Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at REROCK_ALL over 363 days (2025-09-11 to 2026-09-10).
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.
View full reporting portfolioRecurrent Energy closed a combined construction and term debt facility in December 2015 with KeyBank as coordinating lead arranger and a five-bank syndicate (including Rabobank, Santander, NORD/LB and CIT) providing project construction debt, LC facilities and a back‑leveraged term facility totaling approximately $275 million.
The project entered commercial operation in the fourth quarter of 2016 and began delivering energy under a 20‑year PPA with Austin Energy.
