Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at DDPEC_CC1 over 365 days (2025-10-27 to 2026-10-26). This plant is also crosswalked to DDPEC_GT1, DDPEC_GT2, DDPEC_GT3, DDPEC_GT4, DDPEC_GT6, DDPEC_ST1; 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.
EIA lists June 2004 operating dates for CTG3, CTG4, and STG1.
EIA lists June 2014 as the operating date for the sixth generator.
Shell described the Deer Park FEED study and a design target of roughly 5 million tonnes of net CO2 capture per year.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
