Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at BTE_BTE_G1 over 365 days (2025-10-27 to 2026-10-26). This plant is also crosswalked to BTE_BTE_G2, BTE_BTE_G3, BTE_BTE_G4, BTE_CC1, BTE_PUN1, BTE_PUN2, EXN_PUN1, EXN_PUN2, EXN_PUN3; the point with the deepest price history is shown.
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.
Baytown Energy Center entered combined‑cycle operations; commissioning and commercial operation reported in June 2002.
Calpine’s Baytown Carbon Capture project was selected by the U.S. Department of Energy for a cost‑sharing agreement to advance commercial‑scale carbon capture and storage infrastructure.
Reporting indicates Phase 1 funding for the project (reported $270 million) in mid‑2024 as part of the DOE cost‑sharing implementation and project phasing.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
