Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at TNP_TNP_O_1 over 363 days (2025-09-11 to 2026-09-10). This plant is also crosswalked to TNP_TNP_O_2; 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.
EIA reports October 1991 for Unit 2.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
