Cape Town groups demand a moratorium on hyperscale data centres

South African housing and civil-rights groups are challenging two proposed Equinix data centres in Cape Town and asking the national Human Rights Commission for a moratorium on hyperscale expansion until operators disclose resource use and community benefits.

The proposed facilities would total 174 megawatts and, according to the groups, consume more than 4.4 billion litres of water annually—roughly the use of 18,000 homes. That estimate is disputed in spirit by Equinix, which says sustainable design is foundational, but the company did not supply an alternative figure in Rest of World’s account. Cape Town came close to running out of water in 2018, making aggregate annual use a politically tangible measure.

US companies are investing heavily: Microsoft has committed about $300mn to South African AI infrastructure by 2027, AWS plans $1.5bn across Africa through 2029 and Equinix plans $438mn in South Africa. African compute demand could reach 2.2GW by 2030, five times current levels.

The counterargument is equally concrete. Africa holds less than 1% of global data-centre capacity despite containing about a fifth of the world’s population. Local capacity can improve latency, cloud access and digital sovereignty; stopping construction entirely would deepen dependence on infrastructure elsewhere.

The conflict is therefore about terms, not a simple choice between technology and scarcity. Communities want resource accounting and benefits negotiated before approvals become faits accomplis. In a region with constrained grids and water systems, the cost of “local AI capacity” depends on who receives priority when infrastructure is insufficient for everyone.
