ATC & Offtake Data

Access Best in Class Grid Injection & Offtake Capacity

  • Available power at each point of interconnection, substation or line tap

  • Instant visibility into the maximum additional load the grid can absorb before a network upgrade is needed

  • Network Resource vs. Energy Resource analysis, modeled across Base Case, Post Contingent, Existing System, and Queued scenarios

  • Estimated network upgrade costs and limiting elements (lines, transformers) for each point of interconnection

Transmission Siting Data

Pair Land Data With Grid Data to Find the Right Corridor

LandGate doesn't route transmission lines. It gives the land and power data that makes routing decisions faster and more defensible: parcel ownership, buildable acreage, exclusion zones, and interconnection capacity, all in one view.

  • Proximity of available and buildable parcels to existing and planned transmission corridors

  • Transmission and distribution line mapping, down to voltage and ownership

  • Buildable acreage and exclusion zone analysis along a corridor: topography, wetlands, protected lands

  • Lease and easement activity mapped at the parcel level in the Utility category, so you can see what corridor adjacent land is already spoken for

Power Pricing Data

Underwrite the Interconnection Point, Not Just the Land

A corridor or point of interconnection isn't just a physical question, it's an economic one. LandGate's pricing data closes that loop.

  • Nationwide coverage: over 56,000 pricing nodes across all seven U.S. ISOs (CAISO, ERCOT, ISO-NE, MISO, NYISO, PJM, SPP); ERCOT alone carries more than 20,000 of those nodes.

  • Node vs. hub basis risk analysis, with 25th and 75th percentile daily price comparisons

  • Weather risk modeling to anticipate market impacts on pricing
    25 years of historical hourly and daily LMP data, exportable for analysis
