For years, the story of Africa's digital economy was told mostly through smartphones and mobile money. In 2025, a quieter but far more consequential chapter opened: the race to build the physical infrastructure — the data centres — that will decide whose economy gets to participate in the cloud and AI era, and whose does not.
As of November 2025, Tanzania hosts 11 operational data centres, placing it 6th on the continent — ahead of Mauritius, Ghana, Angola, and Senegal, and within striking distance of Morocco. Most of that capacity is concentrated in Dar es Salaam, with additional facilities in Arusha and Dodoma, tied into the SEACOM and EASSy submarine cable systems.
It is a genuine achievement. It is also a fragile position. The real question is not the ranking — it is what Tanzania does with it next.
Figure 1 & 2 — Africa's Data-Centre League Table, November 2025.
The middle of the table tells a more interesting story. Nigeria (21), Kenya (20), Egypt (13) and Morocco (12) are the fastest-expanding mid-tier markets. Each is anchored by a different strategic asset: Nigeria by the sheer scale of its consumer and fintech market, Kenya by cheap geothermal power from Olkaria, Egypt by submarine-cable landings on the Mediterranean, and Morocco by its role as Europe's nearest digital neighbour.
Tanzania, Mauritius, Ghana, Angola and Senegal then round out the top 10, each with between seven and eleven facilities.
Fig 3 - Africa's position in the global data-centre market.
Other headline numbers from the ADCA report:
230 data centres spread across 38 African countries
Market projected to reach $9.2 billion by 2029
Installed capacity expected to triple to ~1.2 GW by 2030
More than 95% of global internet traffic already runs through data centres
The gap is enormous — but so is the opportunity. ADCA, the African Energy Chamber, and development finance institutions including the IFC, DFC, BII and Proparco are all now treating data centres as strategic infrastructure on a par with ports, power grids and fibre networks. Global hyperscalers like Microsoft, Google, Oracle and Amazon are shifting from leasing distant capacity to co-developing facilities on African soil.
The concern is a familiar one: most of the data generated in Africa still gets processed and stored abroad — primarily in Europe and North America — leaving African economies in what ADCA bluntly describes as an extractive model: raw data flows out, high-value digital services flow back in, and the margin sits offshore.
Figure 4 — The three forces shaping Africa's data boom: power, latency, and sovereignty.
Modern AI-ready racks demand 30 kW to 120 kW each — up to ten times the load of a traditional server rack. A single hyperscale facility can require 100 MW just to get started; Kenya's president William Ruto noted recently that the proposed Microsoft–G42 campus would, at full scale, consume over 40% of his country's total grid capacity.
Tanzania's hydro expansion (Julius Nyerere Hydropower Project) and its growing natural-gas generation give it a real card to play here — but only if large industrial customers like data centres can access that power predictably and affordably through transparent Power Purchase Agreements.
For basic websites, offshore hosting is tolerable. For real-time AI inference — the part of AI that actually answers user queries — it is not. This is why content providers and AI companies are now racing to move inference workloads physically closer to end users. Countries that have in-country compute capacity will capture those workloads. Countries that do not will keep exporting raw data and importing finished intelligence.
Investors increasingly see clear local data-protection rules not as red tape, but as a demand signal: they create predictable, bankable in-country workloads. Countries with vague or unenforced frameworks lose out not because they regulate too much, but because they regulate unpredictably.
Tanzania's own Personal Data Protection Act (2022) and Personal Data Protection Commission already put the country ahead of several neighbours on paper. The test is enforcement capacity and regulatory clarity — the two things investors actually price in.
A single 40 MW data centre, with a 15-year Power Purchase Agreement signed by a creditworthy hyperscaler, provides the kind of predictable offtake that lets independent power producers raise billions in construction finance. The power plant gets built. The data centre gets its electricity. And the spillover capacity lights up factories, agro-processing plants and homes that would otherwise wait years for grid expansion.
This reverses the traditional development sequence. It also means that a country like Tanzania, with substantial untapped hydro and gas resources, can use data-centre demand as a lever to accelerate its overall energy build-out — rather than waiting for the grid to mature before the digital economy can scale.
Whether large-scale Tier III/IV facilities are commissioned in Dodoma or along the Dar es Salaam–Bagamoyo corridor, closer to new energy and port infrastructure
Whether the regulatory framework around cross-border data flows becomes clearer, particularly for regional EAC integration
Whether Tanzanian universities and TVET institutions begin producing the specialist technicians the sector needs — the ADCA Data Centre Talent Project for Africa, launched in mid-2025, is piloting in Nigeria, Kenya and South Africa first, and Tanzania would benefit from joining the second wave
Whether the government explicitly designates data centres as strategic industrial infrastructure eligible for priority power access and tax treatment, as Kenya and Morocco have done
Tanzania is on the list. The harder — and more interesting — work begins now.

The league table: South Africa far out in front
South Africa sits alone at the top with 56 verified operational facilities — more than the next three countries (Nigeria, Kenya, Egypt) combined. Johannesburg and Cape Town host hyperscale campuses from Teraco, Africa Data Centres, NTT and Vantage, plus cloud regions from AWS, Microsoft Azure and Google Cloud.The middle of the table tells a more interesting story. Nigeria (21), Kenya (20), Egypt (13) and Morocco (12) are the fastest-expanding mid-tier markets.

Tanzania, Mauritius, Ghana, Angola and Senegal then round out the top 10, each with between seven and eleven facilities.
The bigger picture: Africa still holds less than 1% of global capacity
Zoom out, and the picture becomes sobering. According to the Africa Data Centres Association's 2026 Economic Report, the entire continent accounts for roughly 0.6% of global data-centre capacity. The United States alone holds about 45%.Fig 3 - Africa's position in the global data-centre market.

Why this matters for Tanzania specifically
Being on the list is one thing. Capturing its economic value is another. The ADCA report identifies three forces that will determine which African countries genuinely move up the digital value chain, and which simply host buildings:Figure 4 — The three forces shaping Africa's data boom: power, latency, and sovereignty.
1. Power is the real bottleneck
Connectivity can be solved with cables. Power cannot be faked. Africa's average Power Usage Effectiveness (PUE) — a measure of how efficiently electricity is converted into useful compute — sits at 1.67, compared to a global benchmark of 1.58. Transmission and distribution losses in parts of East and West Africa are as high as 18–25%, against a global average of 7–8%.Modern AI-ready racks demand 30 kW to 120 kW each — up to ten times the load of a traditional server rack. A single hyperscale facility can require 100 MW just to get started; Kenya's president William Ruto noted recently that the proposed Microsoft–G42 campus would, at full scale, consume over 40% of his country's total grid capacity.
Tanzania's hydro expansion (Julius Nyerere Hydropower Project) and its growing natural-gas generation give it a real card to play here — but only if large industrial customers like data centres can access that power predictably and affordably through transparent Power Purchase Agreements.
2. Latency decides who gets the AI workloads
When Tanzanian data is processed in Frankfurt or Amsterdam, round-trip latency typically runs 70 to 100 milliseconds. In mature markets with local infrastructure, it is under 20 ms. Research cited in the ADCA report indicates that once latency crosses roughly 40–50 ms, user experience starts to degrade visibly — video calls stutter, AI assistants feel slow, trading platforms misprice, cloud applications freeze.For basic websites, offshore hosting is tolerable. For real-time AI inference — the part of AI that actually answers user queries — it is not. This is why content providers and AI companies are now racing to move inference workloads physically closer to end users. Countries that have in-country compute capacity will capture those workloads. Countries that do not will keep exporting raw data and importing finished intelligence.
3. Sovereignty has moved from slogan to investment signal
More than 40 African countries have now enacted data-protection laws. 19 countries have ratified the Malabo Convention. In April 2025, the Africa Declaration on Artificial Intelligence, adopted in Kigali, committed $60 billion to the Africa AI Fund — a blended-finance vehicle designed to catalyse continental AI infrastructure.Investors increasingly see clear local data-protection rules not as red tape, but as a demand signal: they create predictable, bankable in-country workloads. Countries with vague or unenforced frameworks lose out not because they regulate too much, but because they regulate unpredictably.
Tanzania's own Personal Data Protection Act (2022) and Personal Data Protection Commission already put the country ahead of several neighbours on paper. The test is enforcement capacity and regulatory clarity — the two things investors actually price in.
The new economic logic: data centres as anchor tenants
Perhaps the most important shift buried in the ADCA report is this: data centres are no longer just consumers of power and fibre. They are increasingly becoming the anchor tenants that make large energy projects financially viable in the first place.A single 40 MW data centre, with a 15-year Power Purchase Agreement signed by a creditworthy hyperscaler, provides the kind of predictable offtake that lets independent power producers raise billions in construction finance. The power plant gets built. The data centre gets its electricity. And the spillover capacity lights up factories, agro-processing plants and homes that would otherwise wait years for grid expansion.
This reverses the traditional development sequence. It also means that a country like Tanzania, with substantial untapped hydro and gas resources, can use data-centre demand as a lever to accelerate its overall energy build-out — rather than waiting for the grid to mature before the digital economy can scale.
What to watch over the next 24 months
Several specific inflection points will tell us whether Tanzania consolidates its position or slips back:Whether large-scale Tier III/IV facilities are commissioned in Dodoma or along the Dar es Salaam–Bagamoyo corridor, closer to new energy and port infrastructure
Whether the regulatory framework around cross-border data flows becomes clearer, particularly for regional EAC integration
Whether Tanzanian universities and TVET institutions begin producing the specialist technicians the sector needs — the ADCA Data Centre Talent Project for Africa, launched in mid-2025, is piloting in Nigeria, Kenya and South Africa first, and Tanzania would benefit from joining the second wave
Whether the government explicitly designates data centres as strategic industrial infrastructure eligible for priority power access and tax treatment, as Kenya and Morocco have done
The bottom line
Africa's data-centre market is no longer a niche or a pipeline story. It is a live, multi-billion-dollar build-out, and the geography of it is being locked in now. The countries that secure anchor investments in the next 24–36 months will shape where the continent's AI, fintech and cloud economy actually lives for the next two decades.Tanzania is on the list. The harder — and more interesting — work begins now.
