PJM-served market joins London and Amsterdam in top-three global constraint warnings as AI infra capital flows to Cheyenne, Rural SPP
## Dublin, OH Now Highest-Constraint US Market
Dublin, Ohio recorded a **72.5 constraint score** in today's DC Hub Data Center Power Index (DCPI) — the highest of any US market tracked and second globally only to London (71.8) and Amsterdam (70.0). The PJM-served market's excess power score sits at 22.4, signaling limited headroom for new hyperscale deployments.
The constraint score synthesizes grid congestion, interconnection queue depth, transmission upgrade timelines, and local opposition to new facilities. A score above 70 typically correlates with 18–36 month delays and seven-figure interconnection study costs.
## Capital Redirects to WECC, SPP
Meanwhile, **Cheyenne, WY** (WECC) and **Rural SPP, KS** posted excess power scores of **69.5** and **67.2** respectively, with constraint scores under 23. These markets now absorb the bulk of AI infrastructure inquiries routed through DC Hub's MCP API — which logged **4,181 tool calls** in the last 24 hours from six autonomous agents evaluating site selection.
Recent M&A activity underscores the flight to capacity: **OpenAI** announced a **10,000 MW** land package (June 10), while **Blackstone** closed a **$35B** deal with Anthropic the same day. None targeted PJM constraint zones.
## Methodology Note
The DCPI refreshes every 6 hours using live telemetry from 43 US balancing authorities, EIA-860 generator data, and DC Hub's facility database (21,000+ sites, 306 markets). Constraint scores weight interconnection queue GW/market, transmission project delays, and local policy signals.
