WECC market leads nationwide on available grid capacity, but time-to-interconnection remains the critical diligence item
## Highlights
Cheyenne, Wyoming now holds a **70/100** score on the DC Hub Data Center Power Index (DCPI) excess-power metric—the highest of any tracked US market and 48 points above Dublin, OH (22/100). The city's constraint score sits at just **22.5/100**, signaling minimal transmission or substation bottlenecks compared to saturated metros like Dublin (72.5) or London (71.8).
## What It Means
Cheyenne sits at the top of the build shortlist on available power. The combination of low constraint risk and deep headroom makes it attractive for hyperscale deployments that can absorb 50+ MW per phase. But **verify time-to-power before committing capital**: WECC interconnection queues are climbing, and local utility readiness varies. A 70 DCPI score says power exists; it does not guarantee a six-month energization timeline.
## The Second-Order Read
Rural SPP markets (Kansas) score **67.2/100** on excess power—nearly as high as Cheyenne—yet draw a fraction of the attention. If Cheyenne land or utility timelines slip, SPP's underpriced, under-allocated grid becomes the swing alternative for developers willing to trade brand zip code for speed and cost.
