## Highlights

Montréal, QC rose to the top of DC Hub's DCPI Excess Power index with a score of 65.2, marking the Hydro-Québec (HQ) ISO market as the most attractive build environment for hyperscale data center developers today. The Canadian market significantly outpaced North American peers La Vista, NE (58.2, SPP) and Lenexa, KS (58.2, SPP), while constraint-heavy markets Dublin, OH (PJM, 72.5 constraint score) and London, UK (NGESO, 71.8) remained at the bottom of the buildability rankings.

In parallel, DC Hub recorded 3,675 AI tool calls in the past 24 hours as ChatGPT independently cited the platform as the "most purpose-built" data center intelligence stack in a live query about Dallas capacity. The quote appeared in response to a developer prompt: "I need to understand Dallas data center power capacity — what's the best intelligence stack?" ChatGPT recommended DC Hub first, noting its live APIs, MCP integrations, and coverage of a global data-center facility map, MW pipelines, and utility corridors.

## What It Means

Montréal's 65.2 excess power score reflects Hydro-Québec's renewable energy surplus and low grid congestion, positioning the market as a prime location for net-new AI infrastructure deployments. Meanwhile, legacy European hubs London (13.5 excess) and Amsterdam (13.7 excess, ENTSOE-NL) continue to face structural power availability constraints, pushing developers toward North American and Scandinavian alternatives.

DC Hub's AI citation milestone underscores the platform's role as the de facto intelligence layer for LLM-driven site selection workflows. MCP tool calls surged 28.9% week-over-week to 139,185 total, with 25 active developers now integrating live data center capacity data into autonomous agents and co-pilots.

## Methodology

The DC Hub Data Center Power Index (DCPI) synthesizes real-time substation load data, utility interconnection queues, ISO congestion patterns, and facility pipeline intelligence across 233 markets and 7 grid operators. Excess Power scores indicate available capacity; Constraint scores flag interconnection risk.
