South Africa’s long-running debate over nuclear power has returned to the spotlight after Eskom reaffirmed its interest in developing a new nuclear generation facility at Thyspunt in the Eastern Cape or Bantamsklip in the Western Cape.
The proposal has resurfaced following the release of the Draft Integrated Resource Plan (IRP) 2025, which outlines the country’s future electricity strategy. While environmental groups argue that the project poses significant ecological risks, Eskom maintains that nuclear energy remains a critical component of South Africa’s long-term energy security plans.
The utility insists that the renewed focus on Thyspunt should not be viewed as a new initiative. Instead, officials describe it as the continuation of planning that dates back more than a decade, when the sites were acquired specifically for possible nuclear development.
South Africa has been seeking ways to diversify its electricity supply after years of power shortages, ageing coal-fired infrastructure and recurring load-shedding. As the country works toward reducing carbon emissions, policymakers continue to weigh the role of nuclear energy alongside expanding renewable generation capacity.
Environmental Concerns Remain a Major Challenge
Opposition from environmental organizations remains one of the biggest hurdles facing the project.
The Thyspunt Alliance, a coalition of residents, environmental campaigners and community stakeholders, has repeatedly warned that a nuclear facility could threaten sensitive coastal ecosystems in the region. Critics point to the area’s internationally recognized biodiversity, squid spawning grounds, wetlands and the popular Seal Point surfing destination.
Environmental groups have previously challenged nuclear-related proposals through legal and regulatory channels, contributing to delays in earlier development efforts.
In response, Eskom says comprehensive environmental studies are currently underway. According to the utility, independent specialists are evaluating potential impacts on marine life, biodiversity, coastal processes and local economic activities as part of the Environmental Impact Assessment process.
The company argues that no final decisions will be made until all regulatory requirements have been satisfied and scientific findings have been reviewed.
Nuclear Seen as Part of Future Energy Mix
Questions surrounding project costs have also emerged. However, Eskom says it is premature to estimate the financial requirements of a future nuclear programme because the project scope, reactor technology and procurement model have not yet been finalized.
The utility is examining several internationally proven reactor technologies, including modular deployment options that could potentially reduce construction risks and improve affordability compared with traditional large-scale nuclear plants.
Eskom further stated that no technology suppliers, contractors or funding partners have been selected at this stage.
Beyond electricity generation, the company believes a future nuclear facility could stimulate economic growth in the Eastern Cape. Potential benefits cited include job creation, infrastructure development, supplier participation opportunities and technical skills transfer.
Supporters of nuclear energy argue that it can provide stable baseload power while complementing renewable energy sources such as wind and solar, which are dependent on weather conditions. Similar arguments have been made in several countries pursuing energy transition strategies while seeking to maintain grid reliability.
The debate reflects a broader global discussion about balancing climate goals, energy security and environmental protection. While many nations are investing heavily in renewable energy, some are also reconsidering nuclear power as a low-carbon source capable of delivering continuous electricity generation.
For Eskom, nuclear power remains an important option in South Africa’s future energy portfolio. For environmental activists, however, the fight over Thyspunt is far from settled, and further public consultations and regulatory reviews are expected to shape the next phase of the project.
