Settlement price economics

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

Average price: $31.73/MWh
Hourly range: -$34 to $1,358
Negative price hours: 226
TB2 spread benchmark: $45.8/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. 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.
