Eskom Green Goes Live: What South Africa’s State Utility Creating a Dedicated Renewables Division Means for African Mining Decarbonisation
What Launched on June 9
On June 9, 2026, Eskom Holdings launched Eskom Green, a dedicated renewable energy business designed to accelerate the development of utility-scale renewable energy projects and support larger power user customers in achieving their decarbonisation and energy transition objectives.
Eskom Green has been designed in response to global benchmarking research on over 20 utilities. The insights indicate that the development of renewable energy projects requires agile decision-making, access to diverse sources of capital, partnership-based delivery models and bankable project structures. These differ materially from Eskom’s legacy vertically integrated generation model. Eskom is not simply adding solar panels to its portfolio. It is acknowledging that the institutional architecture required to develop renewables at scale cannot be built inside the existing utility structure.
The new entity marks a significant strategic shift for the state-owned utility as it positions itself to play a larger role in South Africa’s renewable energy market. Eskom Green is expected to operate as a ring-fenced business with plans to become an independent subsidiary.
The Capacity Numbers
The new wholly owned subsidiary plans to deploy a 6GW portfolio of solar, wind, pumped storage and battery energy storage capacity by 2030, supplying industrial customers under take-or-pay agreements. The portfolio is comprised of 17 high-priority projects that plan to leverage existing infrastructure of Eskom’s existing coal-fired power plants, of which at least 2GW of renewable energy and pumped storage projects are expected to advance through 2026. Among them, the 75MW Lethabo solar plant started construction works in May 2026.
Beyond that, Eskom Green will advance a further pipeline of up to 32GW of renewable energy and storage projects by 2040, financed through dedicated project special purpose vehicles. Eskom indicated that, in terms of technology, the new unit’s pipeline will be weighted toward solar PV, supported by battery energy storage, pumped storage and wind.
The 32GW target by 2040 requires context. When Eskom announced its energy transition roadmap in 2025, it held less than 1GW of operational renewable capacity. The target represents a more than thirtyfold increase over approximately fifteen years. Simultaneously, coal-fired generation capacity would undergo a managed contraction from roughly 39GW to 18GW over the same period, meaning more than half of Eskom’s existing thermal fleet would be decommissioned or repurposed.
The utility estimates that every 10GW of renewable energy capacity requires approximately 6GW of dispatchable generation capacity to maintain system reliability, equivalent to 60% of renewable capacity additions. That ratio is the engineering constraint that makes storage central to Eskom Green’s commercial model. Take-or-pay industrial customers need predictable, round-the-clock supply. Solar without storage does not deliver that. The Lethabo project and the battery energy storage components of the 17-project pipeline are the mechanism that makes baseload renewable supply bankable.
Why Mining Is the Primary Target
Initially, Eskom Green will primarily target sectors with high energy consumption, such as mining and manufacturing, providing them with solutions to decarbonise, for example, through direct bilateral power purchase agreements.
The commercial logic is direct. The launch comes as carbon-content requirements, including the European Union’s Carbon Border Adjustment Mechanism, increase pressure on exporters in carbon-intensive sectors such as steel, aluminium, cement, fertilisers and other industrial products to account for embedded emissions.
South African mining companies, gold, platinum, chrome, manganese, are increasingly facing European and North American buyers who require carbon disclosure and, in the medium term, carbon-adjusted pricing. A mining operation powered by Eskom’s coal-heavy grid is a commercial liability in that environment. Eskom Group Executive for Renewables Rivoningo Mnisi said: “Eskom Green is a utility-scale renewable energy business that rapidly accelerates the options available to South Africa’s industries to decarbonise and transition industrial and productive capacity to maintain export competitiveness.”
The phrase “export competitiveness” is the operative one. The EU CBAM is not an aspiration. It is a pricing mechanism that attaches a carbon cost to the embedded emissions of imports in covered sectors. South African miners exporting platinum group metals, manganese or chrome to European buyers who process them into steel or battery materials are already in scope or adjacent to it. Eskom Green’s direct bilateral power purchase agreements with mining operators are the contractual instrument that allows those companies to document and certify their electricity as renewable, which is what CBAM compliance ultimately requires.
The Execution Problem
Eskom noted that since the release of its 2019 IRP, only about half of the awarded renewable energy projects that had secured grid allocation and power offtake agreements were actually built. The utility indicated that this situation underscores the necessity for improved coordination to safeguard energy security while also meeting emissions-reduction goals.
That admission is the most significant caveat in the Eskom Green announcement. A 50% delivery rate on awarded renewable projects is not a performance record that supports a 6GW by 2030 target with high confidence. The ring-fenced subsidiary structure, the independent board, and the project special purpose vehicle financing model are all institutional design choices that respond to this delivery gap. The question is whether institutional redesign alone is sufficient to overcome the coordination failures, procurement delays, and grid connection bottlenecks that have historically constrained South African renewable deployment.
Eskom carries approximately R450 billion in debt. The financing model for Eskom Green is designed to be self-standing, with projects financed through dedicated SPVs rather than through Eskom’s balance sheet. A comparative review of more than 20 power utility transitions globally found that successful renewable expansion at scale consistently required more agile organisational models capable of accessing diversified capital sources and compressing project delivery timelines. The SPV structure is the mechanism. Whether it is sufficient is the question the 2GW near-term pipeline, advancing from 2026, will begin to answer.
The Continental Reading
Eskom is by far the largest power utility in sub-Saharan Africa, and its institutional choices carry weight beyond its own borders. The Eskom Green launch is the most concrete institutional expression yet of a reckoning that has been building across African state utilities. Nigeria’s NEDC, Côte d’Ivoire’s CIE, Kenya’s Kenya Power — all face versions of the same structural challenge: legacy thermal infrastructure that is too expensive to operate, insufficient capacity to meet industrial demand, and a renewable transition that requires capital structures and governance models that incumbent utilities were not built to deploy.
What Eskom Green represents is a template: ring-fence the renewables business, give it an independent board, target take-or-pay industrial customers first, and build the pipeline on co-located infrastructure at existing coal sites to reduce greenfield costs. The execution risk is real. But the institutional design of Eskom Green is the most credible framework a sub-Saharan African state utility has yet produced for scaling renewables at industrial pace. Whether it delivers on the 2GW near-term milestone is the data point the rest of the continent’s utilities will be watching as closely as Eskom’s own shareholders.
