FuelCell Energy Inc. (NASDAQ: FCEL) announced the launch of standardized 12.5-megawatt power blocks designed for data center applications and plans to expand manufacturing capacity at its Torrington, Connecticut facility.

The company stated its business development pipeline increased by 275% since February 2025, with most growth attributed to data center customers. FuelCell Energy plans to increase manufacturing capacity from approximately 100 MW to 350 MW at its Connecticut facility to meet anticipated demand.

The new 12.5 MW system packages ten 1.25 MW modules into a standardized block intended to reduce site-specific engineering and permitting work while speeding deployment for data centers facing grid constraints and power availability limitations.

"The challenge facing data centers today isn't just how much power they need — it's how quickly they can get it," said Jason Few, president and chief executive officer of FuelCell Energy.

The company now offers three core product blocks for data centers: a 1.25 MW system, a 2.5 MW system comprising two 1.25 MW modules, and the new 12.5 MW system consisting of five independently operating 2.5 MW fuel cell systems with shared infrastructure.

FuelCell Energy's fuel cell systems generate electricity electrochemically rather than through combustion, resulting in quiet operation and reduced air emissions. The technology includes heat-driven cooling that reduces supplemental cooling infrastructure requirements.

The company will demonstrate the new offering at DCD>Connect New York on March 24. Initial investments for the manufacturing expansion will focus on long-lead items including high-capacity equipment, according to the company's statement.

FuelCell Energy is pursuing a hub-and-spoke manufacturing model to reduce costs and localize final assembly, similar to approaches used in South Korea and Germany.
