Settlement price economics

Observed ERCOT settlement prices at WHCCS_CC1 over 365 days (2025-10-12 to 2026-10-11). This plant is also crosswalked to WHCCS_CT1_ST, WHCCS_CT2; the point with the deepest price history is shown.

Average price: $31.02/MWh
Hourly range: -$151 to $1,259
Negative price hours: 355
TB2 spread benchmark: $49.7/kW-yr

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.
