Does a nearby substation prove that power is available?
No. Confirm the proposed connection, usable site-specific capacity, required upgrades, service conditions, and energization milestones with the serving utility.
Power diligence guide
Powered land is land supported by a documented, site-specific path to electric service, including capacity, timing, conditions, and cost. A nearby substation identifies infrastructure to investigate; it does not establish that the site can receive the required megawatts by the required date.

| Question | Land near a substation | A supported powered-land claim |
|---|---|---|
| Substation proximity | Shows a nearby physical asset; ownership and a feasible connection remain to be checked. | Identifies the proposed service path, point of connection, and required land rights. |
| Available capacity | Does not show unused, allocated, or deliverable capacity. | States site-specific MW, service conditions, and the evidence supporting each phase. |
| Will-serve letter | A map or seller statement is not a utility letter. | Includes the actual letter or agreement, its conditions, and whether capacity is reserved. |
| Timing | Distance alone supplies no energization date. | Separates initial and full-load dates, with named studies, upgrades, and dependencies. |
“Powered” is a description to substantiate, not a universal certification. Check deliverable power against the actual load and operating requirements.
Loudoun County reports that some approved data center locations lack adequate substation and distribution infrastructure. Land-use approval and an attractive electrical map therefore answer different diligence questions.
Start with the powered land and substation definitions, then use the capacity-letter checklist.
No. Confirm the proposed connection, usable site-specific capacity, required upgrades, service conditions, and energization milestones with the serving utility.
No. A site can have a documented service pathway while studies, agreements, equipment, and construction remain outstanding. State its actual status.
Read the actual document. Ask the issuer what capacity, if any, is reserved, for whom, until when, and subject to which conditions.
Verify utility service demand separately from critical IT load, including cooling and other facility demand, the phased ramp, and any operating restrictions.
Resolve the evidence for capacity and timing, remaining cost exposure, service rights, and conditions that could prevent the proposed development from proceeding.
