Data centers can be built faster than the infrastructure needed to power them. A building may be ready while its grid connection, substation work, transmission upgrades, equipment deliveries, or approvals are not. JLL Research reports that 57% of data center projects experienced a construction delay of at least three months in 2025; that figure describes the projects covered by its industry research, not every market or a single cause of delay. The practical challenge is coordinating interdependent schedules, each with its own local constraints.
Why can a data center finish before its power is ready?
Building construction is only one part of delivery. A project also needs a viable connection to the electric system, enough capacity at the relevant location, and any required network upgrades. Those works may involve utility studies, substations, transmission lines, equipment procurement, permitting, and coordination with other planned loads.
The timing gap can be substantial. The International Energy Agency (IEA) gives broad global ranges of 1–3 years to build a data center and 5–15 years to plan, permit, and complete new grid infrastructure. These are context-setting ranges, not a schedule prediction for a particular site or utility. [IEA, Electricity 2026: Grids]
JLL Research estimates an average global build time of 18 months for a 50 MW data center and says developers pre-order selected materials as much as 24 months in advance. The advance orders reflect the need to manage procurement alongside construction, not a guarantee that every component will arrive on time. [JLL 2026 Global Data Center Outlook]

Grid connection and capacity
A nearby power line does not by itself prove that a site can receive the required load. The relevant questions are whether the local system has capacity, what upgrades a utility study identifies, who will deliver them, and when they can be energized. A project can face a connection queue or depend on work elsewhere on the network. The IEA says more than 2,500 GW of renewable, large-load, and storage projects were stalled in grid queues worldwide; that is an indicative 2025 figure, and queue totals change over time. [IEA, Electricity 2026: Grids]
Electrical and cooling equipment
Transformers, switchgear, generators, UPS systems and batteries, chillers, and other cooling equipment are not interchangeable procurement items. Their suppliers, specifications, and delivery schedules differ, so a single average cannot predict the lead time of a critical component. JLL reports average data center equipment lead times of 33 weeks globally—50% above pre-2020 levels—and 42 weeks in the U.S.—83% above 2019 levels. These are overall averages, not promises for a particular item or project. JLL also says developers at scale hold 6–12 months of strategic inventory for critical components. [JLL 2026 Global Data Center Outlook]
For a separate U.S. supply-chain indicator, the Department of Energy’s Office of Electricity reports that distribution-transformer lead times rose from 3–6 months in 2019 to 12–30 months in 2023. The 2023 figure is the latest year stated in that series; it is not a 2026 reading and should not be treated as the lead time for all data center equipment.
Skilled labor and coordination
Expanding projects compete for skilled trades and supply-chain capacity. JLL identifies limited skilled-trade availability alongside extended equipment lead times. Labor availability can therefore affect both the pace of on-site work and the installation or commissioning sequence, but the available figures do not establish a single labor-shortage rate applicable across markets.
Permits, sustainability rules, and community support
Approvals and requirements depend on the jurisdiction and the site. Local rules, environmental review, utility processes, and community concerns may shape a project’s sequence or design; there is no single global permitting duration that can be applied to every data center. JLL identifies community support as the second site-selection criterion after speed to power, underscoring that a technically viable location is not automatically an easy one to develop. [JLL 2026 Global Data Center Outlook]
How should teams test whether a schedule is realistic?
Start with the date the facility must be energized, then work backward through the specific dependencies that control that date. A general grid timeline or national equipment average is useful context, but neither substitutes for project-specific confirmation.
- Confirm the power requirement. Define the initial and ultimate load, the ramp-up schedule, and any operational flexibility. Check that the utility and project teams are using the same assumptions.
- Obtain the project-specific connection picture. Review the utility study, identified network upgrades, responsibility for each work package, approval status, and realistic completion dates. Distinguish a proposed connection date from a committed one.
- Build a component-level procurement schedule. Track each critical transformer, switchgear package, generator, UPS or battery system, and cooling component against its required-on-site date. Identify specification decisions, supplier dependencies, and commissioning needs rather than relying on one blended lead-time figure.
- Map approvals and site dependencies. Track permits, environmental and sustainability requirements, utility approvals, and community engagement by jurisdiction. Make dependencies visible in the same schedule as civil, electrical, and mechanical work.
- Stress-test the critical path. Check what happens if a grid upgrade, key component, or approval slips. Keep schedule contingency tied to named risks and responsible parties, and update it when supplier or utility milestones change.
Can alternatives get a project connected sooner?
Potential approaches can improve access or reduce waiting in some circumstances, but they do not erase local system limits. The choice depends on site-specific studies, operating requirements, approvals, equipment availability, and who bears the cost.
| Approach | Potential benefit | Trade-off or condition |
|---|---|---|
| Plan the connection and upgrades early | Reveals utility work and approval dependencies before they collide with building milestones. | Early planning does not make a long-lead upgrade or approval complete sooner by itself. |
| Non-firm connection | May provide access using available capacity sooner than waiting for a fully firm connection. | The operator may have to reduce or interrupt consumption at specified times; this is not equivalent to uninterrupted firm power. |
| Grid-enhancing technologies | Can help use existing grid capacity more efficiently in suitable locations. | Benefits depend on system-specific constraints and study; these technologies do not necessarily remove the need for new grid infrastructure. |
| Change the site or operating plan | A different location, phased load, or more flexible operating profile may align better with available capacity and delivery timing. | Requires reassessing power availability, equipment and construction plans, local approvals, community acceptance, and total cost. |
The IEA identifies non-firm connections and grid-enhancing technologies as possible ways to make better use of existing capacity, while emphasizing that hosting capacity depends on system-specific conditions. A 2026 Lawrence Berkeley National Laboratory review groups more than 40 large-load connection-acceleration options across forecasting, interconnection, resource planning and procurement, markets and operations, and cost allocation and ratemaking. The breadth of those categories matters: a solution may require changes to planning, procurement, operations, or payment rules—not just a new piece of equipment.

What do construction cost figures include?
Cost comparisons are meaningful only when they use the same project scope and design. JLL’s global averages below cover shell and core for a single-tenant, 50 MW, air-cooled facility. They exclude land and active IT equipment; the 2026 figure is a forecast, not a final observed cost.
| Year | JLL global average shell-and-core cost | Status |
|---|---|---|
| 2020 | $7.7 million per MW | Reported average |
| 2025 | $10.7 million per MW | Reported average |
| 2026 | $11.3 million per MW | Forecast |
Under JLL’s stated assumptions, liquid-cooled facilities carry a 10% cost premium; multistory facilities in the Americas add 20%. Those design-specific figures should not be combined mechanically with the average above to estimate a particular build. JLL separately says tenant AI fit-out can cost as much as $25 million per MW, a different scope from shell and core. Compare project size, market, cooling design, building form, tenant fit-out, land, and active IT equipment before treating two cost figures as comparable. [JLL 2026 Global Data Center Outlook]
What does the wider grid investment outlook mean for developers?
The IEA estimates that annual grid investment needs to increase by approximately 50% by 2030 from a then-current $400 billion. This is a requirement estimate, not money already invested or a guarantee that upgrades will be available for a given project. For developers, the useful takeaway is to treat grid capacity and delivery dates as core site-selection and schedule inputs, and to verify them directly with the relevant utility and authorities.
