A post circulating widely across South African social media platforms makes a striking claim: that billionaire Johann Rupert offered to supply South Africans with 67 units of electricity for R10, and that former Mineral Resources and Energy Minister Gwede Mantashe refused to give him a licence to do so. The post has attracted thousands of reactions, shares, and comments. It has also, at every material point, misrepresented the facts.
Billionaire Room has reviewed the verified record. Here is what actually happened, what Rupert actually built, and why the underlying frustration driving the post is still entirely legitimate.
What the Claim Says, and Why It Is Wrong
The viral post asserts that Rupert offered electricity at R10 for 67 units to ordinary South African households, implying a direct consumer offer that was blocked by regulatory obstruction. There is no verified source, no press conference, no regulatory filing, and no corporate announcement anywhere in the public record that supports this specific claim. The figure of 67 units for R10 has no basis in any known statement made by Rupert, his company Remgro, or any entity associated with him.
South Africa’s residential electricity price currently stands at approximately R3.71 per kWh. At that rate, R10 purchases fewer than three units of electricity. For anyone to supply 67 units at R10, the economics would require a subsidy mechanism, a regulatory framework, and an infrastructure model that no private energy player, including Rupert, has proposed or could legally execute at scale for household consumers. The claim, as stated, is arithmetically and operationally impossible under any current or proposed regulatory structure.
What Rupert Actually Built
The facts surrounding Johann Rupert and electricity are real, significant, and worth understanding correctly.
Rupert built a 2.3MW renewable energy hydroelectric plant on his L’Ormarins farm in Franschhoek, valued at approximately R70 million. The plant generates around 6.3 million kWh per year, with an estimated 3.5 million kWh available as surplus to be fed into the national grid.
This is a privately funded, operational clean energy asset. The problem was not a refused licence to sell cheap electricity to households. The problem was that a Power Purchase Agreement signed with Eskom in 2016 was valid for one year and was never renewed, with no reason given. Rupert said the plant had been connected to the grid but could not be switched on due to red tape. “The power is running into the sea,” he said.
That is the real story. A working renewable energy plant producing surplus clean power, unable to contribute to a national grid that was simultaneously implementing rolling blackouts. The dysfunction was real. The scandal was real. But the nature of what was blocked was grid-feeding by a private farm, not a household electricity offer at R10.
What Rupert Actually Launched for Energy
Beyond the hydro plant, Rupert’s business interests have moved meaningfully into the broader energy sector through a different vehicle entirely.
EXSA, previously known as the Energy Exchange of Southern Africa, was founded by Rupert’s Remgro to bring together green energy producers and electricity consumers. In November 2022, NERSA awarded an electricity trading licence to the Energy Exchange. NERSA did not refuse a licence. It granted one.
EXSA delivers electricity by wheeling it from a generator to an end-user using an existing transmission or distribution network. Today, EXSA is a market-leading supplier of grid-connected renewable energy to South African corporates, industrials, and SMEs, with wind and solar energy helping companies meet their net zero ambitions at a lower price than Eskom charges.
This is a corporate energy trading platform, not a household electricity scheme. Its clients are businesses. It does not sell prepaid tokens to residential consumers. The framing in the viral post, that Rupert tried to give ordinary people cheap electricity and was stopped, is not supported by the actual structure or purpose of either the hydro plant or EXSA.
The Legitimate Frustration Underneath the Fiction
None of this diminishes the real anger driving the post’s virality.
Eskom’s revenue grew by 4% to R191.3 billion in the first half of its 2026 financial year, driven primarily by a 12.74% increase in the regulatory standard tariff from 1 April 2025. That tariff increase was not an abstraction. It was felt immediately by every prepaid household in the country. In April 2025, Eskom restructured its residential Homelight tariff from a three-block inclining structure to a single flat rate of R2.49 per kWh, meaning customers who previously used less than 350 kWh per month now pay more per unit than before.
The arithmetic of daily life has become brutal for millions of South Africans. The frustration that finds expression in viral posts is not irrational. It is the consequence of a utility that was genuinely broken, being repaired at a cost falling most heavily on those least able to absorb it.
Eskom reported profit after tax of R24.3 billion in the first six months of its 2026 financial year, with no loadshedding implemented since 15 May 2025. These are real achievements. But they do not reduce the cost of the next token purchase.
The question of whether private clean energy should be reaching households sooner, at more competitive prices, through a properly functioning open market, is entirely legitimate. South Africa’s Electricity Regulation Amendment Act, which came into effect in January 2025, is designed precisely to move the sector in that direction. Whether it does so at a pace and scale that reaches ordinary consumers is the real policy debate worth having.
The Johann Rupert electricity story South Africa should be discussing is not about a fictitious R10 offer. It is about whether the country’s energy transition, now genuinely underway, will be structured in a way that eventually delivers affordable power to households, or whether it will remain, for the foreseeable future, a market serving corporate buyers while prepaid consumers continue to watch their units disappear.
That is a story worth having. The fictional version, however widely shared, is not.
