South African Environmentalists Challenge Government's Nuclear Energy Plans

South African environmental advocacy groups have voiced major concerns regarding a recent announcement by Electricity Minister Kgosientsho Ramokgopa on the procurement of 2,500 megawatts of nuclear power generation capacity. The criticism unfolded amid debates over the nation's energy policy and the necessary procedures to make nationwide energy determinations.

Makoma Lekalakala, director of Earthlife Africa, highlighted procedural irregularities in Ramokgopa's announcement. According to established norms, the National Energy Regulator of South Africa (Nersa) should make such decisions public, and not the electricity minister. These contentions are rooted in the apparent deviation from expected standards, with Lekalakala emphasizing the lack of a public announcement by Nersa regarding the ministerial determination on the new nuclear generation capacity.

Adding weight to the activists' stance is the absence of an updated Integrated Resource Plan (IRP2023). This crucial document would typically provide the analytical backbone to assess the necessity for additional nuclear generation capacity within the country's energy mix. Without a fully reviewed IRP, doubts arise over both the timing and the rationale behind the push for nuclear power expansion.

While Ramokgopa has described the expansion as compelling and illustrated nuclear power as the "cheapest, safest, and most reliable" energy form, there is strong opposition from various environmental and civil society groups. Executive director of the Southern African Faith Communities’ Environment Institutes, Francesca de Gasparis, conveyed a sense of disbelief resonating through civil society. Independent modelling, she mentioned, indicates that nuclear energy might not be an affordable or necessary addition to South Africa's energy portfolio—neither now nor in the future.

Critics underscore the existing electricity baseload requirements, which purportedly do not necessitate nuclear energy, and claim government motivations may be driven by self-interest rather than genuine energy need. De Gasparis also expressed concern about the lack of evidence that the country can financially accommodate the pace and scale of the nuclear expansion as proposed.

The financial argument against nuclear power has been reinforced by academic voices, such as University of Johannesburg's physics professor Harmut Winkler. In his insights shared with the Mail & Guardian and The Conversation, Winkler pointed out that the exorbitant costs associated with building, maintaining, and eventually decommissioning nuclear facilities render it one of the most costly electricity generation methods. He warned of the potential for "political and economic dependence on the nuclear build sponsor country," raising questions of sovereignty and financial autonomy.

Despite the environmental groups' substantiated objections and citing costs comparisons with other energy sources, Ramokgopa maintains that nuclear power would be economically advantageous for the country. This defense comes at an interesting juncture as South Africa aims to extend the Koeberg nuclear power station's lifespan by an additional 20 years, which has been another focal point for skepticism.

The government currently sits on the cusp of releasing the IRP 2023 with draft approval secured from the cabinet. Still, advocates argue that final resolutions on energy procurement should align with the document's guidance. The 2019 version of the IRP suggests preparation for nuclear procurement but cautiously mentions proceeding at a pace and scale the country can afford—an admonition seemingly overlooked in the current push.

As South Africa grapples with energy policy and infrastructural plans, the controversy highlights critical tensions between economic, environmental, and procedural considerations fundamental to shaping its energy future.
