Built to deliver what matters most: electrons to the grid.
AI compute, advanced manufacturing, and electrification are outpacing the grid we have today. Long-duration storage is the keystone of what comes next — the asset class that makes the grid reliable, flexible, and economically viable for the gigawatts now coming online. Demand is moving faster than the domestic supply chain can presently meet. FPUSA was built to close that gap — capturing the opportunity at gigawatt scale, with capital and underwriting committed before a project breaks ground and committed access to Eos’ American-built technology stack.
The Eos technology stack — all-American, long-duration performance.
/ Eos Z3™
Z3 is the latest generation of Eos’ zinc-powered battery module. A nonflammable aqueous chemistry that eliminates thermal runaway risk, enables flexible discharge and daily multi-cycling without degradation or augmentation, and qualifies as domestic, FEOC-compliant content out of the box.
/ Eos Indensity™
Indensity is the Eos system architecture engineered for next-level energy density per acre. With a configurable, modular plug-and-play design, rotable servicing components, and continuous nameplate performance across a 20+ year life — it turns every deployment into a multi-decade industrial services relationship.
/ Eos DawnOS™
DawnOS is Eos’ proprietary controls and analytics layer that runs every FPUSA-deployed asset. Real-time monitoring, dispatch optimization, and fleet-wide performance learning convert each project into a long-tail data and software relationship — compounding the operational advantage with every new deployment.
