South Africa’s Data Centre Boom Runs Into a Water and Power Test

South Africa’s data-centre boom has become a test of whether Africa’s digital infrastructure growth can be made compatible with water security, electricity planning and public accountability. Civil society groups are calling for a pause on new data-centre construction in the country until the use of scarce water, land and electricity resources has been properly investigated. The Associated Press reported on September 4 that the South African Human Rights Commission has received more than 250 submissions after calling for public input earlier this year.

The concern is not abstract. South Africa has positioned itself as Africa’s primary data hub, hosting a dominant share of the continent’s data-centre capacity and attracting cloud and digital infrastructure projects linked to companies such as Amazon, Microsoft and Equinix. Government sees the sector as a route into the global digital economy. Civil society groups argue that the expansion is moving faster than disclosure rules, environmental scrutiny and local accountability.

The latest flashpoint is an Equinix hyperscale facility approved for Cape Town, a city whose recent history includes the 2018 Day Zero water crisis, when officials warned that taps could run dry. The AP report noted concerns over the electricity demand of the planned facility, estimated at about 160 megawatts. South Africa has also only recently emerged from years of severe loadshedding, making any large new power demand politically sensitive even when Eskom says it has a current surplus.

The digital hub dilemma

South Africa’s position is commercially logical. It has stronger grid infrastructure than many regional peers, better connectivity, deep financial markets, a large corporate customer base and an existing technology ecosystem. For cloud providers, banks, media companies, AI services and multinational firms, local data infrastructure reduces latency and can support data-sovereignty requirements. For government, the sector promises investment, jobs and a stronger role in Africa’s digital economy.

But data centres are not weightless. They need land, steady power, backup systems, cooling, water or water-saving technologies, fibre links and physical security. As artificial intelligence increases global compute demand, data-centre development has become one of the most contested infrastructure stories in the world. Communities want to know who pays for grid upgrades, how much water is used, what energy sources are being consumed and whether benefits are fairly shared.

South Africa’s debate is therefore part of a global pattern, but it has specific local intensity. The country has lived through water stress, power shortages and rising electricity tariffs. Public tolerance for opaque infrastructure deals is low. If data centres are perceived as consuming resources while households and small businesses face higher costs, political resistance will grow.

Transparency is the central issue

The strongest argument from civil society is not simply that data centres should be rejected. It is that the sector needs clearer rules before it expands further. University of Cape Town academic Pitso Tsibolane told the AP that serious investors are not deterred by clear rules, and that uncertainty is worse when a boom is unregulated. That point matters because it reframes the debate. Regulation is not automatically anti-investment. Good regulation can make investment more durable.

At present, critics say operators are not required to disclose enough binding information about water, electricity and land use. Without those numbers, communities and regulators are forced to evaluate proposals without a full understanding of resource impact. That weakens trust and creates the impression that major digital infrastructure is being approved behind a veil.

Data-centre operators and industry groups dispute the most alarmist readings. They argue that South African facilities use newer technologies to minimize water consumption and increasingly rely on renewable energy. Sasha Booth-Beharilal, chairperson of the Internet Service Providers Association, told the AP that data-centre energy demand is not driving electricity scarcity or tariff increases. That argument deserves to be heard, but it also strengthens the case for transparent disclosure. If the sector’s resource use is lower than critics fear, clear data should help prove it.

The Eskom surplus question

Eskom’s reported power surplus has changed the immediate electricity conversation, but it has not ended it. A surplus today does not guarantee resilience tomorrow. Industrial demand can recover, old plants can fail, new transmission constraints can appear, and regional power needs can shift quickly. A data-centre facility that needs large, uninterrupted electricity supply becomes part of long-term system planning, not a simple customer connection.

There is also a distributional issue. If surplus electricity is sold to data centres while communities still face unreliable local service, tariff pressure or underinvestment in municipal infrastructure, public anger will be predictable. The sector must therefore show how it contributes to grid stability, renewable procurement and local economic value rather than only extracting capacity.

One practical route is binding commitments around renewable power, storage, demand response and disclosure of projected electricity use. Another is clearer municipal and national coordination so that data-centre approvals are evaluated alongside water plans, grid plans and industrial policy. Fragmented approvals create avoidable conflict.

Water risk in Cape Town

Cape Town’s Day Zero memory gives the debate a sharp edge. Data-centre companies may argue that modern facilities can reduce water use dramatically, and that some cooling systems consume far less water than older global designs. That may be true, but public confidence depends on site-specific evidence. A facility in a water-stressed city needs to disclose expected consumption, cooling technology, contingency plans and protections during drought.

The issue is not only litres consumed under normal conditions. It is also resilience under stress. What happens during a dry year? Who has priority if water restrictions tighten? Are facilities using potable water, recycled water or air-cooled systems? Are commitments enforceable or merely aspirational? These are not anti-technology questions. They are basic infrastructure governance questions.

AI raises the stakes

The rise of AI makes the question more urgent. Data-centre demand is no longer driven only by email, storage, banking systems or streaming. AI training and inference can require heavy compute loads, and global technology companies are racing to secure sites with power, land and connectivity. Africa will need more compute capacity if it wants to participate in AI development, host local services and reduce dependence on overseas cloud infrastructure.

That creates a strategic tension. Blocking data-centre growth entirely would weaken South Africa’s digital ambitions and could push investment elsewhere. Allowing rapid growth without transparent rules could create environmental backlash and undermine public trust. The sensible path is neither a blank cheque nor a blanket moratorium. It is a regulatory framework that requires disclosure, resource accounting, environmental safeguards, community consultation and enforceable commitments.

What South Africa should demand

The policy requirements are not exotic. South Africa can require project-level disclosure of expected electricity demand, water consumption, cooling technology, backup generation, emissions profile, land use and grid-upgrade implications. It can require renewable-energy procurement plans and public reporting after facilities begin operating. Municipal approvals can include drought-response obligations and community-benefit commitments. National policy can define how data-centre growth fits into industrial strategy, AI policy and grid planning.

The government should also distinguish between types of facilities. Not every data centre has the same footprint. Smaller enterprise facilities, hyperscale cloud campuses and AI-heavy compute sites have different resource profiles. Regulation should be precise enough to avoid treating all projects as identical, while still giving communities reliable information.

For investors, clarity is preferable to confrontation. A sector that waits until civil society forces public inquiries will face delays, legal risk and reputational damage. Companies that disclose early, procure cleaner power, minimize water use and engage communities will have a stronger license to operate.

The bottom line

South Africa’s data-centre debate is not a rejection of the digital economy. It is a demand that digital infrastructure be treated like real infrastructure, with real resource costs and public obligations. The country can remain Africa’s data hub, but it must prove that cloud and AI investment will not quietly intensify water stress, grid pressure or public mistrust.

The outcome will matter beyond South Africa. Other African countries are also trying to attract data centres, cloud regions and AI infrastructure. If South Africa builds a transparent, enforceable model for resource disclosure and community accountability, it can set a continental standard. If it allows an opaque boom, it risks turning one of Africa’s most important digital opportunities into another fight over who benefits from scarce resources.
