Africa’s data centre boom is creating something the power sector has struggled to find for decades: large, predictable, long-term electricity demand. The continent’s data centre construction market is projected to grow from US$1.24 billion in 2025 to US$4.58 billion by 2031, expanding at more than 24% annually. That growth is not being driven by technology alone. It is being driven by infrastructure. Every new facility requires reliable electricity, cooling systems, backup generation, fibre connectivity, and land.
Unlike factories or commercial buildings, data centres consume power continuously. A hyperscale facility can require tens of megawatts of uninterrupted electricity every hour of every day. Reliability matters just as much as price because even a brief outage can disrupt banking platforms, cloud services, telecommunications, and government systems.
South Africa remains the continent’s largest market, accounting for more than half of Africa’s operational data centre capacity, while Kenya and Nigeria are rapidly expanding as digital demand increases. Global cloud providers and colocation companies are investing alongside local developers to meet growing demand from financial services, telecoms, e-commerce, and artificial intelligence.

The implication extends beyond the digital economy. Every new data centre becomes a long-term electricity customer. That creates opportunities for utilities, independent power producers, renewable energy developers, battery storage providers, and transmission companies. In many cases, dedicated solar plants, battery systems, or private power purchase agreements are becoming part of the project from the outset rather than an afterthought.
For governments, attracting data centres is increasingly tied to energy policy. Countries that can provide reliable power, clear regulation, and modern digital infrastructure will be better positioned to attract billions of dollars in technology investment. Those that cannot will struggle to compete, regardless of their internet penetration or digital ambitions.
The next phase of Africa’s digital economy will not be determined by software alone. It will depend on whether countries can build the energy systems capable of powering it.
