Key takeaways
- Feasibility answers one question: can this site deliver this load, on this land, on a timeline that works?
- Power availability and timing decide more outcomes than any other workstream.
- Buildable acreage, not gross acreage, sets what the site can actually hold.
- A good study ends with a clear verdict, the conditions behind it and the open items still to resolve.
- Feasibility is not diligence: it narrows the field before money is spent on surveys, borings and legal review.
01What question does a feasibility study answer?
A feasibility study asks whether a site can host a defined project. That definition matters. A 20 MW colocation building and a 300 MW hyperscale campus put very different demands on the same parcel, so the study starts by fixing the target: load in megawatts, phasing, building count, cooling approach and the date the first megawatts are needed.
With the target set, the study works through every factor that could stop or reshape the project. Some are hard knockouts, like a site that sits mostly in a regulated floodway. Others are conditions, like a site that works only if the utility builds a new substation. The output is a verdict and a list of what has to be true for that verdict to hold.
The study is not a design and not a legal opinion. It is a structured, evidence-based judgment about whether the site deserves the time and money that diligence and entitlement will cost.
02The core workstreams
Most feasibility studies cover the same workstreams. The depth in each depends on how far along the site is and what the client already knows.
| Workstream | Key questions | Typical evidence |
|---|---|---|
| Power | How much capacity, from which substation or line, at what voltage, and when? | Transmission maps, utility conversations, load or interconnection study results |
| Land | How many acres are buildable after constraints? Does the shape fit a campus? | Parcel data, constraint mapping, concept layout |
| Environmental | Floodplain, wetlands, protected species, contamination, slope and soils | FEMA FIRMs, NWI and soil data, desktop Phase I screening |
| Water and wastewater | Can the site meet the cooling design’s water needs and discharge? | Utility capacity, groundwater availability, permitting path |
| Fiber | How far to long-haul and metro routes? How many carriers? Diverse paths? | Carrier route data, carrier inquiries |
| Entitlement | Is a data center allowed by right? If not, what approval is needed? | Zoning code, comprehensive plan, local precedent |
| Airspace and hazards | FAA height limits, seismic, wind, wildfire and other hazards | 14 CFR Part 77 review, hazard maps |
| Schedule | What controls the date the site can be energized and occupied? | Combined view of power, permitting and construction timing |
03Power: the workstream that usually decides the answer
For most large sites, power is the deciding factor. The study needs to establish where the nearest usable transmission or substation capacity is, what voltage it runs at, how much headroom it has and what upgrades would be needed. Start with a realistic load figure; our guide to how much power a data center needs covers how to size it.
Distance to a line on a map is only the first clue. A site next to a 345 kV line may still face years of network upgrades, while a site farther out may sit near a substation with room to spare. That is why the study looks at substation proximity and capacity together, not distance alone.
At the feasibility stage, power findings are usually provisional. The utility’s formal answer comes through the large-load interconnection process, which can take considerable time. A good study states what is known, what the utility has indicated informally and what still depends on formal studies.
04Land, environmental and physical constraints
Gross acreage overstates what a site can hold. The study maps floodplain, wetlands, streams and their buffers, steep slopes, easements, setbacks and rights-of-way, then subtracts them. What is left is the buildable acreage, and its shape matters as much as its size. Large data halls, substations and generator yards need wide, regular footprints.
Environmental review at this stage is mostly desktop work: FEMA Flood Insurance Rate Maps, the National Wetlands Inventory, soil surveys, topography and records of known contamination. These sources are imperfect, so the study flags where field work such as a wetland delineation, geotechnical borings or a Phase I ESA is needed before a decision is final.
- Flood: how much of the site falls in Zone A/AE or shaded Zone X, and whether building pads can sit well above them.
- Wetlands and streams: likely jurisdictional features that would trigger Clean Water Act Section 404 permitting.
- Slope and soils: grading volume, rock, karst or poor bearing soils that raise cost.
- Species and cultural resources: known habitat or sites that could add review time.
05Zoning, permitting and community
A site that works physically can still fail on approvals. The study checks whether data centers are a permitted use under current zoning for data centers, or whether the project would need a special use permit, conditional use or rezoning. It also reviews the comprehensive plan, height limits, noise rules, setbacks and any local history with similar projects.
Community context is part of feasibility, not an afterthought. Neighbor proximity, local attitudes toward large industrial uses and recent public debate about data centers all affect how long and uncertain the approval path will be. The study should say plainly whether the path is routine, contested or unclear.
06Screening vs. feasibility vs. diligence
These terms get used loosely. They describe different levels of depth and cost, and each one feeds the next.
| Stage | Purpose | Depth | Typical output |
|---|---|---|---|
| Desktop screen | Eliminate sites that clearly fail | Mapped data, simple filters | Pass, fail or watch list |
| Feasibility study | Decide whether a site deserves pursuit | Desktop analysis plus targeted outreach to utilities, carriers and officials | Verdict, conditions, open items, concept layout |
| Due diligence | Confirm facts before closing or committing capital | Survey, title, Phase I ESA, geotech, wetland delineation, legal review | Reports and findings that support a transaction |
When feasibility is done well, diligence mostly confirms what is already expected. Our site due diligence checklist covers that next step.
07What a good feasibility report delivers
The report should be easy to act on. A reader should be able to see the verdict on the first page and trace every conclusion to its evidence.
- 01A clear verdict for the defined project: feasible, feasible with conditions, or not feasible.
- 02A constraint map and buildable acreage figure, with a concept layout where useful.
- 03A power summary: source, voltage, indicated capacity, upgrade needs and the realistic energization window.
- 04Water, fiber and gas findings with the level of confidence in each.
- 05The entitlement path and the main community considerations.
- 06A ranked list of risks and open items, each with the step that would resolve it.
The ranked risk list is the part clients use most. It tells them what to spend diligence money on first. Many of those risks are the same ones covered in why data center sites fail.
Common questions
How long does a data center feasibility study take?
It depends on scope and on how quickly utilities, carriers and local officials respond. A desktop-focused study on a single site can move in a matter of weeks. A study that waits on utility feedback or covers several sites can take longer. The formal utility interconnection study, if one is needed, is a separate process with its own timeline and usually runs well beyond the feasibility study itself.
What is the difference between a feasibility study and due diligence?
A feasibility study decides whether a site is worth pursuing for a defined project, mostly using mapped data and targeted conversations. Due diligence comes later and confirms facts before a closing or major commitment, using field work and legal review: an ALTA/NSPS survey, title commitment, Phase I ESA, geotechnical borings and wetland delineation. Feasibility narrows the field so diligence money goes to sites that are likely to work.
Who usually commissions a data center feasibility study?
Developers, operators and site selection teams commission them to compare candidate sites. Investors use them to test a land deal before committing capital. Large landowners and brokers sometimes commission one to understand what a property can realistically support before taking it to market. In each case the study is most useful when the target project, including load and timing, is defined up front.
Can a feasibility study confirm that power is available?
It can establish what is likely, based on transmission data, substation information and informal utility feedback, and it can flag what upgrades might be needed. Firm confirmation of capacity and timing comes only from the utility, usually through its formal large-load or interconnection study process. A good feasibility report states clearly which power findings are confirmed and which are indications.
