Data Center Development, Answered
Data Center Development FAQ
A plain-English question bank on data center land, power, brownfields, water, fiber, and investment — each answer self-contained. For deeper treatment, follow the links to the full guides.
Land & Site
What is data center land?
Real estate suitable for building a data center — most importantly, land that can be served with large amounts of reliable electrical power, plus adequate acreage, buildable topography, low flood risk, fiber, water, and appropriate zoning. The defining feature is power availability, which is why it overlaps with powered land. See Data Center Land Requirements.
How much land does a 100 MW data center require?
Roughly 20 to over 100 acres depending on design and density, accounting for buildings, substation, generators, cooling, setbacks, and expansion. Lower-density designs use more land; dense multi-story designs use less.
What makes a site shovel ready?
Entitlements, zoning, environmental clearances, and utility commitments in place so construction can start with minimal delay. Adding secured electrical capacity makes it shovel-ready powered land — the most valuable raw input in the industry.
Power & the Grid
How much power does a data center need?
From under 1 MW for small edge or enterprise sites to 50 to 150 MW for a hyperscale building or phase, up to 500 MW to over 1 GW for large AI and cloud mega-campuses. See How Much Power Does a Data Center Need?
What is a megawatt?
One million watts of power. Data center capacity is measured in megawatts of critical IT load — the power available to the computing equipment — rather than in square feet.
Why does power matter more than land for data centers?
Land is abundant and cheap; deliverable, reliable, near-term power is scarce, expensive, and slow. A site can be graded in months, but a new interconnection and substation can take years. So value and competitive advantage migrate to whoever can deliver megawatts.
What is an interconnection queue?
The line of projects waiting for the studies and approvals needed to connect new load or generation to the grid. Queues have become heavily backlogged, with multi-year waits common, making queue position — or the ability to avoid it — a critical variable.
What is a substation?
Electrical infrastructure that transforms high-voltage transmission power down to usable levels and serves as the connection point to the grid. An on-site or nearby substation with available capacity is one of the most valuable features a site can have.
What is behind-the-meter generation?
Power produced on-site, on the customer's side of the utility meter — natural gas turbines, fuel cells, solar, or future small modular reactors — letting a data center come online without waiting for grid interconnection.
Brownfields
Can a brownfield become a data center?
Yes. Brownfields often arrive with existing power infrastructure, industrial zoning, utility connections, and large contiguous land. The trade-off is potential remediation, demolition, and verifying the usable capacity of existing infrastructure. See Brownfield & Coal Plant Conversion.
Why are retired coal plants valuable for data centers?
When a coal plant retires, its grid interconnection, switchyard, and high-voltage ties remain, along with cooling water, rail, and large acreage. A data center can import large load through that existing interconnection, saving years and large capital versus a greenfield.
Facilities, Water & Fiber
What is colocation?
A model where a provider builds and operates the data center and leases space and power to customers. Retail colocation serves many tenants renting racks or cages; wholesale colocation leases large dedicated blocks of power to single large customers.
What is a hyperscale data center?
A very large facility built by or for major cloud and AI operators, designed for massive, standardized, rapidly scalable capacity, commonly from tens of megawatts into the hundreds or beyond.
What are N+1 and 2N redundancy?
N+1 means the components needed to carry the load plus one spare, so a single failure does not interrupt operations. 2N means fully duplicating the system — two complete independent sets — so an entire side can fail and operations continue. 2N is more expensive but more fault-tolerant.
How much water does a data center use?
It depends on cooling design. Evaporative cooling can use large volumes; air-cooled, closed-loop liquid, and immersion cooling can sharply reduce or nearly eliminate water use, often by trading some energy efficiency for water savings. See Data Center Water & Cooling.
What is dark fiber?
Fiber-optic cable that has been installed but not yet lit with active equipment — spare capacity in the ground that lets an operator light its own high-capacity connections quickly. See Data Center Fiber & Connectivity.
Economics & Investment
What is a development spread?
The gap between yield on cost (stabilized NOI divided by total development cost) and the market exit cap rate. That spread is the development profit, capitalized into value, and wide spreads from scarce powered land are drawing capital into the sector. See Data Center Economics & Underwriting.
How can a landowner tell if their land is good for a data center?
Start with power: how close is high-voltage transmission and a substation with available capacity, and what does the serving utility say about available load. Then acreage and contiguity, topography, flood risk, environmental condition, fiber, water, and zoning. Land near transmission, a substation, or a brownfield with existing power is the strongest candidate.
How do you determine the highest and best use of an obsolete industrial site?
Run four tests in order: legally permissible (zoning, deed restrictions, environmental status), physically possible (acreage, topography, flood risk, structural condition), financially feasible (what each use costs to deliver versus what the market pays), and maximally productive (which feasible use yields the highest residual land value). For obsolete factories the answer is often not re-tenanting the building — it is powered land for a data center, an Industrial Outdoor Storage (IOS) or Enclosed Industrial Outdoor Storage (EIOS) yard, or land redevelopment, because the land plus infrastructure is worth more than the aging structure.
What are the signs my industrial property is worth more than its current use?
Watch for these ten signals: (1) proximity to high-voltage transmission or a substation with available capacity; (2) a large or upgradable electrical service; (3) 10+ contiguous, mostly flat, buildable acres; (4) active or dormant rail access; (5) nearby fiber routes; (6) water and sewer capacity; (7) heavy-industrial or flexible zoning; (8) a functionally obsolete building on a still-valuable site; (9) location in the path of growth, near highways or a port; and (10) active buyers — data center developers, IOS/EIOS operators, or institutional investors — in your submarket. Several together usually mean the land outvalues the current operation.
How do you sell an industrial campus to institutional buyers?
Use a seller playbook: (1) define the real product — powered land, redevelopment site, or stabilized asset; (2) assemble a diligence package (survey, title, environmental, utility will-serve letters, power capacity, zoning); (3) quantify and document available power, the primary value driver; (4) resolve or disclose environmental and brownfield status; (5) position the highest and best use (data center, IOS, EIOS, logistics); (6) market to the right institutional buyers — funds, developers, REITs, and their brokers — not the local retail pool; and (7) structure terms (option, phased close, ground lease) that fit institutional underwriting. Clean diligence and a documented power story are what move institutional pricing.
