Observed ERCOT settlement prices at DOWGEN_PUN2 over 365 days (2025-10-27 to 2026-10-26). This plant is also crosswalked to DOWGEN_PUN3, DOWGEN_PUN4, DOWGEN_PUN5, DOWGEN_PUN6, DOW_61_2_63, DOW_64, DOW_81_2_84, DOW_G37_G35, DOW_G66_ST65, DOW_G67, DOW_G96_ST95; 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.
