Site Selection, Power Procurement & Permitting

For a 100 MW to multi-gigawatt program on a 24–48-month clock, screen power first: where can firm capacity energize by your need date? In 2026 that eliminates more sites than land, latency or price, so price speed only among sites that clear every mandatory gate.

Grid access is often the schedule gate, and the governing path is local. Start with the host utility's large-load service process; add a generator-interconnection path only if you export power or interconnect generation. Mix them up and you plan against the wrong clock.

Power is the largest operating cost but only about 7% of annualized TCO in Epoch AI’s 1 GW model. Underwrite the delivered bill through ramp and curtailment: the price, shape, fixed charges and exit terms signed at siting outlast the chip purchase.

Your supply structure (grid-only, grid plus bridge, behind-the-meter island or co-located hybrid) decides who must deliver your energization date and at what cost. Its basis, shape and regulatory risks outlive the GPU generation it powers.

When the grid cannot energize a campus on schedule, on-site generation competes with waiting for grid service. Whether the plant is a bridge or permanent decides the prime mover, fuel firmness, emissions exposure and stranding risk.

Fiber diligence turns on physics: light needs about 5 microseconds 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. Fiber that misses the workload's budget can sink a site.

Water availability and lawful discharge can each reject a site. Water sets the cooling architecture and the permit timeline, and your curtailment rank in a drought year, not average-year supply, decides whether the asset keeps running.

Soil, seismicity, flood line and title rarely pick the winning site. But a missed liquefaction zone, an under-rated slab or a 500-year-floodplain parcel can force a new layout, foundation or permit path after you have already bought the land.

The grid connection and the air permit for backup or bridge generation usually take longer than construction. File each one as soon as you hold the site control and evidence it needs, or the finished campus stands dark.

Incentives break ties between sites that already clear the mandatory gates. Legislatures can repeal statutory sales-tax exemptions, and a 10-year abatement lasts a third to half of a 20–30 year asset life. Model qualification, expiry and clawback before you bank the cash.

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.

Geopolitics now gates siting: whether your jurisdiction may receive top US accelerators, whose law can reach your bytes, and whether that survives a change of administration. Miss it and the hall waits on chips that cannot ship.

The market you pick pre-loads power, permitting, cooling and sovereignty constraints before you score a single parcel. Run the mandatory gates first, so a tempting cluster cannot pass a gate it already failed.
