has more than 10 gigawatts of installed solar capacity and plans significant additional expansion during the coming decade.
Private companies are also investing heavily in clean energy.
Large industrial firms, mines, and manufacturers increasingly view solar and wind power as cost-effective alternatives to traditional electricity sources.
Falling technology costs have made renewable projects more attractive than ever before.
The Grid Problem
Ironically, South Africa's success in building renewable-energy projects has created a new challenge.
There are now concerns that the country's electricity grid may struggle to keep pace with growing renewable capacity.
Energy specialists warn that expanding transmission infrastructure is becoming just as important as building new power plants. Without sufficient grid capacity, electricity generated by solar and wind farms cannot always reach consumers efficiently.
This issue has become a major topic among investors and policymakers attending energy conferences across the continent.
Government Seeking Major Investment
Recognizing the scale of the challenge, South Africa has begun attracting international financial support.
Recent agreements with the World Bank include billions of dollars in funding and guarantees aimed at upgrading transport and energy infrastructure. Much of that support is expected to help strengthen electricity networks and reduce bottlenecks limiting growth.
Officials believe modern infrastructure could unlock billions in additional private investment.
The government hopes improved electricity reliability will encourage business expansion and create jobs.
A Future Beyond Coal?
Coal remains central to South Africa's energy system.
However, pressure to reduce emissions and improve efficiency is driving interest in alternative sources.
Eskom has publicly stated that it wants up to 32 gigawatts of renewable-energy capacity by 2040. The company is also exploring battery storage projects that can help balance electricity supply during periods when solar and wind generation fluctuate.
Industry leaders say battery technology will play a critical role in ensuring renewable power remains available even after sunset or during periods of weak wind.
Businesses Watching Closely
The country's mining sector is among those paying close attention.
Mining operations consume enormous amounts of electricity and require stable power to remain competitive.
Several major industrial companies have already announced plans to purchase renewable electricity through long-term agreements.
Business groups argue that a reliable energy system would improve productivity, attract investment, and strengthen South Africa's position in global markets.
For many companies, the question is no longer whether renewable energy will become important, but how quickly the transition can occur.
The Challenge Ahead
Launching a new renewable division is only the first step.
Building projects, expanding transmission networks, securing financing, and maintaining grid stability will require years of sustained effort.
South Africa must also balance its clean-energy ambitions with the reality that millions of people still depend on coal-related jobs and industries.
That makes the transition both an economic and social challenge.
Success will depend not only on technology but also on policy decisions and long-term planning.
A Turning Point For African Energy
Across Africa, renewable energy is becoming one of the fastest-growing sectors.
Solar panels, wind farms, and battery-storage systems are appearing in regions that once relied almost entirely on fossil fuels.
South Africa's latest move places it at the center of that transformation.
Whether Eskom Green ultimately succeeds remains to be seen, but the launch sends a clear message: one of Africa's largest power producers is preparing for a future that looks very different from its past.
For a country that has spent years battling electricity shortages, that future cannot arrive soon enough.
