How it generally works
When a large new load requires grid upgrades — a new substation, transmission extension, reconductoring — the interconnection study identifies what is needed and what it costs. The requesting party typically funds it, often through a contribution in aid of construction or a comparable mechanism, with the specifics varying by utility and jurisdiction.
Build.inc notes that interconnection queue studies in constrained markets frequently come with significant upgrade obligations attached. That is where this cost appears.
Why it is your problem anyway
The developer has one total budget for the site: land, enabling infrastructure, and the cost of time. If columns two and three are large, column one shrinks.
From DataCenterScope's illustrative comparison of two 100-acre sites:
| Site A | Site B | |
|---|---|---|
| Land | $120M | $40M |
| Enabling infrastructure | $30M | $100M |
| Timing cost | — | $36M |
| Total | $150M | $176M |
Site B's owner got a third of Site A's price per acre. The $70 million infrastructure gap is most of the reason.
What raises your price
Anything that shrinks the buyer's infrastructure bill:
- An existing substation nearby with real headroom
- Adequate transmission voltage close by
- Fiber already at or near the property line
- Existing industrial zoning
- A utility with large-load experience and a short queue
- Water and sewer already available where needed
None of these are cosmetic. Each one is money the buyer does not have to spend, and a portion of it is available to you.
