Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at FTR_CC1 over 365 days (2025-09-18 to 2026-09-17).
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.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
Tenaska Frontier Partners and Power Team announced that construction would begin immediately on the 830 MW natural-gas-fired combined-cycle facility near Shiro, Texas. GBV-Texas L. P. was selected as EPC contractor, and General Electric was to supply three gas turbines and one steam turbine.
Tenaska Frontier Generation Station entered commercial operation.
The Frontier generating station entered commercial operation in September 2000.
Tenaska reported that the facility had completed 25 years of operation, generated nearly 100 million MWh, and continued supplying both ERCOT and MISO.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
