1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsTo assess whether a local grid can serve a data center, compare the facility’s expected peak demand in megawatts (MW) with a capacity assessment for the utility and grid infrastructure that would supply it. Compare annual energy use in megawatt-hours (MWh) or terawatt-hours (TWh) separately: energy measures electricity used over time, while MW measures power at a moment or peak interval. A national electricity-use share cannot establish whether a particular site can be connected.
Start with the location and the grid connection
Identify the data center’s point of interconnection and the infrastructure behind it: the serving utility, relevant distribution feeder or substation, transmission provider or planning area, and regional grid operator where applicable. Distribution and transmission constraints are different, and power available elsewhere is not necessarily deliverable to the site.

This local detail matters even when regional or national supply appears ample. The International Energy Agency (IEA) says local impacts can be more pronounced than global totals suggest and identifies siting where grid capacity is available as one way to mitigate them. IEA, Energy and AI — Executive summary (2025).

For a capacity comparison, use the data center’s requested or expected maximum coincident demand at the point of interconnection, expressed in MW. “Coincident” means the facility’s demand during the relevant system peak, rather than its separate maximum at some other time. Record the forecast year and whether the figure includes cooling and other facility loads.

Label the project’s status as well as its size: proposed, requested, approved, under construction, energized, or forecast. These are not interchangeable measures of existing load. Forecasts depend on which planned facilities proceed and when. FERC notes that project size and timing matter to planning, and that regional forecasts may use coincident or non-coincident peak conventions; check which convention the local assessment uses. FERC, 2025 State of the Markets (published 2026).
Compare like with like
- Power versus energy: Compare peak demand in MW with a relevant grid power or capacity assessment. Annual consumption in MWh or TWh describes energy over a period and does not answer whether the grid can supply a peak load.
- Same boundary and time horizon: Match the demand estimate and grid assessment to the same site, grid layer, forecast year, and peak definition.
- Deliverable capacity, not just a nameplate total: Installed or stated capacity does not by itself show what can be delivered at the site under network and reliability conditions.
- Keep project status visible: Do not add proposed or requested load to energized demand without identifying it as forecast or pipeline demand.
A simple ratio of facility peak demand to a clearly defined local capacity figure can help convey scale, but it is only a screen. It does not show that service is available or prove that the network can meet reliability requirements. That conclusion requires a utility impact assessment or interconnection study.

What national statistics can—and cannot—tell you
National and global figures help explain why data center demand is receiving attention, but they are context rather than local capacity measures.

| Measure | Reported figure | What it means for a local comparison |
|---|---|---|
| United States annual electricity use | DOE’s December 20, 2024 summary of the Lawrence Berkeley National Laboratory report says data centers used 176 TWh in 2023, or 4.4% of total U.S. electricity. The report estimated 325–580 TWh by 2028, about 6.7%–12% of U.S. electricity. | National annual energy use and estimates; not the available MW at a particular site. DOE (December 20, 2024). |
| U.S. in-service data center capacity | FERC staff reported more than 50 GW in service at the end of 2025. Average facility size for sites entering service rose from 25 MW in 2020 to almost 80 MW in 2025. | National capacity and facility-scale context; neither figure is the capacity available on a local feeder or transmission path. FERC, 2025 State of the Markets (published 2026). |
| Global annual electricity use | The IEA estimated data centers consumed 415 TWh, around 1.5% of world electricity, in 2024. Its base case projects around 945 TWh in 2030. | Global observation and scenario projection; neither determines local interconnection feasibility. IEA (2025). |
Account for onsite supply and flexibility carefully
Onsite generation, batteries, or flexible operations can change how much power a facility draws from the grid and when it draws it. Do not simply subtract their nameplate capacity from the data center’s peak demand. Document each resource’s location, expected contribution, availability during the relevant peak, and whether it is firm or conditional. An interconnection or planning assessment should make clear how these resources are treated.

What to request before judging whether the grid can handle a project
A defensible local answer requires location-specific information; national reports do not establish a capacity result for an unnamed site. Ask the utility or grid operator for the relevant interconnection study, distribution planning information, transmission planning assessment, or other local capacity analysis. For a useful comparison, assemble:
- The site’s point of interconnection and serving utility.
- Requested or forecast peak demand in MW, its status, forecast year, and peak convention.
- Confirmation of which facility loads are included, including cooling.
- The local assessment’s capacity measure, scope, time horizon, and reliability assumptions.
- Identified network upgrades and their timing, if any.
- Documented onsite supply, storage, and operational flexibility, including whether each is firm or conditional.
When comparing multiple facilities or grid areas, keep the geographic boundary and forecast year constant. Compare point-of-interconnection demand, project status and in-service date, coincident peak contribution, load coverage, local study findings, required upgrades, and documented flexibility. The IEA says around 20% of planned data center projects could be at risk of delays if grid risks are not addressed; it also reports that new transmission lines can take four to eight years to build in advanced economies. These are conditional, broad findings—not a schedule prediction for any individual project. IEA (2025).
