FuelCell Energy Launches 12.5 MW Power Blocks for Data Centers

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.
