FS-1 · Flagship Campus · Eastern US

Power. Scale. Sovereignty.

FS-1 is Fullscale's flagship AI compute campus — built with source-flexible on-site power generation, direct fiber, and a modular architecture engineered to expand from 300 MW to beyond 1 GW on the same footprint.

Site Architecture

A repeatable block model.

FS-1 launches at 300 MW and proves the modular block model. Each block is an independent unit of capacity — its own power, cooling, white space, and connectivity. Blocks add without disturbing the blocks already running.

Phase 2 expands FS-1 to 1 GW+ on the same footprint, simply by adding additional blocks against the existing power and fiber backbone. No rebuild. No stranded capital. No site transition. The campus grows as capacity is committed.

Phase 3 takes the model national. The infrastructure platform that builds FS-1 builds again — additional campuses, additional gigawatts, the same operating model.

Three Phases

From flagship to national platform.

Phase I · Launch
300 MW. Flagship.
Initial operating capacity. Behind-the-meter power generation, white-space environments, direct fiber. The flagship that proves the model. Status: in development.
Phase II · Expansion
1 GW+. Same site.
Additional modular blocks on the same campus. Same power infrastructure, expanded. Growth without rebuild, stranded capital, or disruption to existing operations.
Phase III · National
Multi-GW. Multiple sites.
FS-1 proves the playbook. The platform replicates it at every new campus site. The infrastructure layer for American AI compute.

Why FS-1

Every decision intentional.

01 · Power
Source-flexible. Speed-first.
Behind-the-meter primary energization with strategic utility alignment engineered in from day one. Sites are selected for fast energization paths, with the long-term grid integration sequenced and ready for Phase 2.
02 · Modular
Same block, repeated.
Every block is built the same way. Add capacity without disrupting operations. The architecture scales cleanly from 300 MW to 1 GW+ on the same footprint.
03 · White Space
Customer-controlled.
Bring your own hardware, your own stack, your own architecture. Fullscale provides the infrastructure — you control the compute.
04 · Refresh
Built for the curve.
AI hardware generations arrive every 12–18 months. Modular build means you swap blocks, not campuses. Infrastructure stays current without stranded investment.

Capacity is being structured now.

FS-1 capacity commitments are open. Early partners shape the platform. This window does not stay open indefinitely.
