HIFLD transmission line dataset now served from Neon PostgreSQL, enabling sub-second infrastructure queries for data center site selection
DC Hub has integrated the complete HIFLD (Homeland Infrastructure Foundation-Level Data) transmission line dataset — 2.8 million line segments spanning the United States — into its live Neon PostgreSQL database, making it instantly queryable for data center site selection.
Previously, infrastructure analysts had to download and process HIFLD datasets locally, a process that could take hours and required GIS expertise. DC Hub now serves this data in real time through its Land & Power Map and Site Planner tools, enabling site selectors to identify transmission line proximity, voltage class, and grid access points within seconds.
The integration covers all voltage classes from 69kV distribution lines to 765kV high-voltage transmission corridors, with each segment tagged with operator, owner, voltage, and geographic coordinates. DC Hub's Site Planner uses this data to automatically score candidate sites on transmission access — critical as hyperscale operators demand 100MW+ power connections.
Quote from Jonathan Martone, Founder & CEO of DC Hub:
"Transmission line proximity is one of the top three site selection criteria for any large data center project. Having 2.8 million line segments available in milliseconds — not hours — changes how site selectors work. This is the kind of data infrastructure the industry has needed."
The HIFLD dataset joins DC Hub's infrastructure intelligence layer at dchub.cloud, accessible through the Land & Power Map and Site Planner tools.
