Settlement price economics

Observed ERCOT settlement prices at BYU_BYU_1 over 365 days (2025-10-27 to 2026-10-26). This plant is also crosswalked to BYU_BYU_12, BYU_BYU_34, BYU_BYU_G8, BYU_CC1, BYU_G4_RN, BYU_PUN1, BYU_PUN2, BYU_PUN3, BYU_PUN4; the point with the deepest price history is shown.

Average price: $35.09/MWh
Hourly range: -$22 to $777
Negative price hours: 132
TB2 spread benchmark: $42.8/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.
