Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at PRSPERO2_ALL over 365 days (2025-10-27 to 2026-10-26).
The TB2 figure is a price benchmark, not revenue: it values one perfect-foresight cycle per day between the 2 cheapest and 2 dearest hours of each day, gross of round-trip losses, and excludes ancillary services and any physical dispatch constraint. It describes what this node’s price shape was worth over the window — it is not this asset’s realized capture, and no dispatch is assumed or modelled.
Matched to the latest available ERCOT generation-interconnection queue record. Queue status and completion dates describe the queue record; operating status is verified separately against plant and market registrations.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
EIA reports August 2021.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
