Thyspunt emerges preferred site for Eskom’s 5200MW nuclear build

• Proposed plant to deliver up to 5 200 MW of low carbon baseload power.
• Thyspunt in Eastern Cape identified as preferred site, subject to further study.
• Public review of Draft Scoping Report runs from 1 April to 5 May 2026.

Eskom Holdings SOC Limited is moving forward with plans to develop a new nuclear power plant aimed at strengthening South Africa’s long term energy security and reducing reliance on fossil fuels. The proposed facility would add up to 5 200 MW of generation capacity, supporting a stable and low carbon electricity supply in line with national energy policy.

The utility is considering two coastal locations for the project, namely Thyspunt in the Eastern Cape and Bantamsklip in the Western Cape. Following the release of the 776 page 2026 Draft Environmental Scoping Report prepared by WSP, Thyspunt has been identified as the preferred site for further assessment, primarily due to grid access advantages. However, the site also presents notable sensitivities, including its designation as a Grade I cultural landscape.

The project is currently undergoing the Scoping and Environmental Impact Reporting process, a statutory requirement that evaluates potential environmental and social impacts across the full project lifecycle, including construction, operation and decommissioning. The assessment adopts a technology neutral Plant Parameter Envelope approach, allowing flexibility in reactor selection at a later stage.

Independent specialists are conducting studies across a wide range of disciplines, including biodiversity, marine and coastal systems, water resources, traffic, noise, visual impact, radiological risk, socio economic conditions and public health. Early findings indicate that heritage and marine ecology issues will require detailed investigation during the next phase.

Public participation remains central to the process. Stakeholders are invited to review the Draft Scoping Report and submit comments during the review window, with all inputs to be captured in a formal Comments and Responses Report. Public meetings are also scheduled to facilitate engagement with affected communities and interested parties.

The Draft Scoping Report outlines the project description, alternatives considered, regulatory process and proposed specialist studies. It also confirms the recommendation to carry Thyspunt forward into the detailed Environmental and Social Impact Assessment phase.

The forthcoming assessment phase will provide a more comprehensive evaluation of identified risks and mitigation measures. A final decision on project approval will rest with the competent authorities, subject to compliance with South Africa’s environmental and nuclear safety regulations.
