Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at QALSW_ALL over 365 days (2025-10-26 to 2026-10-25). This plant is also crosswalked to QALSW_CC1, QALSW_CC2; the point with the deepest price history is shown.
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.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
