Observed ERCOT settlement prices at JACKCNTY_CC1 over 363 days (2025-09-11 to 2026-09-10). This plant is also crosswalked to JCKCNTY2_CC1; 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.
