The Texas power grid, mapped for siting
Every substation, transmission line, ERCOT price node, queue entry and data center project on one map. Built for people who site power.
Last 90 days in Texas: 17 data centers announced, 3 battery projects entered the queue, 23 air permits filed.

The 345 kV backbone
The extra-high-voltage spine that moves West Texas wind and Gulf Coast gas to the load. Every mapped line carries its voltage, owner and status, with planned lines and CCN dockets alongside.
Where you plug in
Every HIFLD substation, sized by voltage class, tied to its ERCOT settlement point and the TDU that owns the wires. The pads on the model are the stations at 230 kV and up.

Read the queue before you sign the lease
ERCOT generation and battery queue entries at every station, with names, MW, status and dates on Pro. See who is already in line at the substation you are looking at.

The load is coming
Each white hall on the model is a data center campus, sized by announced megawatts. Developer, end user, utility, substation, abatement and local opposition, sourced and dated.
290 campuses
Power has a price at every node
Day-ahead and real-time hourly prices at every settlement point, with TB4 spreads, negative hours and spike counts rolled up per node per day. Ancillary clearing prices back to January 2024.

Down to the dirt
Appraisal parcels for 253 of 254 counties. Enterprise Lite adds tract search near substations by acreage, distance and kV, with landowner names, mailing addresses and appraisal values, and prices land around a tract: appraised $/acre, nearby asking prices and an offer range.

Developers
Screen a county in an afternoon: stations, queue, price, local mood, land.
Brokers
Know what a tract is worth to a power buyer before the listing call.
Storage and solar
Node spreads, negative hours, curtailment and queue depth at the station.
Funds and lenders
Check a sponsor's site story against the grid, the queue and the county.
Water under the site
Does your project need its own water supply? Aquifer outlines, 857,000 cleaned Texas water wells from the state well databases, every well tied to its formation, and the rules of each groundwater district with page numbers. Ask Dub where the nearest good water is and what the geology looks like, then plan a well for your demand.
Free
Aquifers at a point, the groundwater district, wells by depth band and counts near a site.
Pro
Well cards with yield, water levels over time and chemistry; yields and salinity by aquifer; the district's pumping rules with page numbers; wells needed for your demand.
Enterprise
Water buy areas graded A, B and C along the aquifer belts; a proposed well drawn beside the real wells it rests on; geologic cross sections from the state groundwater models; and a PDF water report for the site.

Texas grid map FAQ
Is there a map of the Texas power grid?
Yes. Barrio Grid maps every substation, transmission line, ERCOT settlement point, queue entry and data center project in Texas. It is free to start, with email sign-in and no card.
How do I find substations near me?
Open the map and click anywhere. You get the nearest substations with voltage, owner and distance, and the ERCOT price node each one settles at.
What is an ERCOT settlement point?
A location where ERCOT prices energy. The map shows day-ahead and real-time hourly prices for all 2,324 of them, with TB4 spreads, spike counts and negative-price hours.
Where is the data from?
HIFLD and OpenStreetMap for substations and lines, ERCOT for prices and the queue, the PUCT for dockets, the Railroad Commission for pipelines, TCEQ for air permits and county appraisal districts for parcels. Prices refresh daily.
How do I find land near a substation?
Enterprise Lite adds tract search near substations by acreage, distance and kV, up to 200 tracts per search, with landowner names and appraisal values.
Can I use it from ChatGPT or Claude?
Yes. Add https://grid.barrioenergy.com/mcp as a connector. The same tiers and limits apply.
