South Africa’s plans for Africa’s second nuclear power facility, at Duynefontein near Cape Town, are still alive. The proposed project, with a planned capacity of 4,000 MW, aims to diversify the country’s electricity generation mix and enhance energy security. Environmental authorization for the site has been upheld, and regulatory processes are ongoing as the government and Eskom move toward final approvals and project implementation.
In contrasting development, South Africa’s Supreme Court of Appeal annuls Eskom’s permit to build a 3 GW gas power plant. The Sept 17, 2025 ruling cites inadequate public consultation as a major reason for the pull on permit.
Reported August 12, 2025 – State-owned South African Nuclear Energy Corporation (Necsa) welcomes the upholding of approval plans for Africa’s second nuclear power plant. The entity seconded the upholding of the decision to grant Eskom environmental authorization to build the plant.
The 2017 decision to grant environmental authorization to build Africa’s second nuclear power plant was upheld after environmental groups raised concerns and appealed against the project. Forestry, Fisheries and Environment (DFFE) Minister, Dr Dion George, also upheld the decision following the appeal.
South Africa seeks to advance its nuclear power fleet as it remains integral in the country’s baseload energy mix. Furthermore, it is part of the government’s strategy to reduce greenhouse gas emissions. Necsa also supports initiatives that reinforce the use of nuclear technology and its applications for power. It also seeks to use the technology in peaceful ways and progress the country’s development.

The Significance of Africa’s Second Nuclear Power Plant in South Africa
Construction of Africa’s second nuclear power plant in South Africa is expected to be of immense significance. Its development is also integral in strengthening South Africa’s energy security.
Additionally, the plant will be built while upholding the highest standards of environmental protection and regulatory compliance. Necsa also notes that these standards will be upheld as demonstrated by Eskom over the years in their operation of the Koeberge nuclear power plant.
Necsa Group CEO, Loyiso Tyabashe, celebrated the milestone, stating:
“This approval marks an important milestone for the nuclear industry and South Africa’s journey towards implementing a balanced energy mix.”
Tyabashe also noted that the decision by the Minister shows the rigor of the process. The CEO went on to highlight confidence in nuclear technology as a safe, clean, and reliable energy option.
Necsa continues to work with the Department of Electricity and Energy and Eskom as a partner. It will also contribute its technical expertise to maximize the benefits of nuclear energy.
