A reservoir
for data centres.

He called it a reservoir. This chapter asks what fills it. South Africa has the deepest data-centre market in Africa. What it does not yet have is dependable power, and the operators winning here are the ones who stopped waiting for the public grid.

Analyst overview

What the South Africa picture actually shows.

The market is the deepest in Africa. The constraint is not capital, land, or skills. It is power you can depend on.

South Africa enters 2026 as the continent's anchor data-centre market: around 56 facilities, roughly 40% of Africa's data centres, and by power the majority of the continent's operational capacity. The market is valued at USD 2.55 billion in 2025 and is projected to roughly double to USD 5.28 billion by 2031. AWS and Microsoft Azure run cloud regions in the country; Google has announced a Johannesburg cloud region, with no firm launch date. The cable landings, the skills base, and the hyperscaler presence are real and verifiable.

The story of the last decade was load-shedding. By mid-2026 that story has eased: the country is approaching a year without rolling blackouts. But the binding constraint has not disappeared, it has moved. It is now reliability and price. Energy alone exceeds USD 1.2 million per facility per year, a load-shedding risk premium still adds about USD 20 per MWh over the Johor equivalent, and the next limit is transmission capacity, not generation. Utilisation already runs above 83% and is projected past 94% by 2030.

The thesis for the chapter is this: the operators winning in South Africa are the ones who stopped waiting for the public grid and started building their own. Teraco owns a 120 MW solar plant and wheels wind from NOA to its halls. Equinix is funding 160 MW of new capacity off its own balance sheet. The government has now placed data centres on the same tier as energy and ports. The reform that decides the next decade is not generation, it is whether transmission and the new wheeling market can scale fast enough. The operators who have already decoupled, verified below, will define which share of the announced pipeline becomes real.

Exhibit D · the wheeling mechanism
How operators route around Eskom, on paper.
The contract web behind a single wheeled megawatt, and the real Eskom tariff it runs on: time-of-use periods, transmission zones, and the charges a wheeling deal can never avoid. Why self-supply is possible, and why it is not a shortcut past load-shedding.
Open the mechanism
What would have to be true
For the R50 billion to become real capacity, three things have to move at once.

Transmission has to release grid capacity faster than demand grows. Wheeling tariffs and rules have to stay stable enough for operators to underwrite twenty-year PPAs. And the new market has to be independent enough that a self-supplying operator is not competing against its own grid host. South Africa's pipeline is not constrained by capital, land, or skills. It is constrained by dependable power and the grid that moves it. The operators who built their own supply early have bought themselves time. The rest are waiting on a reform that is announced, partial, and disputed.

record
01On the digital economy, the President told Parliament that the country is attracting major investment in digital infrastructure1.
02He stated that 55 data centres have already been built2 in South Africa.
03And that more than R50 billion in investment is expected over the next three years3.
04The year before, he had described the country as a “reservoir” for data centres4.
05New public-private partnership rules, he said, would reduce risk and fast-track projects in energy, water, transport and digital infrastructure5.

Eskom revised unbundling strategy: ministerial approval
Statement · 9 December 2025 · Eskom Holdings
Company
statement
01In December 2025 the minister approved a revised unbundling strategy for Eskom1.
02Under it, transmission assets remain owned by the NTCSA, a wholly owned subsidiary of Eskom Holdings2.
03Advisers had warned that immediate full separation could trigger a cross-default on about R400 billion of Eskom debt3.
04A fully independent transmission operator, established outside Eskom, remains the stated end-state4.
05Eskom described the chosen path as the “fastest and most orderly transition”5.

Approval is a decision, not a completed restructure. It sets the shape of the next phase, not its delivery.
Disputedline 02 · ref 2
The contested core. Keeping transmission inside Eskom is read by critics as a conflict of interest in a market where Eskom also generates. See finding 06.
Verifiedline 03 · ref 3
The R400 billion cross-default risk is the real constraint behind the choice, on the record in Eskom statements and Business Day.
Announcedline 04 · ref 4
The ERAA still requires a fully independent operator within five years. The NTCSA was legally separated as a subsidiary in 2024; independence is the unfinished step.

Eskom frames the slower route as orderly. Whether it is orderly or simply slower is exactly the debate.

The licence is real and dated. It is the regulatory permission to run a market, the institutional half of the reform that wheeling depends on.

A “next step”, in Eskom's own framing. Competition is the destination, not the present state.

Five years is the legal clock. The same end-state the unbundling document sets out, now with a statutory deadline attached.

“Temporarily” doing the operator's job is exactly the conflict critics name: the market operator and a generator sit, for now, inside one group. See finding 06.

Policy and
tariff
01Wheeling delivers power from a generator to a buyer across networks owned by others1.
02ERA amendments let private generators sell directly to private off-takers, ending the single-buyer market2.
03Projects under 100 MW are licence-exempt but must register with NERSA3.
04Crucially, wheeling does not shield a customer from load-shedding4.
05And siting is limited by grid capacity, while the transmission plan still faces fundraising hurdles5.

The legal definition, in Eskom's own tariff book. Wheeling is a contract and an accounting mechanism, not a private wire. The electrons mix on the grid.
Verifiedline 02 · ref 2
The 2021 and 2022 ERA amendments are why finding 03 is possible: an operator can own generation and sell it to itself, across the grid.
Verifiedline 03 · ref 3
The 100 MW exemption took the regulatory brake off self-build. Registration, not a full generation licence, is the bar for most projects.
Verifiedline 04 · ref 4
The point operators learn the hard way. A wheeled PPA credits your bill; it does not keep your halls lit when the system sheds load. Only on-site generation or storage does that.
Watchline 05 · ref 5
Where you can wheel depends on spare grid capacity, and the plan to add it is not fully funded. This is finding 06, seen from the project side.
