| Validation-selected Build Chance | 74% |
| P05 | 68% |
| P50 | 77% |
| P95 | 87% |

### Score factors

| Factor | Percentage-point contribution |
| --- | ---: |
| Stage base rate | +91.5 pp |
| Fuel adjustment | -0.7 pp |
| Developer-history adjustment | -10.0 pp |
| Stage-velocity adjustment | +2.1 pp |
| COD-slippage adjustment | -10.0 pp |
| FIS-progress adjustment | 0.0 pp |
| Capacity adjustment | +0.9 pp |

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

## Observed monthly history

- First seen: 2021-12
- Last seen: 2026-08
- Appearances: 56
- 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.

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.
