Texas transmission lines, substations and planned upgrades on the Barrio Grid map
Texas power siting intelligence

Every substation in Texas. One map. One API.

Find power before you find land. Barrio Grid maps the whole Texas grid, from 765 kV backbone to the parcel next to the substation, and answers siting questions in milliseconds on the web, in code, or inside your AI assistant.

What is coming

Read the queue before you sign the lease

Solar, wind, storage and gas projects in the ERCOT interconnection queue, with MW and study status, sit next to the transmission that is being built. See where generation is crowding a node and where new 345 kV and 765 kV capacity is headed.

  • 1,874 queue projects by fuel and MW
  • 664 approved, proposed and under-construction grid projects
  • Substation owners enriched and checked against OpenStreetMap

AI native

Ask your assistant. It asks the grid.

Barrio Grid is a Model Context Protocol server. Add one URL to Claude, ChatGPT or Muse and your assistant can answer siting questions with live grid data instead of guesses. Developers get the same six tools as a REST API.
