How Many Acres Does a Data Center Need?

How many acres does a data center need? Roughly 10-40 acres for a 5-20 MW enterprise or colocation facility, 100-300 acres for a 50-100+ MW hyperscale campus, and 875-1,400 acres for the 1-2.5 GW AI campuses that broke ground in 2025 and 2026 ([1]; [2]; [3]). Notably, a 100 MW liquid-cooled AI campus fits on 44-100 acres at the densities in Table 1, or 200-500 acres under the older planning rule of 2-5 acres per MW ([4]; [1]). The question therefore has no single number; it has a density, and the density is set by rack power, cooling type, on-site generation, setbacks, and the substation.

The sections below give the acreage and MW of 17 named campuses with MW per acre computed for each, rule-of-thumb acres per MW by design type, dated land prices per acre, the criteria buyers actually rank, and what a landowner should expect from an option agreement.

How many acres do real data center campuses use?

Table 1 lists announced or built campuses with disclosed acreage and power. Specifically, mW per acre is computed from the two disclosed figures; where a campus includes on-site generation inside the acreage, the note says so. In particular, all figures are as of the source date shown.

The computed range across the 16 campuses with disclosed power is 0.33-3.53 MW per acre, or 0.28-3.1 acres per MW. For example, the gigawatt-class AI campuses announced in 2025-2026 (Stargate Abilene, Hyperion, Rainier, Frontier, Caprock, Jupiter) cluster tightly at 1.17-1.83 MW per acre, which is 0.55-0.86 acres per MW. The outliers explain the spread: Switch’s Citadel was master-planned in 2017 with 7.2 million sq ft for 650 MW, a legacy density ([21]), while QTS’s Hillsboro 2 is a multistory urban-edge site with no room for expansion or generation ([23]).

Two flagship sites are omitted from the density range on purpose. Microsoft disclosed 315 acres and 1.2 million sq ft for Fairwater but did not publish a MW figure ([26]), and Google bought 1,185 acres in Council Bluffs in 2007 and later added a second 1,000-acre campus with 2.9 million sq ft, without disclosing site power ([27]; [28]). xAI’s Colossus shows the brownfield alternative: the first cluster went into a 785,000 sq ft former Electrolux plant with 150 MW of TVA-approved grid power, later raised to 250 MW ([29])), and Colossus 2 added a 1 million sq ft warehouse plus adjacent parcels totaling about 100 acres ([30]).

How many acres per MW by design type

Acreage per MW is a function of building density, cooling, and what else sits inside the fence. Importantly, table 2 assembles published rules of thumb and measured footprints for each component. As a result, multiply the components that apply to a given site; do not use a single number.

Worked example: 100 MW with and without on-site generation

Using the Table 2 components, a 100 MW liquid-cooled campus at the 2025-2026 observed density needs 55-86 acres of buildings, yards, and cooling plant. By contrast, a Langan-scale substation adds roughly 17 acres per 100 MW ([38]). In addition, bridging or primary gas turbines add about 20 acres per 100 MW ([32]), which is why Stargate Abilene planned 360 MW of on-site turbines inside its 875 acres ([5]) and Meta is deploying 366 MW of modular gas units at El Paso ([42]).

Solar changes the order of magnitude. U.S. For instance, utility-scale PV ran at a 23.2% annual capacity factor in 2024 ([43]), so supplying 100 MW of continuous load on an annual energy basis requires about 431 MWac of nameplate, before storage losses. Similarly, at NREL’s 5-7 acres per MWac ([33]), that is roughly 2,150-3,000 acres of panels, a 25-35x multiplier on the data center’s own footprint. This is why Microsoft’s Fairwater solar sits 100+ miles away in Portage County rather than on the 315-acre campus ([26]), and why on-site solar on a data center campus is a supplement, not a supply.

Setbacks can consume most of a small parcel

Setbacks are the reason small parcels fail. Notably, a 40-acre square parcel has sides of 1,320 ft; applying Spotsylvania’s 400 ft residential setback on all four sides leaves a 520 ft by 520 ft building envelope of 6.2 acres, 16% of the parcel ([39]). Specifically, james City County’s 1,000 ft separation from dwellings ([40]) eliminates that parcel entirely if any house sits within 1,000 ft of the property line. Cushman & Wakefield’s data shows the market responding: the average data center land transaction reached 224 acres in 2024, up 144% since 2022, with 190 acres in established markets and 340 acres in emerging ones ([44]).

How do data centers choose land?

Buyers rank power first and everything else second. In particular, enverus summarizes the hierarchy as “power, price, land,” notes that hyperscale facilities now need 100+ MW, and puts electricity at 25-60% of operating cost ([45]). For example, cBRE’s 2026 site-selection framework leads with power availability and scalability, then power cost, connectivity and latency, site availability and planning certainty, clustering, and sustainability ([46]). Importantly, a civil engineering firm’s weighted scorecard gives power 25%, fiber 20%, water 15%, land size and geotechnical 15%, natural hazard risk 10%, zoning 10%, and tax incentives 5% ([47]).

Power availability and interconnection timeline

The interconnection timeline dominates because it is the only variable a developer cannot buy. Data centers are built in 18-24 months, while new high-voltage transmission takes 7-10 years and generation projects wait 4-5 years in interconnection queues ([48]). As a result, the same analysis cites 55 months from interconnection request to commercial operation for generation reaching service in 2024 ([48]). By contrast, a parcel with an executed large-load study and a substation path is a different asset from a parcel that merely sits under a transmission line. In addition, land counsel put it directly: a 40-acre tract with a realistic large-load power path is worth more than 100 acres without one ([49]).

Fiber, water, zoning, geotechnical, and hazards

JLL’s screening guidance calls for three to four redundant fiber providers and frames the modern demand curve as 100 MW or more for new developments, 200-300 MW in outer-suburban locations, and 500 MW to 1 GW for rural AI campuses that “require 500-800 acres” and multiple substations ([50]). Ramboll’s criteria add that hyperscale cloud sites typically exceed 100 MW while AI sites may require 200 MW or more, with some clients seeking 600 MW ([51]). For instance, wetlands, endangered species, floodplain, soils, and stormwater come next as physical feasibility screens, followed by road access, drainage, water, wastewater, and fiber ([49]). Similarly, a detailed diligence sequence is covered in data center site selection due diligence.

Zoning determines the calendar. Land already zoned heavy industrial can close in months, while agricultural or general commercial land needs a rezoning or conditional-use process that adds six months to well over a year, longer if a public hearing draws opposition ([52]). Community posture is now a measurable variable: at least 75 projects worth about $130 billion were blocked or delayed in the first quarter of 2026 alone ([53]), after $152 billion was blocked or delayed across 2025 ([54]). The U.S. Notably, data Center Moratorium Tracker logs which jurisdictions have active moratoria or restrictive ordinances.

What is data center land cost per acre?

Land is a small share of total project cost but the most variable line item. Specifically, the weighted average U.S. In particular, data center land price through October 2024 was $5.59 per sq ft, or about $244,000 per acre, down $39,000 per acre year over year as buyers moved to larger, cheaper rural parcels; parcels of 50 acres or more rose 23% to $5.40 per sq ft over the same period ([44]). For example, table 3 lists dated transactions and market ranges.

The spread is three orders of magnitude: $8,156 per acre for Meta’s El Paso parcel versus roughly $6.3 million per acre in Loudoun County. Importantly, the Cushman & Wakefield series shows the same pattern nationally, with the Chicago median at 13 times Iowa’s ([44]). Because land in Northern Virginia trades at 25-50 times the national average, the gigawatt campuses of 2025-2026 went to Abilene, Richland Parish, New Carlisle, Shackelford County, and Doña Ana County, where 1,000+ acre assemblages were possible.

How to sell your land to a data center

Developers screen parcels in a fixed order, and a landowner who understands the order negotiates better. Land counsel ranks the drivers as: power path first, entitlement posture second, physical feasibility third (wetlands, species, floodplain, soils, stormwater), infrastructure fourth (access, drainage, water, wastewater, fiber), then parcel logic and “dealability” ([49]). As a result, broker screens are the same: proximity to a transmission substation, industrial or flexible zoning, contiguous acreage of 20+ acres (100+ for hyperscale), flat ground outside the flood zone, and a utility able to serve ([52]).

The option agreement

Nearly every data center land deal starts as an option, not a sale. By contrast, developers typically ask for twelve months and broad termination rights; the negotiable terms are a refundable initial period, paid extensions, milestone triggers, staged deposits that harden over time, option fees, and escalating purchase prices ([49]). In addition, agricultural law counsel report that site consultants ask for a non-disclosure agreement immediately and then a three-year purchase option with unrestricted access for soil borings and environmental testing ([58]). For instance, option agreements routinely run 20 or more pages and the diligence waiting period can stretch to years ([59]).

The Meta El Paso transaction shows the structure at hyperscale: a year-long inspection period with extensions beginning April 2022, closing in December 2023, a price set by an independent CBRE appraisal, and a five-year deadline to develop the site ([13]). Similarly, buyers use that period for title and survey, Phase I environmental, geotechnical borings, a utility power study, wetlands and floodplain delineation, and zoning review ([60]).

Red flags for landowners

Three patterns separate real buyers from land speculators. First, an option with no fee, no milestones, and unlimited free extensions transfers all timing risk to the seller ([49]). Second, unrestricted testing access without a restoration and indemnity clause leaves the owner with open bore holes and crop damage if the deal dies ([58]). Third, a buyer who cannot describe the power path is usually optioning land to flip to someone who can; the executed utility study, not the letter of intent, is the evidence that a buyer is real ([49]).

How many acres does an AI data center need, and why is the math different?

AI changes the acreage math in two opposite directions: buildings get denser, and campuses get bigger. Notably, Uptime Institute’s 2024 survey put average rack density below 8 kW, with most facilities reporting no racks above 30 kW ([61]), and its 2025 survey shows densities rising slowly through growth in the 10-30 kW range ([62]). Specifically, a single NVIDIA GB200 NVL72 rack draws 120 kW ([63]), and AI campuses are planned at 50-100+ kW per rack and 300-1,000+ MW per campus ([1]).

Denser racks mean fewer square feet per MW. In particular, a 2018 Tier III design study in Ashburn used 200 W per sq ft as its baseline ([64]). The liquid-cooled campuses in Table 1 run higher: Vantage Frontier’s 3.7 million sq ft for 1,400 MW is about 378 W per sq ft ([10]), Aligned Caprock’s 1.65 million sq ft for 540 MW is about 327 W per sq ft ([12]), and Stargate Abilene’s roughly 4 million sq ft for 1,200 MW is about 300 W per sq ft ([2]). For example, switch’s Citadel plan of 7.2 million sq ft for 650 MW, about 90 W per sq ft, marks the legacy end ([21]). Importantly, cooling design drives this; see liquid cooling for AI.

The campus still grows because the power system moves on site. As a result, stargate’s 875 acres carry 360 MW of gas turbines ([5]); Project Jupiter’s 1,400 acres carry gas plants, batteries, and a desalination plant ([3]); Project Jade’s 1,375-acre PUD was written to allow a 1.8 GW power plant alongside the data centers ([17]). By contrast, fermi America’s 5,800 acres are sized for 11 GW of nuclear, gas, and solar generation feeding 18 million sq ft of data centers ([25]). In addition, the behind-the-meter tradeoffs are covered in behind-the-meter AI power.

How moratoria and zoning reshape parcel selection

Local ordinances now set the effective acreage as much as engineering does. For instance, spotsylvania’s December 2025 standards impose a 300 ft vegetated buffer, a 400 ft setback from residences, and a 75 ft height cap ([39]); Albemarle County has proposed 200 ft and 500 ft setbacks ([65]); James City County requires 1,000 ft from dwellings ([40]). Similarly, each of these rules pushes developers toward larger parcels with interior building envelopes, or toward jurisdictions without them.

The result is the geography visible in Table 1: gigawatt campuses on 875-5,800 acres in Texas, Louisiana, Indiana, New Mexico, Nevada, and Wyoming, while Northern Virginia deals shrink to 42-189 acres at $3.5-6.3 million per acre ([55]). Notably, before optioning any parcel, check the jurisdiction against the Data Center Moratorium Tracker and the general data center land requirements checklist.

How SAVRN builds for this

SAVRN’s AI factory design treats acreage as an output of power and cooling decisions rather than an input. The compute block, the Atom, is factory-built and liquid-cooled, which places it at the dense end of the Table 1 range rather than the 2-5 acres per MW planning rule. The power system, the Electron family, is behind-the-meter generation sized to the compute block, which removes the 7-10 year transmission timeline from the critical path ([48]) and adds a known generation footprint instead of an unknown interconnection date. Specifically, the design is water-free, which eliminates the water-rights and wastewater screens that eliminate many rural parcels.

Because hosts are universities, cities, and communities, parcel selection starts from land the host already controls, often industrial or institutional acreage with existing zoning, rather than from agricultural land that needs a rezoning. In particular, the self-powered AI data center page describes the block-level power architecture, behind-the-meter AI power covers the generation tradeoffs, and the Data Center Moratorium Tracker is maintained as a public screen for jurisdictional risk. For example, the site selection due diligence article lists the studies SAVRN runs before a site is committed.
