Wyoming market leads North America's data center development rankings as WECC grid shows strongest buildable capacity signals
## Cheyenne Leads BUILD Rankings
Cheyenne, Wyoming claimed the top position in DC Hub's Data Center Power Index (DCPI) BUILD ranking today with an excess power score of 69.5, signaling the strongest grid conditions for new data center development across all tracked North American markets.
The WECC-connected market outpaced Montréal, QC (65.2, HQ grid) and La Vista, NE (59.8, SPP grid) in today's rankings. Cheyenne's low constraint score of 22.5 indicates minimal grid bottlenecks, a critical factor as hyperscalers and colocation operators search for sites capable of supporting multi-hundred-megawatt AI infrastructure builds.
## What It Means
The DCPI excess power metric quantifies available grid headroom by combining substation capacity, transmission corridor strength, utility interconnection queue data, and real-time ISO telemetry. Markets scoring above 60 typically support immediate development without major utility upgrades.
Meanwhile, constraint-heavy markets remain under pressure: Dublin, OH (PJM, 22.4 excess / 72.5 constraint), London, UK (NGESO, 13.5 / 71.8), and Amsterdam, NL (ENTSOE-NL, 13.7 / 70.0) continue to face grid saturation challenges that delay or block new capacity.
## Methodology
DC Hub's DCPI scores are updated daily using live telemetry from 43 US balancing authorities, plus UK, EU, Taiwan, and Australia grid operators. The platform tracks 21,000+ data center facilities across 234 markets and 170+ countries.
