What decides what a data center developer will pay for land?

What the land could become, how likely that is, and how long it will take. A data center developer is not paying for the crops or the grazing. It is paying for the chance that the land can be zoned, connected to a large supply of power and built on, minus the money and years it will have to spend to get there. Two parcels of the same size in the same county can be worth very different amounts for this use, almost entirely because of the power. That is why nobody can give a fair number before looking at the specific ground.

How do appraisers decide what land is worth?

They start from its highest and best use. The federal government’s appraisal standards for land it acquires, known as the Yellow Book, say a use only counts if it is physically possible, legally permissible, financially feasible, and produces the highest value. All four tests have to be met.

The second test is where data center land gets interesting. A farm field is rarely zoned for a data center. The Yellow Book says it is legally improper to assume that a permit, license or rezoning would be obtained, and that the question is instead whether there is a reasonable probability of it. The IRS uses the same idea in its guide to valuing property: if a higher use would need a change in zoning, the appraiser must address whether it is reasonably probable that the change would be permitted. The IRS also lists available utilities among the things an appraiser should compare when valuing land.

In plain terms, the market pays for a future use in proportion to how likely it is. Land with a realistic path to power and approvals carries some of that value. Land without one is worth what it is worth as a farm.

Why does the power matter more than the acreage?

Because the power is what is scarce. Penn State Extension noted that developer inquiries to Pennsylvania landowners, though spread across the state, had been limited to properties near high voltage power lines and substations. The American Farm Bureau Federation lists closeness to stable, high capacity power grids first among the factors in data center site selection, followed by fiber, natural disaster risk, climate and incentives.

Capacity on the grid is not even across a region. North Dakota’s Transmission Authority describes research to find more affordable load pocket areas, the places where the existing grid can take a large new load at lower cost, and calls the current search for them a data scouting challenge. A tract near one of those pockets and a tract twenty miles away are not the same opportunity, even if they look alike from the road. Our guide to what powered land is explains why being near a line is not the same as having its power.

What does the developer have to spend before the land earns anything?

A lot, and utilities now make the developer carry it. Every dollar of it is money spent before the land produces any return, and it shapes what a buyer can afford to pay.

• Study fees. Texas SB 6 requires a flat study fee of at least 100,000 dollars for the first transmission screening study of a large load, and requires the customer to show site control through ownership, a lease or another legal interest.
• Financial commitments. The same Texas law requires uniform financial commitments for the transmission needed to serve a large load. AEP Ohio’s data center tariff makes the customer pay minimum charges for the initial term even if it curtails or ends service, and requires collateral equal to half of the total minimum charges from customers without strong credit.
• Paying for the build out. AEP Ohio’s letter of agreement requires the customer to reimburse 100 percent of the buildout costs if it cancels, or delays by more than 12 months. Near Harwood, North Dakota, the Transmission Authority reports that a new 345 kilovolt line and substation for a data center will be fully funded by the developer, and Basin Electric’s large load program is designed so the large load covers the costs it creates.

How do time and risk change the price?

They lower it, because a buyer discounts for every year it waits and every thing that could still go wrong.

The grid takes time. ERCOT told Texas senators in April 2026 that it was tracking about 410 gigawatts of large loads seeking to connect, about 87 percent of them data centers, and that projects can be pulled into repeated restudies that extend timelines by years. AEP Ohio says that where regional transmission upgrades are needed, its estimate of when power will be available is high level and depends on many factors outside its control.

Approvals can fail. Ohio State’s agricultural law program reported that residents in at least 19 Ohio communities would vote on data center issues on November 3, 2026. Roger McEowen, writing on agricultural law for RFD-TV, notes that data centers frequently need rezoning, conditional use permits or development agreements, and that a landowner should ask what happens if zoning is denied.

Developers pursue more than one site. Texas now requires large loads to tell the utility whether they are pursuing a substantially similar request elsewhere in the state, which shows how common it is. Any one site can be dropped when another comes through first.

Why is an option payment smaller than the sale price?

Because the option buys time, not land. Ohio State’s guide for farmland owners explains that an option binds the landowner but does not bind the developer to go ahead. Payment can be a lump sum, a signing payment plus an annual amount, or an annual amount alone, and the guide notes that payments are typically at their lowest during the option period. Penn State says option terms typically run two to five years, that option payments vary and can be negotiated, and that many options signed for solar are never developed.

That is the trade. The developer pays a smaller amount now for the right to buy later at a set price, once it knows whether the power and approvals will come through. McEowen’s advice to landowners is to negotiate definite expiration dates, escalating non-refundable option payments, real limits on assignment, and the right to keep farming during the checking period. We cover what an option commits you to in how you sell land to a data center developer.

Are data centers pushing up farmland values?

In some places, and the surveys say it varies a great deal from one area to the next. Purdue’s 2025 survey of Indiana farmland reported respondents saying that development, solar farms and data centers were driving prices in their market areas, and that the effect can spread to neighboring counties when sellers buy replacement land through 1031 exchanges. Purdue’s outlook for 2026 named development pressure, including emerging data center activity, as a key factor supporting higher values.

Purdue’s August 2026 report found that land conversion was among the strongest positive forces on values, but also recorded at least one respondent reporting very little development demand in their area, and high variation within local areas depending on the pace of nearby development. The Farm Bureau’s economist observes that as more parcels are rezoned or considered for rezoning, farmland begins to carry speculative value tied to future development.

A higher price on one farm near a project tells you something about that farm. It tells you much less about the next one.

How can I understand what my own land might be worth?

• Get your own appraisal from an appraiser who has never worked for the buyer, and ask what use it assumes.
• Know what is tied to your land: easements, leases, farm program contracts, pipelines and who owns the minerals.
• Ask any buyer what their price assumes about power, zoning and timing, and what happens to the price if those change.
• Read the payment terms, not just the headline number. An option payment, an extension payment and the final price are three different things.

Where do we fit in this?

We buy or option land ourselves and develop it into sites data center companies want. Our price depends on the same things this article describes, which is why we do not quote a figure for land we have not looked at. We check the power first, at our own cost, and we say no to most land for that reason. The county, a rough acreage and anything you can see nearby is enough for us to start.
