Wyoming market shows operational tension: strong grid headroom masks rising interconnection friction as AI-capacity demand accelerates.
## Highlights
Cheyenne, Wyoming's DCPI constraint index has risen to **22.5 out of 100** while excess-power capacity remains at **69.5** — a widening divergence that signals growing interconnection queue pressure despite ample available grid supply. The market continues to rank among the top three US build destinations, but the climb in constraint score reflects real time-to-power friction.
## What It Means
For hyperscalers and site-selection teams, Cheyenne's split signal is critical: you have the power, but the path to grid connection is getting tighter. Constraint acceleration in a top-build market typically precedes either queue compression (through tower-up or generator acceleration) or a shift in competitive positioning for shovel-ready projects. Teams already committed to WECC should expect interconnection timelines to remain the gating factor, not megawatt availability.
The 47-point gap between excess-power and constraint indices also suggests that while WECC supply economics remain favorable, the operational bottleneck has moved upstream: land and interconnection now dominate capex risk, not fuel or wholesale price.
## Second-Order Read
Rural SPP's constraint index holds at 22.5 (matching Cheyenne), but its excess-power score of 67.2 is 2.3 points lower. This means Cheyenne offers better overall build economics *if* interconnection timeline can be resolved. Developers still evaluating between WECC and SPP should weight the constraint parity but favor Cheyenne for power headroom — provided their supply chain can absorb a longer queue wait.
## Methodology
The DCPI excess-power and constraint indices measure available grid headroom (0–100, higher = more available) and interconnection friction (0–100, lower = faster path to grid) across 280+ US markets. Both are updated daily and weighted by queue depth, generator availability, and transmission congestion.
