FuelCell Energy Launches 12.5 MW Power Blocks for Data Centers
Company plans to expand Torrington, Conn., facility from 100 MW to 350 MW as data center demand drives pipeline growth.
FuelCell Energy, fuel cell power company based in Danbury, Conn., launched standardized 12.5 MW power blocks for data centers on Monday, targeting grid-constrained markets where utility delays have slowed construction timelines.
The new product packages 10 of the company's proven 1.25 MW modules into a single integrated block, supported by shared balance-of-plant infrastructure. The design reduces site-specific engineering and permitting work that typically adds cost and time as data center projects scale.
"The challenge facing data centers today isn't just how much power they need — it's how quickly they can get it, and if the power they buy today will provide the power they need tomorrow," said Jason Few, President and CEO of FuelCell Energy.
The company now offers three standard configurations: the 1.25 MW system, a 2.5 MW system comprising 2 modules, and the new 12.5 MW block made up of five independently operating 2.5 MW systems.
FuelCell Energy's business development pipeline has grown 275% since February 2025, with data center customers accounting for the bulk of that increase. Q1 fiscal 2026 revenue came in at $30.5 million, up roughly 61% year-over-year, with the company reporting over 1.5 GW of new proposals in its pipeline.
The company plans to expand manufacturing capacity at its Torrington, Conn., facility from approximately 100 MW to 350 MW over time. Capital has been allocated this year for long-lead equipment. FuelCell Energy is also pursuing a hub-and-spoke manufacturing model for final assembly, drawing on experience from operations in South Korea and Germany.
The systems produce power electrochemically rather than through combustion, resulting in low air emissions and quiet operation. Heat generated by the process can be used for absorption chilling, reducing the electrical load required for cooling and freeing more power for compute operations.
In January, FuelCell Energy and investment firm Sustainable Development Capital LLP announced a strategic collaboration to explore deploying up to 450 MW of fuel-cell systems for data centers globally. Monday's product launch gives that pipeline a defined, standardized vehicle for deployment.
The broader fuel cell sector has moved in the same direction. Equinix contracted over 100 MW from Bloom Energy across 19 data centers, and American Electric Power placed an initial 100 MW order for behind-the-meter fuel cell capacity for large data center customers. FuelCell Energy's molten carbonate technology targets utility-scale, off-grid baseload applications.
The company will demonstrate the 12.5 MW block at DCD>Connect New York on March 24. FuelCell Energy has approximately 1 GW of global fuel cell deployments and more than 23 years of manufacturing experience.
