Most data center site checklists list twenty factors with equal weight. In 2026 one of them, deliverable power by a date, decides most deals. This checklist puts the checks in the order that kills bad sites fastest, so you spend money on parcels, surveys and options only for sites that can close.
Before you start
- Check power evidence first. Everything else is wasted effort if the MW is not real.
- Kill sites that are claimed, contaminated or under a moratorium before parcel work.
- Model large-load tariff terms as part of price.
- Grade each site A, B or C by power evidence.
The checklist, in order
- Set the MW (IT and facility), ramp and energize-by date.
- Find the document behind the site’s MW: map, named MW, load study, signed agreement or metered service.
- Confirm substation withdrawal headroom for your load under contingency.
- Check the serving utility’s large-load tariff: study fees, collateral, minimum bill, term.
- Kill sites that are already claimed, under option or operating for someone else.
- Check environmental liability: coal ash, contamination, deed restrictions, liability-buyer owners.
- Screen the county and any annexing city for moratoriums, ordinances and recent denials.
- Confirm the zoning path: by-right, special use or rezoning.
- Work out usable acres after wetlands, floodplain, slope, easements and setbacks; reserve the substation corner.
- Confirm water for cooling and fire, or a low-water cooling design.
- Confirm fiber routes and latency needs.
- Lay out the permit path: air permits for generators, stormwater, building and fire.
Why order matters
Each check costs more than the one before it. A utility call is cheap; a wetland delineation, a survey and an option fee are not. Running them in this order kills most sites before they cost anything.
Sites available through Invariant now
A selection from Invariant’s current US inventory that fits this search. Specs are as marketed by the owner and are checked against utility documents before any introduction.
| Region | Power | Land | Timing |
|---|---|---|---|
| Pennsylvania | 350 MW, signed utility service agreement | Former plant campus, lease | 50 MW end 2026, 300 MW end 2027 |
| Ohio | 300 MW approved | 300+ acres | 1H 2027 |
| Indiana | 200 MW, load study done | ~80 acres | Substation planned |
| Wisconsin | 150 MW built, 80 MW now | 130 ready acres | Now |
Exact locations, the utility documents behind each MW figure and pricing are shared on a call. We also hold sites that are not listed publicly; owners ask for discretion and a site that is shopped everywhere loses value.

Questions that come up.
What is the most important factor in data center site selection?
Deliverable power by a date. Check the utility document behind the MW and the substation headroom before anything else.
What should a data center site selection checklist include?
Power evidence, substation headroom, tariff terms, claims and liabilities, moratoriums and zoning, usable acres, water, fiber and permits, in that order.Data Center Watch
