Model training and inference happen in buildings that must be sited somewhere, and in the United States that somewhere is chosen by county commissioners. The economics and the objections are both local.
Siting follows power, not talent
A large facility needs an interconnection to the grid at a scale most towns never contemplated. Available transmission capacity is the first filter, ahead of every other consideration.
That pushes construction toward places with existing generation, retired industrial capacity or transmission corridors already built. Rural counties in the Southeast, the Plains and the Mountain West qualify more often than coastal metros.
The workforce argument that drove earlier tech siting matters less here, because a finished facility runs with a modest permanent staff relative to its footprint.
Tax abatements are the negotiating instrument
Counties compete for these projects by discounting property tax over a term of years. The abatement is the main lever a small jurisdiction has to offer.
The tradeoff is immediate and legible to residents. Construction spending and utility payments arrive early, while the property tax base that would fund schools arrives only after the abatement expires.
School boards and county commissions frequently end up on opposite sides of the same deal, which is why the arguments get sharp in places with no history of technology politics.
Water use is the objection that scales
Cooling systems either use water or use more electricity to avoid it, and the choice is made per site based on climate and cost.
In parts of the West and Southwest where allocations are already contested, a new industrial draw becomes a permitting question with an organized constituency waiting for it.
Operators have responded with closed-loop and air-cooled designs, but those shift the burden back onto the grid, which returns the argument to the utility commission.
Ratepayers notice the bill before they notice the building
Large new loads require transmission upgrades, and the cost recovery for those upgrades runs through rate cases at the state public utility commission.
Residential customers who never see the facility can see the line item, and that connection turns an industrial siting question into a consumer one.
Several states have begun creating separate rate classes for very large loads, which is an attempt to keep the cost with the customer that caused it.
The decisions are made in rooms nobody watches
Planning commissions, zoning boards and rate hearings run on published agendas with sparse attendance. They are where the actual approvals happen.
National coverage arrives after a project is announced, by which point the rezoning and the abatement have usually been voted on already.
The physical geography of American compute is being set in these meetings, one parcel at a time, largely outside the debate about the models themselves.
