FuelCell Energy, Inc. is introducing standardized packaged 12.5-megawatt (MW) power blocks to enable faster deployment of on-site, utility-scale continuous power for data centers in grid-constrained markets. The company is also expanding manufacturing capacity at its Torrington, Conn. facility to meet expected demand, which has increased by 275% since February 2025, with the majority coming from data center customers.

Why it matters

Grid congestion, interconnection backlogs, and permitting delays have increasingly slowed data center construction, leading developers to seek ways to secure reliable power without waiting on utility infrastructure. FuelCell Energy's standardized 12.5 MW power blocks aim to address this bottleneck and enable large data center projects to move forward faster in power-constrained markets.

The details

FuelCell Energy's packaged, standardized, and scalable 12.5 MW on-site power system is comprised of 10 proven 1.25 MW modules. This approach allows data center developers to add capacity in phases while relying on a platform with a long operating track record, reducing the need for repeated engineering and integration as projects scale. Unlike combustion-based generators, FuelCell Energy's systems produce power electrochemically, resulting in quiet operation and low air emissions, which are key advantages for data centers facing permitting and siting constraints.

  • FuelCell Energy will highlight the new 12.5 MW offering at DCD>Connect New York on March 24, 2026.
  • The company plans to expand manufacturing capacity by more than three times over time at its Torrington, Conn. facility from approximately 100 to 350 MW to meet expected demand.

What they’re saying

“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”

— Jason Few, President and Chief Executive Officer

“Customers want fast, phased deployment. Our 12.5 MW Block provides an ideal balance, delivering both economies of scale and modular reliability. By implementing these solutions at our customers' sites, we give them a reliable platform that can grow over time — without the challenges of connecting multiple smaller systems.”

— Eric Strayer, Senior Vice President and Head of Global Sales

What’s next

FuelCell Energy will now offer three core product blocks for data centers, with the option to add others over time: the FuelCell Energy Block 1.25 MW System, the FuelCell Energy Block 2.5 MW System, and the FuelCell Energy Block 12.5 MW System.

The takeaway

FuelCell Energy's standardized 12.5 MW power blocks aim to help data centers secure reliable on-site power faster amid grid constraints, enabling large projects to move forward more quickly in power-constrained markets. This solution reduces uncertainty around timelines, infrastructure readiness, and grid availability, aligning power delivery with the pace of AI-driven development.
