Settlement price economics

Observed ERCOT settlement prices at LONESTAR_RN over 364 days (2025-09-07 to 2026-09-06).

Average price: $37.12/MWh
Hourly range: -$30 to $1,157
Negative price hours: 881
TB2 spread benchmark: $61.4/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. 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.
