Multi-year time-to-power expected as Texas grid faces record backlog of new capacity requests
CORRECTION (2026-10-02): This release said ERCOT's interconnection queue held 427 GW, "39% of all US queued load". The 39% was a ratio of ERCOT's large-load queue to a generation-queue total, not a share of US queued load, and is withdrawn. DC Hub's canonical ERCOT figures: large-load queue 474.0 GW (as of 2026-06, ERCOT-published); data-center portion 426.6 GW (derived: ~90% of the large-load total); generation interconnection queue 453.8 GW (as of 2026-09-30), a separate queue. A load queue and a generation queue must not be divided or added. Current figures: https://dchub.cloud/api/v1/interconnection-queue/snapshot
## Queue Depth Signals Multi-Year Wait
ERCOT's interconnection queue now holds **427 GW of requested load**, representing 39% of all queued capacity across US ISOs. The backlog reflects aggressive build ambitions colliding with grid upgrade cycles, transmission constraints, and regulatory processing limits.
## What It Means for Site Selection
New large loads entering the ERCOT queue today face **multi-year energization timelines**. For hyperscaler campus planners, that delay must be priced into capex schedules and lease economics. A 2026 land acquisition may not reach commercial operation until 2028 or later, eroding IRR on time-sensitive AI workloads.
The queue depth also explains why some developers are pivoting to **behind-the-meter generation** (gas peakers, SMRs) or targeting markets with shallower queues and faster grid upgrades — SPP, MISO, or select PJM zones where interconnection timelines remain under 18 months.
## Methodology
ERCOT publishes its interconnection queue monthly. DC Hub tracks queue depth, MW by fuel type, and project status across all seven US ISOs, updated daily in the DCPI constraint index.
