Powered Land
Powered Land for Data Centers: What It Is Worth, Substations, Interconnection and Behind-the-Meter Power
Data center buyers have paid $3.5 million to $4 million an acre for Northern Virginia land with power, many times the same land without it. Most "powered" listings overstate their power. We assess what a site can actually serve and what it is worth.
Assess My SitePowered land is land with an electrical supply a data center can actually use: a utility commitment, or on-site generation, for a defined number of megawatts by a defined date, close enough to transmission that the connection is buildable. It is the scarcest input in data center development, and it is priced accordingly. In the first quarter of 2026, data center land accounted for 30 percent of all development site spending in the US, up from 19 percent a year earlier, and entitled, power-ready parcels in the tightest submarkets now trade at many times the value of the same land without power. The word "powered" is doing a lot of work in most listings, though. A site next to a transmission line, a site with a load letter, a site with a completed utility study and a site with a signed facilities agreement are four very different assets. What a data center buyer pays for is the last one, and the gap between them is measured in years and in millions of dollars. Whether you have data center land for sale, are weighing a data center land acquisition, or hold a utility will serve letter and want to know what it is worth, the answer starts with where the site sits on the power ladder below.
Prices checked September 2026. Sources: NAHB, July 2026, for the county median and the Amazon and Starwood transactions; CBRE, February 2026, for pending transactions above $8 million per acre. Northern Virginia is the extreme; secondary markets price far lower, but the pattern is the same. Free to cite with a link to this page.
Send the location, acreage, zoning, and whatever you have on power: utility correspondence, study results, distance to transmission. You'll hear back within 24 hours from the principal who would assess it, with a first read on what the site can realistically serve and who would build on it.
What Makes Land "Powered": The Power Ladder
Every site sits somewhere on this ladder. Value, and the pool of buyers, rise sharply at each rung. The most common mistake in the market is pricing a site at a rung it has not reached.
| Rung | What exists | What it is worth to a data center buyer |
|---|---|---|
| 1. Near transmission | A line or substation nearby; nothing requested from the utility | An option, not a site. Proximity is necessary but proves nothing about capacity |
| 2. Load request filed | An application to the utility for a stated number of megawatts; a queue position | A place in line. Queues are long and often oversubscribed; a position is not power |
| 3. Will-serve or load letter | A utility letter indicating it can serve the load, usually conditional and often without a date | Meaningful but soft; read the conditions. Many letters promise study, not delivery |
| 4. Study complete | System impact and facilities studies done, with the upgrades, cost and timeline identified | Now the site can be underwritten: the capacity, the cost to connect and the energization date are known |
| 5. Agreement signed | An electric service or facilities agreement, with deposits or collateral posted and a date | Powered land in the sense buyers pay for. Most of the premium attaches here |
| 6. Energized | The substation built and power available at the fence | The top of the market; a building can start and tenants can lease against a real date |
Will Serve Letters: What They Promise and What They Do Not
A will serve letter is a letter from a utility stating that it is able and willing to provide service to a property, subject to conditions. Utilities issue them for water, sewer and gas as well as electricity, and for ordinary development they are routine. For a data center, the electric will serve letter is where many sites stop, and where many listings overstate their position. Read three things in it: the capacity (a stated number of megawatts, or only "service"), the date (a firm energization date, or none), and the conditions (usually completed studies, upgrades paid for by the customer, a signed service agreement and collateral). A letter that promises to study the load, with no megawatts and no date, is rung three at best. A letter tied to a completed facilities study with a date is worth far more. Buyers and lenders will read it the same way, so it is better to read it that way first.
Data Center Power Requirements
How much power a data center needs depends on how many racks it holds and how dense they are, plus the power used to cool and support them. The utility request, and the land, are sized from that.
| Workload | Power per rack | What it means for a site |
|---|---|---|
| Enterprise and cloud | About 5 to 15 kW | Air-cooled halls; a 10 MW building holds roughly a thousand racks |
| High density | About 30 to 60 kW | Liquid-assisted cooling; more power in less floor area |
| Rack-scale AI | About 120 to 140 kW for a GB300 NVL72, more for the next generation | Direct-to-chip liquid cooling, heavy floor loads, and power per square foot several times an enterprise building |
The utility sees more than the IT load. Cooling, power conversion and lighting add overhead, measured as PUE (power usage effectiveness): at a PUE of 1.3, a facility with 50 MW of IT load draws about 65 MW from the grid, and it is the grid figure that the utility request, the substation and the tariff are sized to. Campuses are now commonly planned at 100 MW and up, and a single hyperscale campus can reach several hundred megawatts. That is why the power a site can secure, rather than its acreage, usually sets how much data center it can hold. See data center cost for what each megawatt costs to build.
Large-Load Interconnection: What Utilities Require Now
Utilities used to connect large customers on standard terms. Since 2025, most of those serving data center demand have adopted large-load tariffs that shift the cost and risk of new capacity onto the customer: long minimum terms, minimum payments whether or not the power is used, collateral, and exit fees. They change the economics of a site, and they are why a load letter alone no longer means much.
| Utility or state | Threshold | Key terms |
|---|---|---|
| Dominion Energy, VirginiaGS-5 rate class | 25 MW and up, from January 1, 2027 | 14-year minimum contract; pay at least 85 percent of contracted transmission and distribution capacity and 60 percent of generation demand regardless of use; collateral of about $1.5 million per MW; four-year ramp |
| AEP OhioData Center Tariff | 25 MW and up | Pay at least 85 percent of contracted demand; 12-year minimum; exit fee of 36 months of minimum charges. After it was approved, AEP's large-load forecast fell by half |
| Texas, ERCOTSenate Bill 6 | 75 MW and up | Interconnection standards with financial commitments before study, batch studies, curtailment and remote-disconnect requirements; final rules expected by the end of 2026 |
| Georgia Power | Over 100 MW | Large loads pay for upstream grid infrastructure; developers must show end-user commitments and post collateral. See Atlanta |
| Elsewhere | Commonly 20 to 75 MW | Similar tariffs filed or approved across dozens of utilities; 44 of 77 large-load filings reviewed by CoBank include added collateral requirements |
Sources: CoBank DELTa database, April 2026; Berkeley Lab, August 2026; Columbia Law School, June 2026; Greenberg Traurig on Texas SB 6. Tariffs are changing quickly; confirm current terms with the utility.
The Data Center Substation
Above roughly 10 to 20 MW, a data center needs its own substation, fed from the utility's transmission or sub-transmission system and stepping down to the medium voltage the campus distributes. Large campuses connect at 138 kV or 230 kV, typically with two independent feeds. The substation, not the building, is almost always the longest item in the schedule.
What it costs
Core substation equipment typically runs $3 million to $7 million; a 69 kV substation of the kind common in suburban and rural areas, $6 million to $15 million. The full utility interconnection, including transmission lines, easements and utility charges, can run $20 million to more than $100 million depending on distance and voltage. Transformer prices have risen 40 to 55 percent since 2022.
How long it takes
Utility-grade transformers run 60 to 120 weeks from order; units of 100 MVA and up, 90 to 130 weeks or more. Switchgear runs 40 to 65 weeks. Developers who deliver on time order long-lead equipment during site control, before final design.
Who builds and pays
Either the utility builds it and charges the customer, or the developer builds and owns it, common above about 20 MW. Either way, the cost and the dates belong in the land underwriting, and a planned substation site on the parcel adds value.

Behind-the-Meter Power for Data Centers
Behind-the-meter power, also called behind the meter generation, is generation on the customer's side of the utility meter: gas turbines, reciprocating engines, fuel cells, batteries, or a data center built next to an existing power plant. It exists because the grid cannot deliver on the timeline developers need. More than 130 GW of generation has been proposed to serve planned data center projects in the US, over 80 percent of it gas. For a landowner, gas supply on or near the site has become a value driver in its own right.
| Technology | Time to deploy | Cost | Where it fits |
|---|---|---|---|
| Fuel cells | As little as about 90 days for modular units | Highest capital cost, about $3,000 to $4,000 per kW | Bridging power fast, sites with air permit constraints, phased campuses |
| Reciprocating engines and aeroderivative turbines | Months to about two years, subject to equipment supply | Power at about $106 to $107 per MWh, against about $86 for average industrial grid power | Bridging to grid power, or primary power at sites with pipeline gas |
| Heavy-duty and combined-cycle gas | Three to seven years | About $101 per MWh for combined cycle | Large campuses with long horizons and firm gas supply |
| Co-location at a power plant | Depends on the plant and regulators | Negotiated with the plant owner | Land next to existing generation; regulatory treatment is still being settled, and at least one high-profile arrangement had to be restructured after FERC rejected it |

Send what the utility has told you, in writing if you have it. We read the letters and studies the way a data center buyer's team will, and tell you what the site can serve, when, and what it would take to move it up a rung.
What Data Center Buyers Look for in a Site
Power comes first, but a site that fails any of the rest does not sell to a data center buyer at a data center price. The full criteria for choosing between sites are on the data center site selection guide; these are the ones that decide whether land qualifies at all.
| Factor | What buyers check | Why it matters |
|---|---|---|
| Power | Committed megawatts, energization date, voltage, redundant feeds, the tariff and its collateral | Sets what can be built, when, and at what carrying cost |
| Acreage and shape | Enough contiguous, buildable land for the building, substation, generators, cooling and setbacks, with room to phase | A 100 MW campus commonly needs tens of acres; odd shapes and easements cut usable area |
| Zoning and entitlement | Data center use by right or by special exception, height, noise and generator rules, and the local political temperature | Local opposition and moratoriums now stall projects as often as power does |
| Fiber | Distance to long-haul routes, diverse paths, carriers on or near the site | Fiber is cheaper to extend than power, but distance and diversity still cost time and money |
| Water and cooling | Water supply and discharge if the design uses it; climate for free cooling | Some counties restrict water use; closed-loop designs reduce the need |
| Physical risk | Flood zone, seismic, wind and wildfire exposure; soil and slope | Insurers, lenders and tenants all price it |
| Gas | Pipeline or lateral access for behind-the-meter generation | Increasingly a value driver on its own |
| Incentives | State sales tax exemptions and local abatements, and their current legislative status | Several states are revisiting incentives; confirm before relying on one |
Selling Land to a Data Center Developer: Land Acquisition and Deal Structures
Data center land acquisition has become one of the most active corners of commercial real estate: developers, operators and hyperscalers are buying sites years ahead of need, and data center land sales made up nearly a third of development site spending in early 2026. For a landowner, the structure of the deal matters as much as the price.
Outright sale
The simplest structure and the most common. Price depends on the power rung, the entitlements and the buyer pool; expect contingencies tied to power and zoning, and long diligence periods.
Option to purchase
The developer pays for the right to buy within a period while it works the power and permits. Lower risk for the buyer, some income and upside for the owner, and the land is tied up while it runs.
Ground lease
Long-term income while keeping ownership; common where owners do not want to sell or taxes favor it. Terms, rent resets and reversion rights matter more than the headline rent.
Joint venture
The owner contributes land, sometimes with power work already done, for an interest in the project. Highest potential upside, and the most need for independent advice on the development economics.
Data center land for sale: how sites actually trade
Most data center land for sale never appears on a public listing. Powered sites trade mainly off-market: through the land teams at the large real estate firms, through direct approaches from developers and operators, and through utilities and economic development agencies that keep lists of qualified sites. Listings that do advertise "powered land for sale" or "data center ready land" often describe proximity to transmission rather than committed capacity, so the power documents matter more than the listing. We are not a land broker; the sale itself runs through your broker and counsel. What we add is the assessment that establishes what the site is, and introductions to the developers and operators it fits.
Where landowners leave value on the table
Selling before the power work is done
The largest jumps in value come at the study and agreement rungs. An owner who can afford to take the site up the ladder often captures much of that premium instead of the buyer.
Talking to one buyer
Developers, operators and hyperscalers value the same site differently. A single unsolicited offer is rarely the market.
Long options on cheap terms
An option that ties up the land for years at a low fee, with extensions, can leave the owner holding the risk and the buyer holding the upside.
Ignoring the community
Neighbors, noise and water now decide approvals. A site with a plan for them is worth more than one that has not considered them.
How We Help
For landowners, developers and investors, the work is a written site assessment at a fixed fee: where the site sits on the power ladder, what it can realistically serve and when, the utility and tariff terms that will apply, the substation and interconnection cost and timeline, behind-the-meter options if the grid is slow, who the realistic buyers or tenants are, and what the site is worth to each. It is the usual first engagement of our data center consulting practice, typically part of a feasibility study. When the answer is to build, we advise on build to suit and powered shell structures; when it is to sell or lease to a developer, we can introduce the site to the operators and developers it fits. For buyers and lenders, the same work runs as data center due diligence.
Frequently Asked Questions
What is powered land?
Land with an electrical supply a data center can use: a utility commitment or on-site generation for a defined number of megawatts by a defined date, with a buildable connection to transmission. The strongest form has a signed electric service or facilities agreement; proximity to a power line alone does not make land powered.
How much do data centers pay for land?
It depends on the power position, the market and the entitlements. In Northern Virginia, 2026 data center land deals ran about $3.5 million to $4 million an acre, against a Loudoun County median of about $125,000, and CBRE reported pending transactions above $8 million an acre for sites with large power access. Secondary markets price far lower, but powered sites everywhere trade at a multiple of the same land without power.
How do I know if my land is suitable for a data center?
Start with power: how many megawatts the utility can deliver, when, and on what terms. Then acreage and shape, zoning and local attitudes, fiber, water, flood and seismic risk, and gas access. A written site assessment places the site on the power ladder from the utility's own documents and identifies who would build on it.
What is a data center substation?
A dedicated electrical facility that takes high-voltage power from the utility's transmission or sub-transmission system and steps it down to the medium voltage a data center distributes. Facilities above roughly 10 to 20 MW need one; large campuses connect at 138 kV or 230 kV with two independent feeds.
How much does a data center substation cost?
Core equipment typically runs $3 million to $7 million, and a 69 kV substation $6 million to $15 million. The full interconnection, including transmission lines, easements and utility charges, can run $20 million to more than $100 million depending on distance and voltage. Transformers take 60 to 120 weeks or more to arrive.
What is behind-the-meter power?
Electricity generated on the customer's side of the utility meter: gas turbines, reciprocating engines, fuel cells, batteries, or a data center built next to an existing power plant. Data centers use it when the grid cannot deliver on their timeline, usually as a bridge to utility power.
How much does behind-the-meter generation cost?
On-site gas engines and aeroderivative turbines produce power at roughly $106 to $107 per MWh and combined-cycle plants at about $101, against about $86 for average industrial grid power. Fuel cells deploy fastest but carry the highest capital cost, about $3,000 to $4,000 per kW. The premium is the price of speed.
What is large-load interconnection?
The process of connecting a very large customer, typically 20 to 75 MW and up depending on the utility, to the grid. It now usually involves studies, deposits, collateral and a large-load tariff with long minimum terms and minimum payments. Dominion's GS-5, for example, applies from 25 MW with a 14-year minimum and about $1.5 million per MW in collateral.
How long does it take to get power to a data center site?
Commonly several years. Berkeley Lab found the median time from interconnection request to operation has doubled to more than four years, and constrained markets run longer. Transformer lead times alone are 60 to 120 weeks or more.
Should I sell my land to a data center developer or lease it?
It depends on your timeline, taxes and appetite for risk. Outright sale is simplest; an option pays you while the developer works the power; a ground lease keeps ownership and provides income; a joint venture offers the most upside and the most risk. Whatever the structure, value rises sharply as the power work advances, and one unsolicited offer is rarely the market.
What is a will serve letter?
A letter from a utility stating it is able and willing to serve a property, subject to conditions. For a data center, read the capacity, the date and the conditions: a letter with no megawatts and no date usually promises study, not delivery, while one tied to a completed facilities study and an energization date is worth far more to a buyer.
What are data center power requirements?
They depend on rack count and density plus overhead. Enterprise racks draw about 5 to 15 kW, high-density racks 30 to 60 kW, and rack-scale AI systems about 120 to 140 kW each. Cooling and power conversion add overhead measured as PUE: at 1.3, 50 MW of IT load draws about 65 MW from the grid, which is the figure the utility request is sized to. New campuses are commonly planned at 100 MW and up.
What is a data center power purchase agreement?
A long-term contract to buy electricity, often from a specific generator such as a wind, solar, gas or nuclear plant, at an agreed price. Data centers use them to fix power costs and meet clean energy goals; they sit alongside the utility service agreement rather than replacing the physical connection, unless the generator is co-located behind the meter.
What is the difference between powered land and a powered shell?
Powered land is the site with its power position. A powered shell is a building on powered land, with the power and core infrastructure delivered and the interior fit-out left to the tenant. See our powered shell guide for how those deals are structured.
Do you help sell land to data center developers?
We assess the site first, in writing and at a fixed fee, so you know what it can serve and what it is worth. Where a sale, lease or joint venture is the right answer, we can introduce the site to the developers and operators it fits, and advise on the terms.
Assess Your Site
Send the location, acreage, zoning, and everything you have on power: utility letters, study results, the distance to transmission and gas. You'll hear back within 24 hours from the principal who would run the assessment, with a first read on where the site sits and whether it is worth assessing in full. If it is not a data center site, we say so before you spend anything.
Where a site sits on the power ladder, and whether the right buyers see it, decide its price more than the acreage does.
