The competition to host Africa’s next wave of digital infrastructure is no longer just about fibre networks or cloud licenses. It is about power. More specifically, who can offer low-cost, always-on, cleaner energy to hyperscalers hungry for land and megawatts.

Two unlikely frontrunners have emerged: Botswana and Nigeria.

Both are promising renewable-powered data centres designed to serve cloud providers, AI compute clusters and industrial-scale digital operations. One is tapping into the desert sun. The other is betting on rivers, reservoirs and natural gas.

What’s unfolding is more than two investment announcements. It is the start of a continental power play over who hosts Africa’s digital future — and on what terms.

Botswana is not usually seen on the African tech map. It has no major startup hubs, no consumer-facing digital brands, and none of the population density that big cloud players tend to chase. Yet it has something silicon cannot resist: stable government and an abundance of sun.

AAAS Energy, a Dutch developer, and ChillMine, a US operator, have signed an agreement to build a high-density data campus near Palapye, positioned between Francistown and Gaborone. The site will be plugged into a 250MW solar farm backed by 100MW of battery storage, and topped up with locally sourced natural gas.

In short — solar by day, battery by night, gas as backup.

The target customers are not domestic enterprises. They are AI training clusters, cloud giants and mining-linked computing operations that care less about geography and more about cost per kilowatt-hour.

Botswana is not pitching itself as a digital hub. It is pitching itself as Africa’s most predictable power station — with server racks attached.

While Botswana is building far from population centres, Nigeria is doing the opposite.

Nugi Group, a software company, plans to build a Tier IV data centre in Calabar, far outside the usual tech corridors of Lagos and Abuja. The location is not a sacrifice. It is a strategy. Calabar offers access to water for hydro generation, land for solar fields and nearby gas infrastructure.

In effect, water, sun and gas in one cluster.

More importantly, Nigeria already has traffic, developers and digital demand. Hosting servers closer to users means lower latency, faster content delivery and better compliance with data sovereignty laws.

By stepping outside Lagos, Nugi is making a political statement as much as a technical one — cloud access should not be a Lagos privilege.

Running office workloads on renewables is one thing. Running AI inference clusters, render farms and crypto GPUs is another. These use constant high loads, prone to sudden spikes that solar and hydropower alone cannot always absorb.

Both Botswana and Nigeria have quietly solved that question the same way: hybrid energy models.

Neither is claiming to run fully on clean energy. Instead they are saying renewables first, natural gas when necessary. That may not satisfy purists but it answers the biggest fear of any hyperscaler — power interruptions.

Nairobi and Cape Town already host heavyweight facilities from players like Airtel, Africa Data Centres, and Google. Airtel’s new 44MW hyperscale build at Tatu City is proof that Kenya can support Tier IV ambitions.

But the next big land grab might not unfold inside major capitals. Instead, hyperscalers are now chasing locations where power is cheaper, land is abundant, and political red tape is thinner — places like Palapye in Botswana or Calabar in Nigeria.

These projects are not about building colo space. They are about locking in strategic relevance.

If Botswana becomes the cheapest place to run GPUs, it becomes a leverage point in global AI supply chains. If Nigeria localises cloud for its regions, it becomes the default host for West African fintech, streaming and health records.

The data centre is no longer just a building. It is a sovereignty tool.

Africa’s digital future will not be written in boardrooms or parliaments. It will be written where solar panels meet server racks, where dams feed transformers, and where rural land becomes the new real estate of computation.

Botswana and Nigeria are first to plant their flags. Others will follow.
