Project milestones and public references behind the asset profile.
EIA-923 reports gross generation and net grid exchange for storage plants. Gross generation is shown as a discharge proxy; it is not a cycle count or conventional capacity factor.
3 ERCOT market resources · Battery / storage
Cycles/day is discharged energy vs. usable capacity (~640 MWh). Capacity factor is avg discharge vs. peak.
Observed ERCOT settlement prices at JAG_SLR_RN over 365 days (2025-10-12 to 2026-10-11). This plant is also crosswalked to BKBN_RN; 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. 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.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
