## The Queue Depth
ERCOT's interconnection queue holds **438 GW of requested load**—representing **39% of all US queued capacity** and a historic concentration of infrastructure demand on a single grid. This backlog is not a quarterly fluctuation; it reflects multi-year study timelines, transmission upgrade dependencies, and the grid's finite ability to service new large loads in parallel.
## What It Means for Site Selection
New large AI and hyperscale loads in ERCOT now face realistic **3–5 year delays** between commercial operation date (COD) and full interconnection. This is not a transmission constraint alone—it is a queue discipline problem. Sites chosen in ERCOT today must price in: phased power delivery (partial load energization), interim generation or battery backup, and extended capex schedules. Developers accustomed to 18–24 month time-to-power in constrained grids like PJM or ISO-NE should add 18–36 months to their ERCOT timeline.
The economic consequence is real: a 50 MW facility with $50M annual opex will incur an estimated $75–150M in carry costs (financing, temporary power, lost revenue) during the queue wait. Site selection now requires grid queue position as a line item in the build NPV model, not an afterthought.
## The Implication Beyond ERCOT
When a single grid holds 39% of national queued load, capital migration has already happened. The concentration signals that hyperscalers have exhausted faster-to-power alternatives (SPP's Kansas/Oklahoma markets, for example, show median excess power at 77/100 with shorter queue depths). Texas remains attractive on price and wind resource, but *when* a site energizes now matters more than *where* in the state. Developers should evaluate ERCOT alternatives—particularly SPP markets with lower queue density and higher available headroom—for projects with hard deadline constraints.
