Connecticut-based FuelCell Energy on June 22, 2026 signed a capital equipment purchase agreement with Fit Energy USA LP to build up to 380 megawatts of on-site, baseload fuel-cell power for data centers, assembled from 2.5-megawatt carbonate fuel-cell blocks and delivered across four phases. Fit Energy placed an immediate deposit on an initial 30 megawatts, with first deliveries starting later in 2026. FuelCell Energy shares climbed after the announcement.
How the Deal Is Structured
After the initial 30 megawatts, Fit Energy holds options for 100 megawatts in phase one, 125 megawatts in phase two, and a further 125 megawatts in phase three, reaching the 380-megawatt total. FuelCell Energy also granted Fit a warrant for up to 12 million shares at $26.44 each, vesting in tranches tied to deposits on as much as 350 megawatts of platforms. Fit Energy’s model pairs the fuel cells with behind-the-meter, microgrid, and grid-connected configurations.
What Is Genuinely New
Carbonate fuel cells run continuously on natural gas or biogas and produce steady baseload output, unlike the backup gensets or grid ties that most data centers depend on today. That makes the platform a direct answer to the interconnection queues stalling large loads: on-site generation sidesteps the multi-year wait for utility capacity. Bloom Energy has pushed the same on-site pitch with solid-oxide fuel cells; FuelCell Energy’s carbonate design competes on continuous baseload and heat recovery.
Critical Perspective
FuelCell Energy’s agreement with Fit Energy is headlined at 380 MW, but only the initial 30 MW carries an actual deposit while the remaining 350 MW sits in phased options tied to a warrant for 12 million shares at $26.44. An options-and-warrant structure rewards signing more than it guarantees megawatts built, so the firm order is a fraction of the number that lifted the stock. Bloom Energy struck a comparable framework for up to 1 GW with American Electric Power in 2024 that carried only a 100 MW initial commitment, showing how data-center fuel-cell deals lead with ceilings rather than firm volume. How much of the 350 MW of options actually converts to deployed capacity once each phase must clear its own financing and gas-supply hurdles?
Why It Matters
Data-center developers are chasing firm power that arrives faster than new transmission or gas plants. A 380-megawatt on-site order signals that fuel cells are moving from pilot volumes toward campus-scale supply. For the grid, every megawatt served behind the meter is load that does not queue for interconnection, though the natural-gas feedstock keeps the carbon question open.
