FuelCell Energy Introduces Standardized 12.5 MW Power Blocks for Data Centers

FuelCell Energy announced a standardized 12.5 MW packaged power block solution targeting data center operators facing power availability constraints. The offering addresses grid congestion, interconnection backlogs, and permitting delays that slow data center construction by providing on-site, utility-scale continuous power generation.

The 12.5 MW block comprises five independently operating 2.5 MW fuel cell systems supported by shared balance-of-plant infrastructure. This modular approach reduces site-specific engineering, permitting work, and integration risk while accelerating deployment across multi-phase projects.

The company plans to expand manufacturing capacity at its Torrington, Connecticut facility from approximately 100 MW to 350 MW to meet anticipated demand. FuelCell Energy's business development pipeline increased 275% since February 2025, with data center customers representing the majority of new opportunities.

FuelCell Energy's electrochemical power generation produces lower air emissions and quieter operation than combustion-based generators, offering advantages for permitting. The systems' heat-driven cooling reduces supplemental cooling infrastructure needs, allowing more electrical capacity for IT operations.

The company will now offer three core product blocks: 1.25 MW, 2.5 MW, and 12.5 MW systems. CEO Jason Few emphasized that data centers require infrastructure-grade solutions enabling both immediate deployment and long-term scalability.
