At Megawatt Park in Sunninghill, South Africa, a power utility once defined by coal is making a deliberate pivot toward the future. On June 9, Eskom—the state-owned utility that has long supplied the bulk of Africa's biggest economy with electricity—launched Eskom Green, a dedicated business unit focused entirely on developing utility-scale renewable energy projects. The move marks a significant shift for a company that built its reputation managing a fleet of coal-fired power stations, now actively dismantling that legacy in favor of clean energy sources.
The stakes are substantial. South Africa faces one of the world's most pressing energy crises, with blackouts routinely crippling the economy. For years, Eskom's aging coal infrastructure has been at the center of that problem, leaving businesses and households searching for alternatives. Against this backdrop, Eskom Green arrives as both an acknowledgment of past constraints and a blueprint for transformation. The unit will initially operate within Eskom Holdings before being separated into a wholly-owned subsidiary with an independent board, allowing it to move with the agility required in the fast-moving renewable sector.
The ambition is striking. Eskom Green aims to deliver approximately 6 gigawatts of carbon-free electricity by 2030, a nearterm milestone that will draw from a pipeline of renewable energy and storage projects already in development. That target is itself a stepping stone toward a far more ambitious goal: 32 gigawatts of total renewable energy capacity by 2040, a transformation that would reshape South Africa's energy profile entirely. To put these numbers in perspective, 6 gigawatts represents enough power to serve millions of households and replace years of coal generation.
The business model is equally shrewd. Eskom Green will target energy-intensive sectors—mining and manufacturing, industries that have historically powered South Africa's economy but are now clamoring for carbon-free power. The unit will offer long-term contracts for renewable power backed by storage solutions, addressing the intermittency concerns that have long plagued renewable energy adoption among industrial users. These are not aspirational gestures but pragmatic offerings designed to appeal to companies making their own sustainability commitments.
Funding has been provisioned within Eskom's approved capital expenditure programme and will be supported through on-balance sheet funding, meaning the utility is backing these pledges with real capital rather than promises. This matters. Previous energy transitions have stumbled when financing proved illusory, but Eskom appears committed to the financial architecture required for success.
What makes this moment significant is context. Eskom's announcement comes as South Africa grapples with Stage 6 blackouts and years of infrastructure neglect. The company's transformation from coal utility to renewable energy developer will not happen overnight, but the structural separation of Eskom Green into its own subsidiary signals seriousness. It creates space for different business cultures, attracts talent focused on renewables rather than thermal generation, and begins the long work of remaking a national institution.
By 2040, if these plans hold, South Africa's power supply could look fundamentally different—cleaner, more resilient, and less dependent on aging coal plants. Eskom Green is not a guarantee of that future, but it is a institution-wide commitment to pursuing it.
