Settlement price economics

Observed ERCOT settlement prices at FTWIND_UNIT1 over 365 days (2025-10-27 to 2026-10-26). This plant is also crosswalked to CTL_PUN1; the point with the deepest price history is shown.

Average price: $28.07/MWh
Hourly range: -$116 to $1,161
Negative price hours: 1,187
TB2 spread benchmark: $52.5/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.
