Africa Urged to Shift From Megawatt Thinking to Gigawatt Ambitions as AI Power Demand Surges
Africa risks falling behind in the rapidly expanding artificial intelligence economy unless governments and energy planners begin developing power infrastructure at gigawatt scale rather than relying on smaller, incremental energy projects, according to industry leaders ahead of African Energy Week 2026.
The warning comes as global AI growth fuels an unprecedented rise in electricity demand from hyperscale data centres, many of which now require power capacity far beyond the levels traditionally associated with digital infrastructure.
Industry analysts say the explosive growth of AI applications is reshaping global energy planning, with large-scale data campuses increasingly consuming hundreds of megawatts individually and, in some cases, pushing total demand into the gigawatt range.
For Africa, the challenge is particularly significant. Although the continent possesses vast untapped energy resources, much of its electricity planning still centres on gradual megawatt-scale expansion designed to address local shortages or near-term demand increases.
Experts argue that this approach is no longer sufficient in an AI-driven global economy.
Africa’s data centre industry remains relatively small compared with major global markets, with operational capacity currently estimated at between 300 MW and 400 MW. However, forecasts suggest the sector could expand to between 1.5 GW and 2.2 GW by 2030 as cloud computing, AI processing and digital services accelerate across the continent.
At the same time, electricity consumption linked to data centres is rising by an estimated 20% to 25% annually, with overall demand expected to reach around 8,000 GWh in the near future.
Globally, data centre energy consumption is projected to approach 945 TWh by 2030, largely driven by AI workloads that require vast computing power and uninterrupted energy supplies.
Unlike many conventional industrial facilities, AI-focused data centres demand highly stable electricity systems with built-in redundancy and long-term scalability. This is forcing governments and utilities worldwide to rethink traditional energy planning strategies.
Industry observers say Africa will need to adopt a more integrated approach that combines large-scale power generation, transmission infrastructure and digital economy development if it hopes to attract significant AI and cloud investment.
The report also suggests that surplus energy capacity – traditionally viewed by many African utilities as financially inefficient – may become increasingly important in supporting future digital infrastructure. Maintaining reserve capacity could improve grid stability while providing flexibility for rapid growth in electricity demand.
Northern Virginia in the United States, currently the world’s largest data centre market, is being highlighted as an example of how quickly demand can escalate. Installed capacity there has surpassed 4 GW, with more than 1 GW of additional supply delivered in a single year as major technology companies race to expand AI capabilities.
These issues are expected to feature prominently during the AI and Data Center Track at African Energy Week 2026, where policymakers, infrastructure developers and energy leaders will examine how Africa can position itself within the next phase of the global digital economy.
“This is ultimately about aligning Africa’s energy strategy with where global demand is heading,” said NJ Ayuk.
“If we continue to plan in megawatts, we will struggle to compete in an economy that is already moving at the gigawatt scale. Building larger, more resilient power systems is not just about meeting demand – it is about creating the conditions for investment, innovation and long-term growth.”
