Eskom revives Thyspunt nuclear plan as coastal green fight reignites

Eskom has reasserted plans for nuclear development at the Thyspunt site in the Eastern Cape and at Bantamsklip in the Western Cape, saying the proposals are part of a long-term strategy and align with government’s draft Integrated Resource Plan 2025. The revival of the proposals has renewed a long-running conflict with environmental activists over sensitive coastal ecosystems.

Utility frames project as continuation of a planned programme

The power utility said it purchased the Thyspunt and Bantamsklip sites specifically for potential nuclear development and characterised the revival as a continuation rather than a new initiative. Eskom told the media the plans align with the government’s latest energy blueprint, the draft Integrated Resource Plan 2025, which prompted the renewed focus on the sites.

Technology, costs and procurement still undecided

Eskom emphasised that no final project scope, technology selection or procurement decision has yet been made. The utility said a range of internationally proven reactor technologies are being explored, including modular deployment approaches intended to improve affordability and reduce construction risks, and that no technology suppliers or financing partners have been selected at this stage.

Environmentalists warn of coastal harm

Environmental groups and residents, organised in the Thyspunt Alliance, remain a major obstacle to the project. The alliance has warned that a nuclear power station at Thyspunt could threaten sensitive marine ecosystems, squid spawning grounds, wetlands and the Seal Point surf break.

Impact studies and public participation

Eskom said independent specialist studies are being carried out as part of the environmental impact assessment process to assess potential impacts on biodiversity, coastal processes, marine ecosystems and socio-economic activities before any final decisions are taken. The utility also said public consultation is being conducted in accordance with legislative requirements governing environmental impact assessments.

Economic and energy-security case

Beyond energy security, Eskom argued a nuclear power station could bring economic benefits to the Eastern Cape through employment, supplier development, skills transfer and infrastructure investment. The utility maintained that nuclear energy is essential if South Africa is to move away from coal while maintaining a stable electricity supply.

“Nuclear technology doesnt only provide clean and baseload energy, it also provides the flexibility required to support non-dispatchable renewable energy sources,”

The quote above was attributed to Eskom spokesperson Daphne Mokwena. For environmentalists, however, the fight over Thyspunt and the nearby coastal areas continues.
