Carson County, Texas: solar, storage and data center siting

Candidate land

Land holdings of 50 acres or more that Voltane screens for solar, storage and hybrid projects. Counts only; the sites and their scores are in the map.

Source: TxGIO StratMap Land Parcels 2025 (county appraisal dates Feb to Jul 2025), Voltane processing of 2026-09-29.

These are candidates before Voltane's screening filters (flood, wetlands, protected land, distance to 138 kV) and before any project type is chosen. The map shows how many pass for solar, storage or hybrid.

Transmission and substations

Source: lines: HIFLD Electric Power Transmission Lines (final release, 2024-09-30) merged with OpenStreetMap (Texas extract, 2026-09-29); substations: OpenStreetMap Texas extract, 2026-09-29.

23 mapped substations in all. A nearby line or substation is a proxy for grid access, not a statement that it can take a new project.

ERCOT interconnection queue

Unknown. Carson County lies outside ERCOT, so ERCOT's queue report does not cover it.

What this page does not tell you

• How much power any line or substation can take. That takes ERCOT or utility studies.
• Flood, wetland and protected-land shares for the county. Voltane measures those per site, in the map.
• Who owns land here. Voltane publishes no landowner names.
• Local ordinances, title, or field conditions.
