County is the public geographic precision used by ERCOTQueue. Map symbols are county-level evidence and are not exact project coordinates.

## Independently derived Build Chance

| Measure | Value |
| --- | ---: |
| Validation-selected Build Chance | 81% |
| P05 | 75% |
| P50 | 80% |
| P95 | 86% |

### Score factors

| Factor | Percentage-point contribution |
| --- | ---: |
| Stage base rate | +80.8 pp |
| Fuel adjustment | -0.7 pp |
| Developer-history adjustment | 0.0 pp |
| Stage-velocity adjustment | +1.7 pp |
| COD-slippage adjustment | -2.0 pp |
| FIS-progress adjustment | 0.0 pp |
| Capacity adjustment | +1.5 pp |

These factors are ERCOTQueue derivations. The displayed probability is not an ERCOT forecast or an official project status.

## Reported milestones

| Milestone | Date |
| --- | --- |
| screening started | 2023-07-31 |
| screening complete | 2023-10-27 |

## Observed monthly history

- First seen: 2023-07
- Last seen: 2026-08
- Appearances: 38
- Score-series basis: Monthly points use the as-of seven-factor raw model on the validation-selected raw scale because the current isotonic candidate did not pass the project-purged application guard. The final point is anchored to the published current project score. The series shows trajectory, not a previously published frozen forecast.

The 30 most recent observed changes are shown below. The public JSON contains the complete history.

| Report month | Change | Detail |
| --- | --- | --- |

ERCOTQueue distinguishes reported source fields from independently derived analysis. Queue capacity records development and interconnection activity; it does not establish financing, construction, or commercial operation. Build Chance is a research signal, not a guarantee or investment recommendation.
