Settlement price economics

Observed ERCOT settlement prices at OLIN_OLING_1 over 365 days (2025-10-26 to 2026-10-25). This plant is also crosswalked to OLIN_OLING_2, OLIN_OLING_3, OLIN_OLING_4; the point with the deepest price history is shown.

Average price: $34.85/MWh
Hourly range: -$34 to $1,560
Negative price hours: 247
TB2 spread benchmark: $55.3/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.
