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.

17 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
5 projects, 808 MW in ERCOT's generation interconnection queue list Coke County.
| Fuel | Projects | MW |
|---|---|---|
| Solar | 2 | 424 |
| Battery storage | 3 | 384 |
| Status | Projects | MW |
|---|---|---|
| Interconnection agreement signed | 1 | 151 |
| No interconnection agreement yet | 4 | 657 |
Queued MW show where other developers have asked to connect. They are a competition signal, not a measure of grid room, and many queued projects are never built.

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.
