A rezoning that didn't survive contact with an appeal
On July 14, 2026, Cape Town's Municipal Planning Tribunal approved Equinix's rezoning application for a hyperscale data centre campus at King Air Industria, clearing the way for one, possibly two, facilities on land the US operator bought as part of a R7.5-billion commitment to South African and African capacity (TechCentral). It did not stand for long. On August 6, the Housing Assembly — a Cape Town housing-rights movement — and the UK digital-rights group Foxglove, represented by the Legal Resources Centre, lodged a formal appeal. Under Section 105(2) of the city's planning by-law, that appeal automatically suspends the approval until the Planning Appeals Authority, chaired by the executive mayor, rules (Mail & Guardian). By mid-September, Deputy Mayor Eddie Andrews confirmed the city is now drafting dedicated development guidelines for hyperscale facilities — while acknowledging it isn't yet clear whether they'll bind applications already in the pipeline.
The steelman: the objectors have a real point
Before relitigating the merits, it's worth taking the appeal seriously on its own terms. Foxglove and the Housing Assembly aren't arguing data centres shouldn't exist in South Africa — they're arguing the city approved one without knowing basic facts about it. Their objection describes Equinix's submission as "a 24-page motivational letter that says nothing about water, nothing about emissions, limited on electricity, nothing about diesel generators" (Foxglove). That's not a technicality. A facility of this scale — Equinix's own figures put 172MW of capacity already under construction elsewhere in its South African portfolio and 160MW more planned — draws power and water at industrial scale, in a city that came within months of "Day Zero" taps running dry in 2018. One estimate puts the two proposed King Air facilities' water draw at roughly 1.2 billion gallons a year, equivalent to the daily use of about 68,500 Cape Town residents, and electricity demand around 157MW — enough for some 250,000 households annually (Tech Policy Press). Approving that without requiring the applicant to disclose the numbers first is a legitimate process failure, not activist overreach.
A continental pattern, not a Cape Town quirk
The underlying problem is that South African municipal planning law doesn't yet have a land-use category for "hyperscale data centre" — these applications get processed as generic industrial or warehouse use, which triggers none of the water- and grid-impact disclosure a facility of this size would face if built as, say, a smelter. Cape Town isn't unique here: Durban's municipality has acknowledged it has "no specific definition for hyperscale or AI data centers" even as it explores a proposed $3–10 billion Korean-backed AI data centre on municipal land with water and electricity requirements still undetermined (Tech Policy Press). Housing Assembly chairperson Kashiefa Achmat has drawn the logical conclusion from that gap, telling Rest of World: "What we are saying is there should be a moratorium on data centers. … It must be across South Africa" (Rest of World). South Africa hosts the continent's largest concentration of data centres, and McKinsey projects African compute demand could hit 2.2 gigawatts by 2030 — roughly five times current levels (Rest of World). The regulatory gap Achmat is pointing at is real and continent-wide.
Where the moratorium logic overreaches
But a blanket pause is the wrong instrument for a definitional problem. Data centre investment decisions are made years ahead of construction, and capital is mobile: Equinix has already characterized the King Air site as a "long-term land bank" with no site development plan yet filed (TechCentral). Signal to global operators that South African municipalities may freeze or retroactively unwind approvals wholesale, rather than fix the disclosure requirements that let this application through incomplete, and the marginal facility simply gets sited in Kenya, Nigeria, or the UAE instead — without making Cape Town's water table any safer. That would forfeit the jobs, grid investment, and digital-infrastructure buildout the demand curve Rest of World cites is going to happen somewhere on the continent regardless.
The retroactivity question Andrews flagged deserves a narrower answer than either extreme. Applying brand-new guidelines to kill an application that already ran the gauntlet of an appeal under the old rules would punish an operator for a regulatory gap it didn't create, and would chill exactly the kind of long-horizon infrastructure commitment McKinsey's demand curve assumes keeps materializing. The Section 105(2) appeal mechanism already does the retroactive work that matters here: it forces Equinix to supply the missing water, power, and emissions data before the suspended approval can be reinstated. What the city's new guidelines should do prospectively is codify that disclosure as a bright-line requirement — a defined "hyperscale data centre" land-use category with mandatory water- and grid-impact figures attached at the rezoning stage, not deferred to a site development plan filed after approval. That answers the objectors' actual grievance — opacity — without treating every future data centre application as presumptively illegitimate.
The fix is definitional, not prohibitive: give hyperscale facilities their own zoning category with disclosure obligations attached, rather than pausing the sector while municipalities decide whether they're allowed to exist.
