The Short Version
A global operator of data centers, the warehouses of computers behind the internet, plans to generate its own electricity on site at multiple new projects rather than rely mainly on the public power grid.
NTT DATA will use fuel cells from Bloom Energy, machines that make electricity without burning fuel. The total is about what one large power plant produces, with deliveries starting in 2027.
The reason is artificial intelligence: demand can outrun what the grid supplies. The open question is now whether Bloom can build and install the machines fast enough.
Data Centre Magazine reported on November 6, 2026 that NTT DATA has signed an agreement with Bloom Energy to deploy 900 megawatts (MW) of onsite power generation across multiple data center projects worldwide. NTT Global Data Centers will use Bloom’s fuel cells as the primary power source for the sites covered, with initial shipments due to begin in 2027.
Bloom describes the agreement as its largest international project to date. The two companies say the relationship is designed to expand across NTT Global Data Centers’ portfolio and reach gigawatt scale.
Executive Summary
NTT DATA’s agreement with Bloom Energy puts fuel cells, which generate electricity through a non-combustion process, at the center of the power plan for multiple data center projects. The stated goal is speed: bringing capacity online faster in markets where grid power is constrained, as clients build AI capacity.
The most significant word in the announcement is “primary.” Onsite generation used as backup supports a site that still depends on the grid. Onsite generation used as primary supply makes the equipment supplier central to when a site can open and start earning revenue.
That is the trade at the heart of the deal. NTT reduces its exposure to grid timelines at these sites and takes on greater exposure to how quickly Bloom can manufacture, ship and install 900MW of equipment, starting in 2027. Whether the exchange pays off will depend on terms and site-level schedules that remain to be tested.
The Grid Wait Becomes a Delivery Schedule
A data center cannot earn revenue until it has power, and in constrained markets the utility’s timeline can become the item on a project’s critical path, the chain of tasks that sets the earliest possible finish date. Doug Adams, CEO of NTT Global Data Centers, framed the deal in those terms: clients are building AI capabilities “at a pace the grid alone cannot always match.” Making fuel cells the primary supply changes what sits on that path. At the covered sites, the power date depends less on a utility connection and more on when Bloom ships, when crews install and when the units are ready to run.
Bloom’s modular design softens part of that exposure. Capacity can be added in phases, so a late shipment might delay one block of a campus rather than all of it. The same design also turns one large dependency into many smaller ones, because each phase has to line up with construction. Adams’s description of bringing capacity online “alongside construction” captures the requirement. With initial shipments due in 2027, the agreement also sets a practical starting point, and NTT’s plan to invest more than $10 billion in AI-ready infrastructure runs through that same year.
The people affected are easy to identify. NTT’s clients care about the date capacity arrives, NTT’s revenue timing follows that date, and Bloom now carries a highly visible execution burden. This is a shift in operational dependency, not necessarily in financial liability, since who pays for a late shipment is a matter of contract. A manufactured product may well prove faster than a grid upgrade. The measure of the advantage will be the months saved at a given site, which is the number that would turn speed to power from a principle into a quantifiable benefit.
Primary Power Is a Bigger Claim Than Backup Power
Describing fuel cells as primary power moves them well beyond an emergency role, and that supports reading the deal as more than a short-term patch. Still, “primary” does not settle how long that role lasts. Fuel cells could remain the main source for a site’s full life, or they could carry the load until grid capacity arrives and then take a smaller role. Those are very different business cases for both companies, with different implications for equipment life, operating cost and long-term fuel needs.
Scale gives a useful sense of the commitment. The 900MW figure is nearly eight times the almost 115MW of new US capacity commitments NTT announced in March 2026, although generation capacity and data center commitments are not identical measures and the comparison is only a guide to size. The gigawatt ambition deserves a more measured reading. Taken literally, one gigawatt is only about 100MW above the 900MW already announced, so the more meaningful test of the “model” Bloom’s Aman Joshi describes is whether it spreads across NTT’s international portfolio, not whether it crosses a round number.
One Supplier, Several Large Claims on Its Output
NTT is not Bloom’s only large data center customer. Oracle agreed in April 2026 to procure up to 2.8 gigawatts of Bloom fuel cells, Brookfield formed a $5 billion partnership with Bloom in late 2025 to deploy the technology at AI data centers globally, and Equinix expanded its deployment in August 2025 to more than 100MW across 19 data centers. Adding NTT to Oracle produces up to 3.7 gigawatts across just those two agreements, although Oracle’s figure is a ceiling rather than a confirmed volume.
Those figures do not establish a shortage. They do make allocation a fair question, because a buyer that relies on fuel cells as primary power needs its delivery slots to hold even as other customers draw on the same supplier. The Equinix numbers also show how much the size of these deals has grown: its deployment averages a little over 5MW per data center, while NTT’s single agreement reaches 900MW across an unspecified number of projects.
Geography adds another layer. NTT opened 10 facilities across North America, EMEA (Europe, the Middle East and Africa) and APAC (Asia-Pacific) in the year to December 2025. If the deployment spans a similar footprint, Bloom’s largest international project will have to work through differing permitting regimes, installation workforces and fuel arrangements. That makes field execution as important as factory output.
The Benefits Claimed Still Need Numbers
Adams says the fuel cells “protect local air quality, use minimal water and run quietly, which matters to us just as much as the megawatts.” Generating power without combustion is a real technical distinction, and these are the factors that often shape community response to a new data center. Even so, the claims are qualitative. Emissions, water use and noise figures for specific sites would let communities, regulators and customers test them.
The same applies to Joshi’s description of “highly reliable, cleaner power.” Cleaner depends on the comparison and on the fuel, since a fuel cell still needs one. NTT’s separate July 2026 partnership with ENGIE, aimed at decarbonization, energy resilience and sustainable expansion, makes that question more pertinent: buyers will want to see how the onsite plan and the decarbonization goals fit together.
Background
NTT Global Data Centers operates facilities across North America, EMEA and APAC and opened 10 new sites in the year to December 2025. Its parent brand, NTT DATA, plans to invest more than $10 billion through 2027 in AI-ready infrastructure and announced a partnership with ENGIE in July 2026 covering decarbonization, energy resilience and sustainable expansion across its global data center operations.
Bloom Energy makes modular fuel cells that generate electricity without combustion, and it has become a growing supplier to the data center market. Its recent agreements include Equinix’s expansion to more than 100MW across 19 data centers in August 2025, a $5 billion partnership with Brookfield in late 2025 and Oracle’s April 2026 agreement to procure up to 2.8 gigawatts.
