Data-center site selection: the criteria, in the order they end sites

Why order matters

A site can score well on nine factors and fail on one. If that one is a local pause or a power dead end, the other nine were wasted effort. We check the deal-ending questions first and spend the detailed work only on sites that survive them.

1. Can it be approved here?

Which government regulates the parcel, whether the use is allowed, by what process, and whether the board has paused it. A county and a town inside it can give different answers. See how to read a moratorium and a zoning label is only the beginning.

2. Is there a path to power?

The relationship of the tract to high-voltage transmission and substations, the serving utility, and the obstacles to a connection. Then the questions only the utility can answer: capacity, upgrades, cost, schedule, and a second feed. See a substation next door is not power.

3. Who are the neighbors?

Homes, schools, and places of worship nearby, and how this community has treated earlier proposals. See the neighbors decide more sites than the zoning map.

4. Is there enough usable, connected land?

Acreage after floodplain, wetlands, stream buffers, slopes, and easements, and whether what remains is in one workable piece. Then whether the site can expand. See gross acres are not usable acres.

5. Water, wastewater, and fire protection

Who could serve the site, what they report about supply and treatment, and what the provider must confirm. The cooling design changes how much this matters. See water and sewer.

6. Fiber

Providers on record, nearby interconnection points, and whether separate routes are truly separate. See fiber nearby is not fiber to the site.

7. Ground conditions

Soils, rock, groundwater, and slope, at the level public surveys allow. These decide cost more often than feasibility.

8. Environmental history and conservation interests

What has been recorded on and near the land, and any conservation easement that limits use. See environmental records.

9. Roads and heavy-haul access

The roads in, bridges and weight postings on the route, and whether a driveway permit is likely. See access and roads.

10. Taxes and incentives

State and local programs can change operating cost for the life of the campus. They rarely rescue a site that fails on the first three.

Two questions a checklist leaves out

Is the land actually available, and who can sell it? Suitability and availability are separate facts. A perfect tract with five heirs and no agreement is not a site yet.

Who is the buyer? The same land reads differently to an operator that will hold it and a developer that will prepare and sell it. See who buys data-center land.

Questions

What is the most important factor in data-center site selection?

Power, in the sense of a utility’s ability to deliver the load on the project’s schedule. In practice a local government’s position can end a site even sooner.

How long does site selection take?

Desktop screening of a candidate takes days. Utility studies, approvals, and engineering take months to years. Screening exists to make sure those months are spent on the right land.
