Site Selection, Power Procurement & Permitting

13 chapters

3.1
Site Selection Strategy & the Reordered Criteria Hierarchy
For a program seeking 100 MW to multiple gigawatts in a 24–48-month window, site selection screens power first — where that capacity can be energized by the need date — because in 2026 it eliminates more candidates than land, latency or price; workload/network, cooling, land and legal delivery are the other mandatory gates, so price speed only among sites that clear all of them, and confirm no other gate binds before calling power the constraint.
3.2
Grid Access, Large-Load Service & Speed-to-Power
Grid access is often the schedule gate, but the governing path is jurisdiction-specific: start with the host utility's large-load service process, then add a separate generator/export interconnection path only where the project actually exports or interconnects generation.
3.3
Power Availability & Power-Cost Structure
Power’s share of lifetime opex depends on whether the denominator includes the GPUs, facility and financing. Underwrite the delivered bill through ramp and curtailment: price, shape, fixed charges and exit terms signed at siting survive the chip purchase.
3.4
Energy Supply Strategy: Grid PPA, BYOP & Co-Location
The supply structure — grid-only, grid-plus-bridge, behind-the-meter island, or co-located hybrid — assigns the obligations that must deliver the energization date and cost, and its basis, shape, and regulatory risks outlive the GPU generation it powers.
3.5
On-Site & Bring-Your-Own-Power Generation (Energy-Supply Strategy)
When the grid cannot energize a campus on schedule, a qualified on-site generation path competes with waiting for grid service, and the bridge-vs-permanent call governs prime mover, fuel firmness, emissions exposure, and stranding risk.
3.6
Fiber, Latency & Network Connectivity (Secondary Screen)
Fiber diligence turns on physics — roughly 5 microseconds of one-way delay per route-kilometer — which bounds how far apart campuses can train as one machine and how far an inference metro can sit from its users.
3.7
Water Availability, Sourcing & Climate-Driven Cooling Strategy (Siting Gate)
Water availability and lawful discharge can independently reject a site: it sets the cooling architecture and the permit timeline, and your drought-year curtailment rank, not average-year supply, decides whether the asset keeps running.
3.8
Land, Geotechnical, Seismic & Flood Diligence (Secondary Screen)
Soil, seismicity, flood line, and title rarely pick the winning site, yet a missed liquefaction zone, an under-rated slab, or a 500-year-floodplain parcel can force a new layout, foundation or permit path after land has already been bought.
3.9
Permitting, Regulatory, Environmental & the Critical Path
Grid interconnection and the air permit for backup generation routinely outrun construction, so start each governing application when its site-control and evidence prerequisites permit — otherwise a finished campus sits dark.
3.10
Tax Incentives, Fiscal Structuring & Economic Development
Incentives can distinguish sites that already clear the mandatory gates; the 10-year abatement banked against a 20–30 year asset is the most reversible line in the pro-forma, so model qualification, sunset and recapture before banking the cash.
3.11
Community Relations, Opposition & Social License
Community consent now gates approval alongside power and water: lose the rezoning and you strand an interconnection slot and land you have already begun to underwrite.
3.12
Geopolitics, Sovereignty, Export Controls & Data Residency
Geopolitics now gates siting in 2026: whether your jurisdiction may receive top US accelerators, whose law can reach the bytes, and whether that answer survives a change of administration.
3.13
Market Clusters & the Site-Scoring Playbook
The market you pick pre-loads power, permitting, cooling physics, and sovereignty before you score a parcel; the scoring playbook keeps a tempting cluster from passing a gate it already failed.
