Energy Platform
100 GW solar compute zone — capacity model, contracts, and developer access.
The Xcity Energy Platform turns 400,000 hectares of San Juan solar irradiance into compute capacity. As a developer you don’t interact with it directly — your inference runs on it by default. As an enterprise buyer you can contract for dedicated capacity, carbon attribution, or off-take agreements.
Capacity
| Phase | Online | Target |
|---|---|---|
| Phase 1 (pilot) | 100 MW | 2026 Q3 |
| Phase 2 | 5 GW | 2027 |
| Phase 3 | 30 GW | 2029 |
| Final | 100 GW | 2031 |
San Juan averages 300 sunny days/year. Capacity factor on tracking arrays projects 28–30% — see the Solar Compute paper.
Inference attribution
Every inference request gets a carbon line in its response header (Enterprise only):
X-Xcity-Carbon-gCO2e: 0.34
X-Xcity-Energy-Source: solar
We don’t claim 100% solar coverage outside daylight hours — battery storage covers ~80%, grid backup the rest. Enterprise customers can choose solar-only mode (requests queue during low-availability windows, never grid-backed).
Off-take
For enterprises with their own compute, we sell renewable energy off-take contracts in 10 MW blocks. Includes:
- Settlement at agreed PPA price
- REC delivery
- Optional fiber + direct-current handoff from the solar zone
