• Africa's digital infrastructure push now confronts the same constraint that has held back industrial growth for decades
  • Reliable power is becoming a decisive competitive advantage for digital infrastructure across African markets


The fact

Africa's growing digital ambitions are running into a familiar constraint: electricity. As data centres, fibre networks and cloud services expand across the continent, the quality and reliability of power supply is emerging as the main bottleneck. New subsea cables are improving international connectivity, but domestic grids remain fragmented and uneven, particularly in markets where demand is growing fastest.

Tower operator Helios Towers is expanding solar and battery hybrid power systems across its sites to reduce reliance on diesel generators. In Kenya, state utility KenGen and transmission operator KETRACO have been exploring partnerships with digital infrastructure stakeholders. Lagos, Nairobi and Johannesburg are seeing rapid data centre expansion, yet ageing grid infrastructure and lengthy grid-connection processes continue to delay deployments.

Industry observers note that Africa's next digital phase will depend on solving the energy problem. Governments, utilities and private investors are all being drawn into a challenge that is no longer just about laying cables but about building the power systems that keep them operational.

The assessment

Africa has made significant progress in expanding digital connectivity through new fibre networks and subsea cables. The next challenge is ensuring there is enough reliable electricity to support the infrastructure those networks enable. As AI and cloud services increase computing demand, power systems are becoming as important as connectivity itself.

This is changing how investors assess opportunities across the continent. Markets that combine dependable power, modern transmission networks and predictable regulation are likely to attract the largest share of long-term investment.

For BTW readers, energy and digital infrastructure policy is converging into a single competitive factor. Governments that strengthen both systems together will be better positioned to attract hyperscalers and cloud capital. Africa's next digital phase depends on powering the infrastructure that supports it.

What to watch

Watch whether other African data centre operators follow Helios Towers in adopting solar and battery hybrid systems to reduce diesel dependency. Also monitor whether governments introduce coordinated energy and digital infrastructure policies rather than treating them as separate sectors. The pace of grid modernisation and renewable energy investment will be a leading indicator of which markets attract the largest share of hyperscale and cloud capital.
