FS-1 is Fullscale's flagship AI compute campus — built with behind-the-meter power generation, direct fiber, and a modular architecture engineered to expand from 300 MW to beyond 1 GW on the same footprint. No grid queue. No rebuild. No ceiling.
FS-1 is built on a repeatable modular block architecture. Each block adds capacity without disturbing existing infrastructure. Phase 1 proves the model. Phase 2 and 3 compound it.
Every infrastructure decision at FS-1 was made for AI-scale compute — not adapted from legacy data center assumptions. Power-first. Density-first. Refresh-ready. Grid-independent from day one.

FS-1 launches at 300 MW and proves the model. The campus expands to 1 GW+ on the same footprint. Then Fullscale replicates it — multiple campuses, multiple GW, one operating system.
Initial operating capacity at scale. Behind-the-meter power generation, white-space environments, and direct fiber. This is where Fullscale proves the model.
In DevelopmentSame site. Additional modular blocks. No rebuild. No stranded capital. The same power infrastructure, expanded. Growth that compounds without friction or disruption.
Phased ExpansionMultiple campuses. Multiple GW. One operating model. FS-1 proves the playbook — the platform replicates it at every new site. The infrastructure layer for American AI.
Already in MotionFS-1 capacity commitments are open. Early partners shape the platform. This window does not stay open indefinitely.
