U.S. data-center demand is growing rapidly, but projects can lose value when grid connections slip, power prices rise, permits are challenged, artificial-intelligence (AI) demand is overestimated, or equipment becomes obsolete before debt is repaid.
Investors should treat a data center as a power-and-technology project with real-estate characteristics. The underwriting must cover grid deliverability, permits, demand scenarios, construction finance, tenant concentration, cooling and water, climate hazards, insurance, and the cost of repeated technical upgrades.

Why data-center risk is unusually concentrated
Data centers require far more electricity, specialized equipment and upfront capital than ordinary commercial property. Revenue often depends on one or a few very large customers, while the building’s usefulness depends on electrical topology, fiber routes, cooling plant and backup systems that can become outdated. A delay of several months can push construction interest and equipment costs higher before any rent begins.

The U.S. Department of Energy and Lawrence Berkeley National Laboratory estimated that U.S. data centers consumed about 176 terawatt-hours (TWh) in 2023, or 4.4% of national electricity use. Their 2028 range is 325–580 TWh, equal to 6.7–12% of U.S. electricity. Those are scenarios, not guaranteed demand, but they show why local grids, regulators and communities are scrutinizing projects.

1. Power supply and grid reliability
A utility’s statement that capacity is “available” is not the same as firm power delivered to the site. Underwrite the executed interconnection agreement, queue position, required transmission and substation upgrades, construction milestones and the date firm service begins. Confirm whether the commitment is firm, curtailable or interruptible, and identify the events that allow the utility to reduce service.
Model the tariff, demand charges, transmission costs, renewable-procurement obligations and any pass-through to the tenant. A site that appears inexpensive on a per-megawatt basis can become uneconomic when demand charges or congestion increase. Check onsite generation, fuel contracts, battery storage, black-start capability and the legal right to curtail or island operations. Backup generators do not replace a dependable primary supply: fuel deliveries, emissions permits, testing limits and outage duration all matter.
The Federal Energy Regulatory Commission’s 2025 summer assessment describes tightening margins as generation retires while hyperscale load grows. In its 2024 markets release, FERC said rapidly increasing hyperscale demand combined with base-load retirements and insufficient new dispatchable generation was “not sustainable” without corrective action. Stress-test a project for delayed grid upgrades, a constrained regional market and a higher delivered-power price.
2. Permits, regulation and community acceptance
Permitting can determine whether a project exists at all. Confirm zoning and land-use approval, environmental review, water withdrawal and discharge permits, air permits for generators, noise limits, heat-rejection rules, traffic plans and construction-hour restrictions. Some jurisdictions impose renewable-power procurement, carbon reporting or efficiency requirements that change operating costs or equipment choices.
Review tax incentives for expiration, clawback and employment conditions rather than treating them as permanent revenue. Search for local litigation, ballot initiatives, public-hearing objections and agreements requiring a developer to fund roads, water infrastructure or grid improvements. The International Energy Agency reports that limited network capacity, long connection queues and slow permitting are common bottlenecks; it also warns that overestimated demand can leave utilities with stranded grid investment.
Obtain a schedule that separates approvals already issued from applications merely planned. A project with land control but no final power, water or air permits should not be valued like an operating facility.
3. Demand, AI overbuilding and market-cycle risk
AI workloads have accelerated leasing and construction plans, but demand can change faster than a multibillion-dollar facility can be built. Model slower AI adoption, more efficient models requiring fewer compute hours, customer capital-expenditure cuts, migration to newer regions and a pause in expansion phases. Lower power utilization can hurt revenue even when the lease remains signed if the contract contains usage-based charges or expansion assumptions.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The Federal Reserve’s 2025 estimate of $360 billion to $930 billion of U.S. data-center investment in 2027 illustrates how sensitive the outlook is to project-plan assumptions. The range is not a forecast of returns; it is a reminder to test multiple buildout paths instead of extrapolating one bullish case.
Use at least three operating cases: a contracted base case, a slower-demand case with delayed expansion and lower rents, and a downside case with vacancy, re-leasing costs and reduced power utilization. Test whether the asset still covers interest, maintenance capital and debt covenants in the downside case. Compare competing supply that can deliver power earlier or support newer cooling and rack-density requirements.
4. Financing, leverage and construction execution
Data centers consume capital before producing cash flow. Build a sources-and-uses model covering land, utility interconnection, substations, transformers, generators, cooling, networking, labor, insurance, taxes, contingencies and interest during construction. Separate equipment with long lead times from items that can be substituted, and require a realistic draw schedule tied to independently verified milestones.
Rank #3
Moody’s expects leverage to rise for hyperscale projects scheduled for 2026–2028. Higher leverage magnifies returns when occupancy and pricing meet plan, but it also magnifies losses when a project is delayed or refinancing becomes expensive. Model fixed and floating debt separately, include interest-rate hedging costs, and test refinancing at a higher spread and lower loan-to-value ratio.
S&P Global identifies financing conditions and cost inflation as constraints on credit quality. Require contingencies for transformer, switchgear, chip, labor and interconnection delays; define who pays for overruns; and verify contractor bonding, performance guarantees and liquidated damages. A delay can create a cash-flow gap before rent starts and may trigger covenant breaches.
5. Tenant concentration, lease terms and utilization
An anchor hyperscaler can provide strong credit and long-term visibility, yet concentration creates a single-customer failure point. Review the tenant’s financial strength, parent guarantee, security package, lease expiry, renewal options, termination rights, expansion commitments and rights to assign or sublease. Determine whether rent is fixed, indexed, power-pass-through, or tied to actual consumption.
Check take-or-pay language and the remedies available if contracted capacity is not used. A tenant may reserve power while deploying hardware more slowly, leaving the owner with underutilized electrical and cooling capacity. Model the cost and time required to re-lease the halls, including reconfiguration, new fiber, permits and downtime.
ARC identifies lease-renewal, tenant concentration and utilization as core data-center financing risks. Renewal risk rises when newer facilities offer better power density, cooling or connectivity. Do not assume a long initial term guarantees residual value if the tenant can leave at expiry and the building cannot support current equipment.

6. Technology obsolescence and retrofit cost
Data-center buildings turn over more slowly than servers, GPUs and networking equipment. Before investing, test whether the floor loading, clear height, electrical topology, busways, fiber routes and security design can support successive hardware generations. Establish the maximum rack density and the cooling method at that density, not merely the design density of the first tenant.
Estimate recurring capital for switchgear, UPS systems, chillers, heat exchangers, liquid-cooling distribution, controls and network upgrades. Ask which components can be replaced without shutting down occupied halls. ARC calls obsolescence a distinctive data-center financing risk; reliable power and fiber, efficient cooling and adequate backup reduce vulnerability but do not eliminate it. S&P Global likewise warns that obsolescence can lower residual values.
Use a technical reserve in the valuation. A well-located building may still need expensive retrofits to serve high-density AI racks, and some older halls may be economically stranded rather than upgraded.
7. Water, cooling, climate and insurance
Cooling performance is an operating and resilience issue. Map the water source, withdrawal volume, discharge route, permit limits, drought restrictions and competing municipal or industrial demand. Compare air cooling, evaporative systems, chilled water and direct-to-chip liquid cooling for efficiency, water use, maintenance and failure modes.
Design conditions should reflect future heat waves, not only historical averages. Review flood maps, wildfire exposure, extreme wind, hail, winter storms, seismic risk and smoke. Confirm elevation, drainage, fire suppression, redundant cooling loops, spare parts, generator autonomy and recovery procedures. Schneider Electric’s 2026 climate analysis links physical hazards to cooling stress, physical damage, business interruption, transition risk and supply-chain exposure.
Best Value
Obtain insurance quotations before closing. Zurich’s 2026 whitepaper highlights tightening insurance capacity, severe weather, energy and water constraints, resilience requirements and evolving regulation. Compare limits, deductibles, waiting periods, service-interruption coverage, contingent business interruption, equipment breakdown and exclusions for flood, wildfire, cyber events or utility failure. A policy that excludes the most likely outage may not protect debt service.

- Verify power. Obtain the interconnection agreement, queue evidence, upgrade scope, firm-service date, tariff, curtailment terms and backup-fuel plan. Have an engineer confirm that the substation and internal distribution match the promised load.
- Build a permitting register. List every zoning, environmental, water, air, noise and generator approval, showing status, responsible party, appeal period and long-stop date.
- Reconcile demand with contracts. Tie each megawatt and expansion phase to a signed lease, credit support and realistic deployment schedule. Model vacancy and re-leasing costs rather than assigning zero downtime.
- Run downside financial cases. Delay energization, increase construction cost, raise interest rates, lower utilization and extend lease-up. Check debt-service coverage, covenants, reserves and refinancing proceeds in each case.
- Commission technical diligence. Test rack-density headroom, cooling redundancy, fiber diversity, floor loading, maintainability and the cost of adding liquid cooling or new electrical gear.
- Map physical and insurance exposure. Quantify water stress, flood and wildfire risk, expected outage duration, policy exclusions and the premium impact of higher deductibles.
- Set exit assumptions. Compare the likely buyer universe, remaining lease term, required retrofit capital, competing supply and market liquidity. Use a lower residual value when technology or tenant concentration is high.
Comparing two data-center investments
Use the same assumptions and evidence standard for every opportunity. The following decision axes prevent a low purchase price from masking execution or obsolescence risk.
| Comparison axis | Questions to answer |
|---|---|
| Power | Which site has a firm delivery date, lower delivered cost, stronger queue position and less curtailment? |
| Permits | Are approvals final, appeal-proof and sufficient for generators, water and heat rejection? |
| Tenants | How strong is credit, how concentrated is revenue, and what happens at renewal or termination? |
| Lease protection | Are rents fixed or usage-based, and are take-or-pay, guarantees and power pass-throughs enforceable? |
| Cooling and water | Can the site operate through drought and heat waves, and can it support liquid cooling? |
| Technology flexibility | What rack density, fiber diversity and electrical expansion are available without major shutdowns? |
| Construction | Are schedule, contingencies, contractor obligations and long-lead equipment verified? |
| Capital structure | How much leverage exists, when does debt mature, and how much covenant headroom remains? |
| Climate and insurance | Are hazards insurable at acceptable limits, deductibles and waiting periods? |
| Exit liquidity | How many buyers could acquire the asset without a large retrofit or tenant replacement? |
What the risks mean for different investors
The appropriate conclusion depends on the country, power market, tax regime and investment vehicle. Direct owners and developers bear construction, permits, utility and retrofit risk. Equity in a data-center real-estate vehicle may diversify individual assets but still carry tenant, leverage and valuation exposure. Debt investors focus on collateral value, lease durability, coverage, guarantees and refinancing. Publicly traded vehicles add interest-rate and market-liquidity risk that can move independently of property operations.
Recommended Free Tools
Do not transfer a U.S. power or permitting assumption to another country without rebuilding the analysis. Capacity markets, interconnection rules, taxes, water rights, currency and data-sovereignty requirements vary by jurisdiction. A quantified recommendation requires those inputs and the investor’s position in the capital stack.
