Cycles/day is discharged energy vs. usable capacity (~129 MWh). Capacity factor is avg discharge vs. peak.
Observed ERCOT settlement prices at STAM_SLR_ALL over 365 days (2025-10-12 to 2026-10-11).
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.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
Answered from the published record above. Questions whose inputs this profile does not carry are omitted rather than estimated.
Stampede Solar reports 72.2 MW battery storage + 255.9 MW solar of operating nameplate capacity. These technology ratings do not establish a common export limit. Source: EIA Aug 2026.
