FuelCell Energy Signs First Data Center Reservation for 75 MW Texas Power Project
FuelCell Energy has signed its first capacity reservation agreement with a major data center operator, reserving manufacturing capacity for six fuel-cell blocks planned to provide 75 MW of onsite power at a Texas data center.

FuelCell Energy disclosed September 2 that it has signed its first capacity reservation agreement with a major data center operator for a planned 75 MW project in Texas, reserving manufacturing capacity for six modular fuel-cell power blocks while the parties negotiate definitive project agreements. The FuelCell Energy Texas data center power development matters because it gives an unnamed operator priority access to onsite generation as Texas scrutinizes a rapidly expanding queue of large computing loads.
The planned system would consist of six 12.5 MW FuelCell Energy Blocks, providing 75 MW of modular generation. According to FuelCell Energy’s September 2 business update, the data center operator has made an upfront reservation payment, allowing the manufacturer to reserve production capacity and begin procuring long-lead components.
The agreement reserves capacity but is not a completed power project
The commercial structure is important. FuelCell Energy has signed a Capacity Reservation Agreement rather than a final contract covering construction and operation of the complete 75 MW project.
The reservation gives the data center operator priority access to manufacturing capacity while definitive agreements are negotiated. FuelCell Energy did not disclose the customer’s identity, the reservation payment, the precise Texas location or a commercial-operation date.
The company separately reported the agreement through a September 2 Form 8-K filed with the Securities and Exchange Commission.
Independent reporting from StreetInsider also confirmed the six-block, 75 MW reservation and the absence of disclosed financial terms.
Fuel cells provide a behind-the-meter power option
Fuel cells generate electricity electrochemically rather than through conventional combustion. For large data centers, modular stationary systems can be installed near the load and used as dedicated generation rather than waiting for the utility grid to provide the entire site’s required capacity.
The strategy is part of a broader move toward onsite and behind-the-meter infrastructure as AI developers confront constrained transmission systems and long utility interconnection timelines.
Microgrid Media has previously covered Microsoft’s 100 MW California data center microgrid, another example of computing infrastructure pairing utility access with large-scale onsite generation.
Fuel cells can also operate as one component within a more complex microgrid. A microgrid controller can coordinate fuel cells with batteries, utility power and other distributed resources when a site uses multiple energy technologies.
The Texas grid is facing unusually large data center requests
The timing is significant because Texas has become one of the country’s most active data center development markets while utilities and grid planners attempt to separate viable projects from speculative power requests.
Reuters reported September 1 that Texas has halted new data center grid connections while conducting an audit intended to verify projects and address so-called ghost demand.
Microgrid Media has separately reported that more than 17 GW of proposed large loads entered CenterPoint Energy’s Batch Zero process in the Houston region, illustrating the scale of electricity requests utilities are being asked to evaluate.
An onsite generation project does not remove every grid constraint, particularly if the data center also requires substantial utility service, but it can reduce the amount of capacity that must be delivered through the external transmission and distribution system.
FuelCell Energy is expanding manufacturing
The Texas reservation arrives as FuelCell Energy increases production and expands its Torrington, Connecticut manufacturing facility.
The company operated at an annualized production rate of 37.1 MW during its fiscal third quarter and is targeting 100 MW in October 2026. It plans to expand Torrington to 500 MW of annualized manufacturing capacity by June 2028.
That expansion would support a much larger data-center pipeline. FuelCell Energy said its fiscal 2026 sales pipeline reached approximately 10 GW during the quarter.
The company also has a separate agreement with Fit Energy covering an initial 30 MW commitment and options that could bring the total to as much as 380 MW of fuel-cell generation intended for data center applications.
The company’s backlog is growing while losses remain substantial
The data center strategy is developing against a financially mixed backdrop.
FuelCell Energy reported $33 million of fiscal third-quarter revenue, down from $46.7 million a year earlier. Its gross loss widened to $24.5 million from $5.1 million, while the company’s net loss narrowed to $45.3 million from $91.9 million.
Committed backlog stood at $1.3 billion as of July 31. FuelCell Energy also reported approximately $2.35 billion of awarded capacity backlog, driven primarily by the Fit Energy arrangement.
Those figures reinforce the distinction between commercial pipeline, reserved or awarded capacity and operating generation. Converting prospective data center demand into completed projects will depend on definitive contracts, manufacturing execution, site development and customer financing.
What happens next
The next milestone for the FuelCell Energy Texas data center power project is the negotiation of definitive agreements with the unnamed operator.
FuelCell Energy will meanwhile reserve production capacity and begin procurement of long-lead equipment under the existing reservation arrangement.
If the project advances, the six-block deployment would provide a useful test of whether modular fuel-cell generation can help large Texas data centers move toward operation without relying exclusively on new utility-delivered capacity.
