Most conversations about Africa’s digital infrastructure centre on the same story: too few subsea cables, too little fibre inland, and data that travels too far before it becomes useful. Edge computing does not solve that story so much as work around it. Instead of routing every request to a distant hyperscale data centre, it processes data closer to where it is generated, at a cell tower, a regional facility, or a device itself. For a continent where connectivity is real but uneven, that difference in geography is starting to matter commercially.

A Market Growing Faster Than the Headlines Suggest

Africa’s data centre construction sector was valued at $1.26 billion in 2024 and is projected to reach $3.06 billion by 2030, according to Introl. Edge capacity specifically is expected to climb from roughly 0.4 gigawatts today to between 1.5 and 2.2 gigawatts by 2030, growing at more than 14 percent annually, with South Africa, Nigeria, Kenya and Egypt as the leading hubs, per Engineering News. That growth is not evenly spread. South Africa currently hosts 97 percent of identified edge facilities on the continent, according to the Africa Interconnection Report 2025, meaning the rest of the continent is still catching up from a low base.

Nigeria’s build-out illustrates the pace of that catch-up. Open Access Data Centres, owned by wholesale operator WIOCC, already runs six hyperscale facilities and more than thirty edge sites across South Africa, the DRC and Nigeria, and is reportedly planning a $240 million, 24-megawatt facility in Lagos, according to Data Center Dynamics. Airtel is building what is set to be Nigeria’s largest data centre, while smaller entrants such as Fringe Africa are targeting regional cities rather than just Lagos and Abuja, per a survey by Technext24.
