Eskom has quietly opened talks with the World Bank and other potential financiers as it eyes a multibillion‑dollar nuclear expansion that could be launched within the next twelve months. The state‑owned utility, which already operates Africa’s sole commercial nuclear plant at Koeberg, is drafting a request for information that targets up to 5.2 GW of additional capacity – a move aimed at bolstering baseload supply as the country pivots away from its coal‑dominant grid.
The urgency is palpable. Power cuts have become a regular feature of South African households and industries, and Eskom’s ageing coal fleet struggles to keep pace with growing demand. By adding both conventional pressurised water reactors (PWRs) and smaller modular units, the utility hopes to secure a stable, low‑carbon power source that can run round‑the‑clock, irrespective of weather‑related fluctuations that affect solar and wind.
“We are in exploratory discussions with most of the potential funders … looking for anyone with ideas,” explained Bheki Nxumalo, Eskom’s group executive for generation, at a recent energy conference in Cape Town. The utility’s leadership stressed that funding structures are still fluid, ranging from public‑private partnerships to vendor financing models similar to those employed by Russia’s Rosatom in Egypt.
Eskom nuclear programme: capacity mix and financing routes
| Technology | Proposed Capacity (GW) | Funding Model(s) Explored | Key Benefits |
|---|---|---|---|
| Pressurised Water Reactors (PWR) | 4.8 | Public‑private partnership, commercial bank loans, African Development Bank | Proven technology, large‑scale baseload |
| Small Modular Reactors (SMR) | 0.4 | Vendor financing, Development Bank equity, World Bank guarantees | Faster deployment, lower upfront capital, flexible siting |
| Hybrid coal‑to‑nuclear (SMR‑focused) | 0.2 (subset of SMR) | Joint ventures with coal asset owners | Utilises existing infrastructure, smooth transition |
The table underscores that over 92 % of the planned capacity relies on tried‑and‑tested PWRs, while the remaining share hinges on the newer SMR technology, which many observers view as a lower‑risk entry point for expanding nuclear footprints.
Funding remains the crux of the proposal. Eskom’s balance sheet, strained by years of debt and under‑investment, cannot shoulder the entire cost. The utility is courting a mix of commercial banks, the African Development Bank, and multilateral lenders such as the World Bank, whose recent policy shift has reopened the door to nuclear financing for developing economies.
A World Bank spokesperson confirmed that the institution is reviewing the possibility of support, noting that any engagement would be aligned with “countries’ development priorities and its policy framework, which allows for a range of technologies.” While the bank declined to comment on specific negotiations, its willingness to reconsider nuclear projects signals a broader international appetite for low‑carbon baseload solutions.
The timeline is ambitious. Nxumalo indicated that Eskom plans to go to market for both conventional reactors and SMRs within the next 12 months, a schedule that will require swift resolution of regulatory, environmental and community concerns. Local opposition groups have long warned against expanding nuclear capacity without thorough safety assessments and transparent stakeholder engagement.
Eskom’s pursuit of SMRs also dovetails with its coal‑to‑nuclear strategy, proposing that a portion of the modular capacity be co‑located with existing coal sites. This approach could repurpose existing transmission infrastructure and water resources, potentially reducing the environmental footprint associated with building fresh nuclear sites from scratch.
The financial architecture being explored includes vendor financing, where the reactor supplier assumes a portion of the construction risk and provides credit to the host utility. This model has been highlighted by the Rosatom‑Egypt partnership at El Dabaa, and Eskom appears keen to emulate a similar arrangement if it proves cost‑effective.
In addition to external funding, Eskom is expected to tap into internal cash‑flow optimisation and possible government guarantees to shore up investor confidence. The utility’s recent restructuring efforts have aimed to improve revenue collection and reduce operational losses, steps that could make the nuclear programme more palatable to private financiers.
Stakeholders across the spectrum are watching closely. Industry analysts argue that a successful nuclear rollout could stabilise electricity prices, lower reliance on imported coal, and position South Africa as a regional hub for nuclear expertise. Conversely, environmental NGOs warn that the long‑term waste management and decommissioning costs could outweigh short‑term gains, especially if the projects face delays or cost overruns.
What remains clear is that Eskom’s nuclear ambitions are now moving from speculative discussion to concrete planning. The utility’s willingness to engage multiple funding partners and explore both large‑scale reactors and modular options reflects a pragmatic attempt to reconcile the country’s urgent energy needs with fiscal realities. If the utility can secure the necessary capital and navigate the regulatory landscape within the proposed year‑long window, South Africa could witness a transformative shift in its power generation mix, marking a decisive step away from coal and toward a more diversified, low‑carbon future.
