An AI data centre requires specialised infrastructure, reliable connectivity and enormous computing capacity. As demand for artificial intelligence grows, South Africa is becoming one of Africa’s leading locations for these facilities.
As AI adoption accelerates, additional computing capacity will be required. This raises an important question: where is the most likely location for South Africa’s next major AI data centre?
Based on existing infrastructure, customer demand and current investment, Gauteng is the strongest candidate—particularly the Johannesburg, Midrand and Centurion corridor.
Why South Africa Needs More AI Data Centres
Traditional data centres already support websites, mobile applications, financial systems, cloud storage and business software. An AI data centre must support particularly demanding computing workloads. Training and operating advanced AI models requires specialised processors, high-density servers, powerful networking equipment and advanced cooling systems. Businesses are also increasingly looking for local cloud infrastructure.
Hosting information within South Africa can provide benefits such as:
- Lower latency
- Faster access to applications
- Improved service reliability
- Easier compliance with data-governance requirements
- Reduced reliance on overseas infrastructure
- Better support for local AI development
South Africa already hosts a significant portion of Africa’s hyperscale data-centre capacity. During the 2026 Google Cloud Summit, President Cyril Ramaphosa stated that the country houses approximately 70% of Africa’s hyperscale data-centre capacity.
This gives the country a substantial advantage as demand for African cloud and AI services grows.
Why Gauteng Is the Leading AI Data Centre Location
Gauteng is South Africa’s primary economic and corporate centre.
Johannesburg and Pretoria are home to major banks, telecommunications companies, retailers, government departments, technology providers and corporate headquarters. These organisations are among the most likely customers for local cloud and AI infrastructure.
Locating an AI data centre near these customers can reduce latency and provide easier access to:
- Enterprise clients
- Telecommunications networks
- Fibre infrastructure
- Cloud-service providers
- Technical contractors
- Skilled employees
- Business partners
Gauteng also has an established data-centre ecosystem.
Existing facilities make it easier for operators to connect customers to multiple cloud platforms, telecommunications providers and internet exchanges. Creating additional capacity within an established market can be less risky than attempting to build an entirely new technology hub elsewhere.
Why Johannesburg Has a Major Advantage
Johannesburg is already one of Africa’s largest data-centre markets.
The city provides access to South Africa’s largest concentration of enterprise customers and extensive national fibre connectivity. Data centres often benefit from being built near other facilities. This allows operators and their customers to exchange information more efficiently, connect to different service providers and create backup systems across multiple locations.
Once a city develops this type of digital ecosystem, it becomes difficult for newer locations to compete. Johannesburg therefore has a powerful advantage: it would not need to build an AI infrastructure sector from the beginning. The city already has many of the networks, customers, suppliers and technical professionals required to support continued expansion.
Why Centurion Is a Strong Candidate
Centurion sits between Johannesburg and Pretoria, giving it access to both major markets. Its location provides proximity to corporate customers, government institutions, national transport routes and established fibre infrastructure. The area also offers more space for large developments than many densely built parts of Johannesburg.
An AI facility requires more than a server room. Large developments may need space for:
- Multiple data halls
- Cooling infrastructure
- Backup generators
- Battery storage
- Electrical substations
- Security systems
- Offices and technical facilities
- Future expansion
This makes available land an important consideration.
Centurion’s position between South Africa’s commercial and administrative capitals makes it one of the most likely locations for a new Gauteng AI data centre.
Could Cape Town Host the Next Facility?
Cape Town remains a strong alternative to Gauteng. The city has an established technology and startup sector, international connectivity and access to several undersea cable systems. It also has a growing ecosystem of software companies, financial technology businesses, cloud providers and technology professionals.
The Western Cape’s renewable-energy potential could make the region attractive to operators that want to reduce their dependence on conventional grid electricity. However, water availability remains a sensitive issue.
High-performance AI processors generate substantial heat, and some data centres depend on water-intensive cooling systems. Cape Town’s previous water shortages mean that any large facility would face scrutiny regarding its environmental impact and resource consumption. A development using closed-loop cooling, air cooling or other water-efficient technologies could still make Cape Town competitive. The city therefore remains one of the strongest alternatives, particularly for facilities prioritising international connectivity and renewable energy.
Durban Is Becoming an AI Data Centre Contender
Durban also has several strategic advantages.
The city is connected to international submarine cable routes and provides access to important logistics, manufacturing and industrial markets. Its coastal position creates opportunities for international connectivity, while KwaZulu-Natal offers more geographic diversity for companies that do not want all their infrastructure concentrated in Gauteng and the Western Cape.
In April 2026, eThekwini Municipality confirmed discussions about the possible development of an AI data centre south of Durban. This does not guarantee that the proposed development will proceed. However, it demonstrates that Durban is attracting serious interest as a future AI infrastructure location.
The city could become an important secondary data-centre hub if developers can secure sufficient electricity, connectivity, land and cooling resources.
Electricity Will Influence the Final Decision
An AI data centre requires enormous and continuous amounts of electricity. Unlike ordinary office buildings, data centres operate around the clock. Even short interruptions can affect customers, financial systems, websites and essential business applications.
A suitable location must therefore provide:
- Reliable grid capacity
- Backup power systems
- Access to renewable energy
- Battery-storage options
- Space for electrical infrastructure
- Reliable fibre connectivity
- Efficient cooling
- Physical security
South Africa’s history of electricity shortages means developers cannot assume that the national grid will always provide sufficient capacity.
New facilities may need private renewable-energy agreements, battery storage and dedicated backup generation. The International Energy Agency’s analysis of AI and energy demand projects that global data-centre electricity consumption could more than double by 2030. This means access to electricity may become more important than proximity to a major city when companies select future locations.
Water and Cooling Cannot Be Ignored
Electricity is not the only resource under pressure.
High-density processors produce substantial amounts of heat. Without adequate cooling, equipment can become unreliable or fail entirely. Some cooling systems use significant quantities of water. This can create environmental and social concerns in areas where communities are already experiencing supply constraints.
Future data-centre developers will therefore need to consider:
- Local water availability
- Closed-loop cooling systems
- Air-cooling technology
- Recycled or non-potable water
- Local climate conditions
- Heat-reuse opportunities
- Environmental reporting
The most attractive location will not simply be the area with the cheapest land. It will be the location that can provide sustainable access to electricity, water, cooling and connectivity.
Connectivity Is Just as Important as Electricity
A data centre must exchange enormous volumes of information with customers, cloud platforms and other facilities. Reliable fibre connectivity is therefore essential.
Operators generally look for locations with access to multiple network providers. This reduces the risk of a single damaged cable or provider outage disconnecting the entire facility. Johannesburg, Cape Town and Durban all benefit from established fibre routes, but they serve different connectivity requirements. Johannesburg provides strong access to South Africa’s largest corporate market. Cape Town and Durban provide strategic connections to international submarine cables.
As networks expand, technologies such as IPv6 will also become increasingly important for supporting a growing number of connected devices and services. Our article explaining why IPv6 is not yet widely used examines some of the challenges involved in upgrading internet infrastructure.
Cybersecurity Must Be Built Into the Facility
An AI data centre would store and process valuable information belonging to businesses, governments and individuals. That makes it an attractive target for cybercriminals. Security must therefore extend beyond guards, cameras and access cards. Operators also need to protect cloud environments, user accounts, APIs, databases and network connections.
Cybersecurity controls should include:
- Strong identity and access management
- Multi-factor authentication
- Continuous network monitoring
- Encryption
- Vulnerability testing
- Incident-response procedures
- Secure cloud configurations
- Backup and recovery systems
Our guide to API and cloud security for South African businesses explains why modern organisations can no longer rely entirely on traditional perimeter security. Any future facility will need to demonstrate that it can protect both physical infrastructure and the information processed inside it.
Could an AI Data Centre Be Built Outside the Major Cities?
Johannesburg, Cape Town and Durban are the most obvious candidates, but future facilities may not need to be located directly inside major cities.
Developers could consider areas with:
- Affordable land
- Access to renewable energy
- Cooler environmental conditions
- Lower water stress
- Strong fibre connections
- Proximity to power-generation projects
A more remote location could reduce property and cooling costs.
However, it would still need reliable connectivity, adequate security and access to technical employees. Building far from existing infrastructure can also increase construction and maintenance expenses. The most realistic outcome may therefore be facilities built on the outskirts of major economic centres rather than in completely remote locations.
The Most Likely Location
Based on existing infrastructure, customer demand, fibre connectivity and access to technical expertise, Gauteng remains the most likely province for South Africa’s next major AI data centre. Within Gauteng, the Johannesburg–Midrand–Centurion corridor is the strongest candidate.
Cape Town remains highly competitive because of its technology sector, renewable-energy potential and international connectivity. Durban is also emerging as a serious future contender, particularly if its proposed AI infrastructure projects proceed.
Ultimately, the final decision will depend on more than available land.
Electricity capacity, water security, environmental approval, network connectivity, cybersecurity and proximity to customers will determine where the next generation of South African AI infrastructure is built.
