South Africa’s Data-Centre Boom Raises New Questions About Water, Power and Public Disclosure

South Africa’s rapid expansion as Africa’s leading data-centre hub is prompting a new debate over whether the infrastructure supporting the digital economy is growing faster than the rules governing its use of water, electricity and land.

Civil-society organisations have called for greater scrutiny of new data-centre developments, while the South African Human Rights Commission has received more than 250 submissions following a call for public input on the sector.

The issue is becoming increasingly important as global technology companies and infrastructure providers expand their African operations. South Africa already hosts about 70% of the continent’s data-centre capacity, according to President Cyril Ramaphosa, making the country a central hub for cloud computing and the infrastructure required by the growing artificial-intelligence economy.

The infrastructure question

Data centres are becoming critical infrastructure for Africa’s digital economy. They support cloud services, financial technology, telecommunications, government systems and increasingly AI applications.

But the facilities can also place significant demands on electricity networks and, depending on their design and cooling systems, water resources. Those concerns have particular resonance in South Africa, which has experienced both severe water stress and years of electricity shortages.

One proposed Equinix hyperscale facility in Cape Town has become a focal point of the debate. Critics have raised concerns about the scale of electricity required for the development and the wider implications of concentrating energy-intensive digital infrastructure in regions already managing resource constraints.

Transparency rather than a technology freeze

The emerging debate is not necessarily about whether South Africa should continue attracting digital infrastructure investment. The more fundamental question is whether the country has sufficient disclosure, planning and regulatory mechanisms to understand the cumulative demands of a rapidly expanding sector.

According to the Associated Press, the Human Rights Commission has identified the availability and transparency of information on electricity demand, water use, land requirements, environmental impacts and effects on surrounding communities as key issues emerging from its public process.

Industry representatives, meanwhile, argue that modern data centres are increasingly adopting renewable-energy procurement and technologies designed to reduce water consumption. They also contend that the sector should not be blamed for South Africa’s broader electricity and infrastructure challenges.

A wider African challenge

The debate extends beyond South Africa. Across Africa, governments are competing to attract data centres as part of broader strategies to develop digital economies and retain more data and computing capacity within the continent.

That creates a policy challenge. African countries need more digital infrastructure, but large-scale facilities must also be integrated into national plans for electricity generation, transmission, water security and urban development.

The next phase of Africa’s digital transformation may therefore depend not simply on how many data centres are built, but on whether governments and investors can establish transparent rules for how those facilities use public resources.
