Wyoming market shows strongest power headroom in tracked universe, but time-to-interconnection remains the final gating factor for hyperscale builds
## Cheyenne leads on available power
Cheyenne, WY scored **70/100** on the DC Hub Power Index excess-power metric as of June 27, the highest figure of any tracked US or global market. The market's constraint score sits at just 23/100, signaling low grid congestion and minimal interconnection queue friction in the WECC footprint.
## What it means for build decisions
Cheyenne now sits at the top of most hyperscale build shortlists when ranked purely on available power headroom. The market offers a rare combination: low existing load, access to wind and gas generation, and a regulatory environment that has historically approved large interconnections without multi-year delays.
But excess power is only half the equation. **Time-to-interconnection and utility willingness to fast-track service requests** vary widely even within low-constraint markets. A 70/100 excess score tells you the grid can absorb the load; it does not guarantee a 12-month timeline to energization. Before committing land or announcing a campus, verify substation capacity, transformer lead times, and whether the local utility has a track record of moving quickly on 100+ MW requests.
## Second-order implications
Cheyenne's leadership also highlights a structural shift: the markets with the best power stories today are increasingly *non-traditional* data center geographies. Dublin, OH (22/100 excess, 73/100 constraint) and London, UK (14/100 excess, 72/100 constraint) anchor the opposite end of the index â legacy colocation hubs now pinned by grid saturation and multi-year queue backlogs. Capital is following power, not legacy fiber or tenant ecosystems.
