A senior African energy executive has signalled that the expansion of data centre capacity across the continent could play an important role in modernising its electricity infrastructure, tackling persistent shortages while unlocking digital growth opportunities. 

According to “The State of African Energy: 2026 Outlook Report” published by the African Energy Chamber (AEC), the number of data facilities in Africa is increasing, but the continent still hosts only 223 sites across 38 countries, or just a tiny fraction of the global total. South Africa leads with 56 data hubs, followed by Kenya with 19 and Nigeria with 17. 

The report highlights how demand for digital services, from mobile web browsing to cloud computing, is driving growth in data centre activity, with the African market valued at about US$3.49 billion in 2024 and forecast to reach US$6.81 billion by 2030.

Data centre electricity demand capacity is also expected to rise to around 2 GW by 2030, reflecting expanding computing needs. 

However, the report notes that many operators still struggle with unreliable national grids, forcing them to depend on expensive diesel generators and pushing up both costs and emissions.

Nigeria’s grid, for example, supplies only a few hours of electricity per day in many areas, presenting a significant hurdle for data facilities that require constant power. 

The AEC suggests that investment in data centres could attract socially responsible capital into the energy sector, incentivising upgrades to power generation and grid systems.

As these facilities grow, they are also prompting demand for innovative energy solutions, such as renewable sources and enhanced grid management technologies, which could in turn improve electricity reliability for other consumers. 

This view is echoed by industry commentary pointing out that the predictable energy needs of data hubs make them attractive to investors seeking long-term returns, and that their growth encourages the deployment of cleaner energy and smarter grid technologies.

Some nations are already tapping into green energy, with projects such as solar farms and geothermal-backed centres aiming to reduce dependence on fossil fuels. 

In a blog post written by NJ Ayuk, executive chairman, African Energy Chamber, he cautions that without strong policy frameworks, energy investments tied to digital infrastructure risk benefiting only urban and commercial sectors rather than extending electricity access more widely.

Nonetheless, proponents argue that data centres can serve both economic and energy development goals if energy planning includes provisions to integrate new capacity with national electrification programmes.
