Barrio Grid Connector
Texas power grid siting data for AI agents and developers. Ask where the nearest substation is, what utility serves a site, whether it is inside city limits, which gas pipelines run nearby, what is in the ERCOT queue, what power sells for at the node, or which parcels sit next to high-voltage power.

5,394 substations · 7,033 transmission lines · 1,874 ERCOT queue projects · 664 planned upgrades · 2,317 pricing nodes · 908 battery projects · 497,000 pipeline segments · 415 compressor stations and gas plants · parcels statewide

One MCP server and a matching REST API. Works with Claude, ChatGPT, Muse and any agent that can call a URL.
No assistant to connect? The map has one on it. Dub Kittrell is an AI landman who runs the same tools and moves the map to the answer: ask him who serves a spot, what is queued nearby, or where the best battery spreads are. 20 questions a day on a free account. On Pro he runs as Dub+, on a stronger model. On Enterprise Lite he searches tracts near the right wire and names who owns them; on Enterprise he works as the Land Desk, with full site screens. How Dub works.

Tools
| Tool | What it answers |
|---|---|
| grid_context | Everything around one site: county, likely serving utility, 3 nearest substations, transmission lines, ERCOT queue projects and planned transmission upgrades within 25 miles, and railroads: the nearest rail lines and whether one lies between the site and its substation. Each substation carries an osm block: high and low side voltage (voltages_kv, high_side_kv, low_side_kv), OpenStreetMap class (transmission, distribution, switching, or not_mapped), source OpenStreetMap (ODbL); mapped transformer count on Pro. |
| nearest_substation | Closest substations to an address or coordinate, with voltage, owner and distance in miles. Filter by minimum kV. Also returns planned, unbuilt substations nearby (built:false, status, docket, expected date, pin confidence and the docket's location caveat) and warns when a planned and a built station share a name. Filters: osm_class (distribution, transmission, switching) and, on Pro, bus_kv_max (a station with any bus at or below that kV passes, which min_kv cannot express). Each substation carries an osm block from OpenStreetMap (ODbL): osm_class (transmission, distribution, switching, or not_mapped with a reason), distribution_bus_mapped (free), osm_name and match distance. Pro adds voltages_kv, high_side_kv, low_side_kv (when more than one voltage is mapped), transformer_count and transformer voltages, and osm_only_substations: up to 5 stations within 5 miles that are mapped in OpenStreetMap but not in the federal substation layer. |
| find_powered_land | Parcels near a qualifying substation, by county or point and radius, with acreage, owner and owner type (company, individual, trust or estate, public), situs address, legal description, appraised values, distance to the substation and wetland_pct (mapped wetland and open water share; max_wetland_pct filters wetter parcels; bus_kv_max and osm_class keep parcels whose nearest substation has a lower-voltage or distribution bus mapped in OpenStreetMap; Enterprise adds max_gas_mi, min_gas_diameter_in and gas_interstate to keep parcels near a mapped gas line, with nearest_gas_mi on each parcel; same_side_of_rail=true drops parcels with a railroad between them and their substation). Set group_by_owner to rank landowners by total acres near the substation. Enterprise Lite and Enterprise; Free and Pro get parcel and owner counts. |
| parcel_owner | Who owns land at an address, around a named substation or by property ID: property ID, acres, situs address, legal description and appraisal values. Owner name and mailing address on Enterprise Lite and Enterprise. Each parcel carries owner_class (university_lands, state, federal, county, city, school_district, special_district, railroad, utility, company, individual, trust_estate), undivided_interest when several owners share one property ID, city_limits_per_cad from the ICL/OCL legal token, and value_status (not_published_by_county means zeros are missing data, not a $0 parcel). utility_pad says whether a utility-owned parcel under 10 acres (a likely substation pad) sits within the radius: yes or no and a count for everyone, owner and property ID on Enterprise Lite and Enterprise; site_screen adds it as a flag within 1 mile. |
| jurisdiction | Who governs a site: county, inside city limits (which city), estimated ETJ, nearest city, school district, groundwater district or rule of capture, load zone, likely utility, FEMA flood zone, mapped wetlands on the spot and within half a mile (USFWS National Wetlands Inventory; type and acres on Pro), USFWS critical habitat within 5 miles, and whether the site is in a Qualified Opportunity Zone now and from 2027. cad_city_limits compares the appraisal roll's ICL/OCL legal token for the parcel at the point with the boundary layer and warns when they disagree. |
| pipelines_near | Gas pipelines near a site from Railroad Commission permits: operator, system, nominal diameter, interstate or intrastate, distance, miles of line in the radius. Nearest 12-inch-plus and nearest interstate line, a note on how interstate (FERC) and intrastate (Railroad Commission) taps and rates differ (Pro can filter to one), plus trunklines, compressor stations, processing plant capacity and EIA pipeline capacity projects within 15 miles. |
| fiber_near | Fiber near a site: routes by provider with distance (provider GIS paths and carrier long-haul corridors), the nearest carrier hotels, colo and data centers, and fiber-to-premises providers from the FCC. Pro adds fiber counts, aerial or underground placement, route and facility names and speeds. |
| water_screen | Groundwater near a site: aquifers under the point, the groundwater district, supply wells by depth, reported yields weighted by test method, the highest-yield wells, water quality and level trends, how many wells a stated demand needs, and the groundwater district's rules with citations (TWDB well records, monthly; district rules quarterly). |
| water_well_plan | Proposed water well and graded water buy areas: formation ranking, proposed depth and screen, expected yield, water quality, annual yield under the district cap, wells and acres of rights for a demand, and the analog wells behind it. Enterprise. |
| water_report | PDF water site report: geology and formation ranking, nearest graded water areas, the proposed well beside its analog wells, a geologic cross section through the site, water quality and the district rules with page numbers. Enterprise. |
| water_cross_section | Geologic cross section along a line from the state groundwater availability models: every aquifer and confining unit with depths, fresh and brackish zones where modeled, and the state wells near the line with their screens. Enterprise. |
| industrial_neighbors | Heavy industry already operating nearby (TCEQ emissions inventory) and recent TCEQ air permit applications, including data centers and gas plants before they reach the ERCOT queue. |
| site_screen | Enterprise. One-call screen for a data center, battery, generator, solar farm or industrial load: grid, prices, queue crowding, gas, jurisdiction, neighbors and the parcel at the point with its owner and that owner's nearby holdings, with a flags list (including railroads between the site and its substation) and a 0-100 score using stated weights. Free, Pro and Enterprise Lite get the score, flag counts, county, load zone and nearest substation. |
| report_pdf | Pro. Makes a one-page, print-ready PDF site screen for an address or coordinate: screen score, a to-scale schematic map of the nearest substations, substations and transmission lines within 5 miles with kV and owner, likely utility and load zone, and a screening disclaimer. Returns a link that expires after 30 minutes (a snapshot taken when you call it). Score, flag counts and grid facts. Enterprise also adds the strengths and risks, prices, gas, flood, jurisdiction and the parcel at the point. Free: a description of the report. |
| search_grid | Find a substation, company, planned project, battery (by developer, POI or INR), air permit, queue project, pricing node, city or county by name, with coordinates. |
| substation_detail | Everything about one substation: voltage, owner, lines, batteries interconnecting there, generation_queue_at_poi (total projects, mw_total, projects by fuel/mw/study_phase), queue, prices, an inferred station class (distribution, transmission, switching, generation tie, customer-owned) with its evidence, and how likely_utility was derived with a flag when it disagrees with the station owner. Planned upgrades on Pro; surrounding landowners on Enterprise Lite and Enterprise. Adds the OpenStreetMap osm block (class and whether a distribution bus is mapped; high and low side voltage and transformers on Pro) and uses the OpenStreetMap substation tag as strong evidence for station_class (basis says whether OSM agreed with or overrode the inference). Names are also matched against OpenStreetMap names (Normanna finds the station HIFLD calls Beek); a station mapped only in OpenStreetMap comes back as osm_only_substation. Pro lists osm_only_substations within 5 miles. |
| grid_projects | Pro. Planned new substations, approved lines and upgrades near a site, in a county or by utility, with status, expected date, cost, docket and sources. |
