ERCOT
ERCOT · Comal County
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.
1 ERCOT market resource · Battery / storage
Cycles/day is discharged energy vs. usable capacity (~484 MWh). Capacity factor is avg discharge vs. peak.
Observed ERCOT settlement prices at EBNY_ESS_RN over 365 days (2025-10-26 to 2026-10-25).
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.
Matched to the latest available ERCOT generation-interconnection queue record. Queue status and completion dates describe the queue record; operating status is verified separately against plant and market registrations.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
