  • Mombasa’s $1.5B Floating Data Centre Bets on Off-Grid Power

    Mombasa’s $1.5B Floating Data Centre Bets on Off-Grid Power

    TL;DR · 30-second read

    The Short Version

    A Greek energy company and an American turbine maker want to build a $1.5 billion artificial intelligence data centre at the port of Mombasa, Kenya.

    The unusual part: it would generate its own electricity on a barge floating in the harbour, burning imported natural gas, and never plug into Kenya’s national power network at all. That sidesteps blackouts and the long wait to get connected.

    If it is approved and built, East Africa would gain the kind of heavy computing power that today sits mostly in Europe and America. Kenyan regulators have not yet said yes.

    Construction Review reported that Greek multinational Amaco Energy Group has partnered with US energy equipment and services company GE Vernova on Project HERCULES, a proposed $1.5 billion (roughly KSh 194.2 billion) artificial intelligence data centre at the Port of Mombasa, Kenya. Under the arrangement, GE Vernova gas turbines would be integrated into an Amaco power barge, an unmotorised floating platform housing a power plant, that supplies the campus with electricity and cooling.

    The facility is designed to run entirely off-grid on offshore liquefied natural gas, with power scalable from an initial 60 to 100 megawatts up to 1,000 megawatts, and with the option to export surplus electricity to Kenya’s national network near the Mariakani substation. The project sits in the Port of Mombasa and Dongo Kundu ecosystem, is listed as proposed and pending regulatory approval, and is estimated to take about 28 months to build once approved.

    Executive Summary

    Project HERCULES is best understood not as a data centre that happens to have a power plant, but as a power project that has found a customer. The blueprint evolved from an earlier liquefied natural gas-to-power transmission proposal registered in 2024. In its current form, the generation, the cooling and the compute halls are bundled into a single floating architecture moored inside the port, with GE Vernova supplying the turbines and electrification equipment.

    That structure is a direct answer to the constraint that has slowed large computing campuses across much of Africa. Land is available, subsea fibre has landed, and capital is willing. What is scarce is firm, reliable power delivered on a developer’s schedule rather than a utility’s. By declining to connect at all, Amaco converts a multi-year grid question into a procurement and permitting question it can largely control.

    The trade is real but not free. An off-grid campus becomes its own utility: it carries fuel price exposure, it must build its own redundancy because there is no network to fall back on, and it must satisfy Kenyan energy, environmental and port regulators before any of it exists. Nothing has been approved, no customer has been named, and the financing behind the headline number has not been described.

    When the Grid Is the Bottleneck, Bring Your Own

    In mature markets, the queue to connect a large electrical load to the national network, known in the industry as the interconnection queue, has become the single longest item on a data centre schedule. In much of sub-Saharan Africa the problem takes a different shape: the wait can be shorter, but the delivered power is less firm, and a campus full of high-density servers cannot absorb unplanned outages. The Amaco framing is explicit on this point. Bypassing the grid, it argues, removes downtime tied to supply shortages rather than merely hedging against it.

    Inverting the sequence has a commercial logic that goes beyond reliability. A developer who owns generation can commit to an energisation date, and an energisation date is what an anchor tenant is actually buying. The cost is that the developer becomes a power company. Fuel must be contracted and shipped, turbines must be maintained, and the redundancy that a utility connection normally provides has to be built into the platform itself. A campus that is genuinely 100 percent islanded has no external backstop, so its reserve margin is a design choice with a capital cost attached.

    The Barge Is the Product

    An unmotorised power barge is built in a shipyard and towed to its mooring. That matters more than it sounds. Shipyard fabrication trades unpredictable on-site civil works for a controlled construction environment, which is one plausible route to the stated 28-month build. It also makes the asset relocatable in principle, and it places the plant on water, which simplifies the heat rejection problem that dominates dense computing. The release describes direct cooling integrated into the same floating structure, though the specific method is not detailed.

    The capacity range published for the project spans from an initial 60 to 100 megawatts to an eventual 1,000 megawatts. That is more than a tenfold spread, and it should be read as a statement of modular ambition rather than a committed build. The $1.5 billion valuation is not tied in the announcement to any particular point on that range. Anyone sizing the opportunity, whether a lender, a turbine supplier or a prospective tenant, needs to know which phase the figure buys, because the answer determines whether this is a large regional facility or the first slice of something hyperscale.

    Landing Where the Cables Land

    Mombasa’s strategic case rests on geography. It is East Africa’s principal arrival point for international subsea fibre-optic cables, the undersea trunk lines that carry almost all intercontinental internet traffic. Putting compute next to a cable landing station shortens the path between regional users and the machines serving them, and it makes local data residency possible for customers whose regulators or contracts require it. The project also targets industrial synergy with the neighbouring ARISE Coast Integrated Industrial Park inside the 3,000-acre Dongo Kundu Special Economic Zone, which offers a second class of power offtake alongside the servers.

    The demand question is more nuanced than the connectivity story suggests. Large-scale artificial intelligence training is relatively indifferent to latency and gravitates to wherever power is cheapest. What benefits from proximity is inference, the stage where a trained model actually answers queries, along with sovereign and enterprise hosting for governments, banks and telecom operators that want their data inside national borders. Those are credible markets, but they are being contested. The announcement itself notes that other countries, Ethiopia among them, are pursuing the same regional hub position.

    Who Gains, and What Has to Be True

    For GE Vernova, spun out of General Electric in 2024, the appeal is straightforward. Gas turbines have become one of the few technologies that can add firm generation at computing-campus timescales, and a floating deployment extends that market to places where onshore siting is difficult. For Amaco, the repositioning is the more interesting move: a gas-to-power scheme from 2024 has been recast with artificial intelligence demand as its anchor load, which is a considerably more bankable story than selling electrons into a constrained transmission system. The proposed surplus export near the Mariakani substation adds a second revenue line and, just as usefully, gives Kenyan authorities a reason to see the project as a contributor rather than an enclave.

    Three conditions have to hold. Imported liquefied natural gas must be priced competitively enough that the campus can quote power rates a regional customer will accept, since fuel, not hardware, dominates the operating cost of a gas-fired site. Regulatory approval must cover energy licensing, environmental consent and port anchoring rights simultaneously, and the announcement places the project firmly at the discussion stage with Kenyan authorities and financiers. And the stated future conversion to hydrogen should be treated as design optionality rather than a near-term plan, because it depends on a fuel supply chain that does not yet exist at this scale anywhere.

    Background

    Amaco Energy Group is a Greek multinational energy firm. Its Mombasa plan did not begin as a computing project: the blueprint evolved from an earlier liquefied natural gas-to-power transmission proposal registered in 2024, since recast around artificial intelligence demand as the anchor load. GE Vernova is the energy equipment and services company spun out of General Electric in 2024, whose gas turbine business has become central to a global race to add firm generation quickly enough for data centre construction schedules.

    Kenya has spent a decade positioning itself as East Africa’s digital gateway, and Mombasa is the physical hinge of that claim because the region’s international subsea fibre-optic cables come ashore there. The country is also building out the Dongo Kundu Special Economic Zone, a 3,000-acre industrial area near the port overseen in part through the Kenya Ports Authority. Competition for the regional hub position is active, with Ethiopia among the countries pursuing similar ambitions.

  • Digital Realty Opens 6.4 MW Nairobi Two Interconnection Hub

    Digital Realty Opens 6.4 MW Nairobi Two Interconnection Hub

    TL;DR · 30-second read

    The Short Version

    Digital Realty, a global company that builds the warehouses full of computers that run the internet, has opened its second data center in Nairobi, Kenya.

    The interesting part is not its size — it is small — but who is already inside: more than 100 phone and internet carriers that customers can plug straight into, plus a dish link to satellites for places cables do not reach.

    For Kenyan businesses, that means their data can stay in the country and still reach the rest of the world quickly.

    Digital Realty (NYSE: DLR) announced on September 7 that it has opened Nairobi Two (NBO2), a 6.4-megawatt data center built alongside its existing Nairobi One (NBO1) facility, expanding the company’s Nairobi campus. According to the company’s announcement, customers on the campus can connect to more than 100 networks, two internet exchange points and a satellite teleport — a ground station that routes traffic via satellite where terrestrial fibre is limited.

    The opening coincides with iColo, Digital Realty’s East African operation, transitioning to the Digital Realty brand in Kenya and Mozambique and folding its local ecosystem into PlatformDIGITAL, the company’s global data center platform. Digital Realty describes its footprint as more than 300 facilities across 55-plus metros in over 30 countries.

    Executive Summary

    The headline number — 6.4 megawatts, a measure of the electrical capacity available to customers’ servers — is modest by the standards of Digital Realty’s recent announcements elsewhere. What is being sold in Nairobi is not raw scale but adjacency: the ability to sit in the same building as more than 100 carriers, two internet exchange points and a satellite uplink, and to reach any of them with a short cable rather than a long-haul circuit.

    That distinction matters commercially. In colocation, an operator rents space, power and cooling; in interconnection, it monetises the density of parties already present. Interconnection revenue tends to carry higher margins and stickier tenancy, because moving out means severing every connection a customer has built. Nairobi Two extends a campus where that density already exists rather than starting one from scratch.

    The simultaneous rebranding of iColo in Kenya and Mozambique is the second half of the story. It converts a respected regional operator into a node on a global platform, which changes how multinational buyers can contract for African capacity — and raises questions, so far unanswered publicly, about pricing, contracted capacity and how much further the company intends to build on the continent.

    Interconnection, Not Megawatts, Is the Product Here

    A useful way to read any data center announcement is to ask what the operator is actually selling. Some facilities sell power and floor space at scale, aimed at customers who need very large blocks of compute. Others sell proximity to networks. Nairobi Two is plainly the second kind. Digital Realty leads with 100-plus networks, two internet exchange points — neutral switching platforms where networks swap traffic directly instead of paying transit providers to carry it — and a satellite teleport, and treats the 6.4 MW as supporting detail.

    The economics behind that emphasis are well understood in the industry. A carrier-neutral campus, meaning one that favours no single telecom provider, becomes more valuable to each tenant as more tenants arrive: content providers want to be near eyeball networks, banks want to be near clouds, carriers want to be near both. Once a customer has provisioned dozens of cross-connects, the switching cost of leaving is high. Interconnection density is, in effect, a moat built by other people’s cabling.

    For Kenyan and regional enterprises, the practical benefit is latency and cost. Traffic that can be exchanged locally does not have to transit Europe and back, which shortens round trips and reduces international bandwidth spend. That is a real operational improvement, and it is the most substantiated claim in the announcement — the ecosystem figures are specific and verifiable by any prospective customer touring the site.

    What the iColo Rebrand Buys, and What It Costs

    Folding iColo’s Kenyan and Mozambican sites into the Digital Realty brand and PlatformDIGITAL is more than signage. For a multinational evaluating African capacity, a global brand means a single master agreement, familiar service-level terms, consistent operational standards and access through a sales channel that already serves the customer elsewhere. That materially lowers the procurement friction that has historically slowed enterprise commitments in frontier markets.

    Wanja Muriithi, Digital Realty’s Country General Manager for Kenya, framed the opening and the rebrand as “one story” — local ecosystem plus global platform. Marcel Louw, Managing Director for Africa, positioned the campus as a gateway for customers serving Kenya, Africa or global markets. Both framings are consistent with how platform operators typically integrate regional acquisitions, and neither is quantified in the announcement.

    There is a trade-off worth naming without overstating it. Regional operators often win on price flexibility, local relationships and responsiveness to smaller customers; global platforms standardise, which can be a benefit or a constraint depending on the tenant. Whether existing iColo customers see changed commercial terms is not addressed in the announcement, and it is a fair question for buyers to put to the company directly at renewal.

    Sovereignty and the Case for a Satellite Route

    Digital Realty cites data sovereignty — the requirement, whether legal or contractual, that certain data physically remain within a country’s borders — as one of the forces reshaping infrastructure decisions in East Africa. That demand driver is credible and increasingly common globally: regulated sectors such as banking, health and government are usually the first movers, because their supervisors write the rules. Local capacity paired with dense interconnection is precisely the configuration that lets an organisation keep data in-country while still reaching global cloud platforms.

    The satellite teleport is the less conventional element and deserves a plain explanation. It is a ground facility that sends and receives traffic via satellite, offering a path to locations where terrestrial fibre is sparse, and an alternative route when a terrestrial or subsea path is unavailable. In a region where long-haul connectivity concentrates on a limited number of physical routes, having a diverse path inside the same interconnection campus is a genuine resilience feature rather than a marketing flourish — though its usefulness depends on capacity and cost, neither of which the company has disclosed.

    Does 6.4 MW Answer the AI Capacity Question?

    The stated editorial question — whether African markets can support AI-era capacity — is not settled by this facility, and the announcement does not claim it is. Training large models is a power problem measured in tens to hundreds of megawatts, with rack densities that typically require liquid cooling. Digital Realty’s own recent announcements show where that class of capital is going: the company said in August it had been selected to develop 50 megawatts in Singapore, roughly eight times the capacity of Nairobi Two, and broke ground on a facility in Switzerland.

    The more plausible near-term African AI story is inference and delivery rather than training: running already-trained models close to users, serving content locally, and keeping the resulting data resident. That workload profile is far better matched to a dense interconnection campus of this size than to a hyperscale training campus, and building in increments of a few megawatts is a defensible way to follow demand rather than front-run it — capital discipline, not timidity.

    The constraint to watch is power. Interconnection density can be assembled through commercial relationships; grid capacity, reliability and cost cannot. Any credible expansion of this campus toward AI-relevant scale would require the company to speak publicly about power procurement, cooling design and rack density, none of which appears in this announcement. Until it does, Nairobi Two is best read as a well-targeted connectivity asset — a gateway play — rather than evidence that the region is ready for AI-era compute at scale.

    Background

    Digital Realty is a US-listed real estate investment trust (NYSE: DLR) that owns and operates data centers globally, describing itself as the world’s largest cloud- and carrier-neutral data center platform with more than 300 facilities in over 55 metros across 30-plus countries on six continents. Its business combines colocation — renting secure, powered, cooled space for customers’ servers — with interconnection, the higher-margin business of enabling customers to connect directly to the carriers, clouds and content providers sharing the building.

    Nairobi has developed as one of East Africa’s principal digital infrastructure markets, and Digital Realty’s campus there operates through iColo, the East African business now taking the Digital Realty brand in Kenya and Mozambique. The campus already housed Nairobi One before this week’s addition of Nairobi Two. The company’s wider 2026 activity has included being selected to develop 50 megawatts in Singapore in August, a groundbreaking in Switzerland, and leadership appointments across regional markets including Iberia.
