Aypa Power’s corporate site and press release state that Aypa Power 'develops, owns, and operates' utility-scale storage projects and that the November 8, 2023 portfolio financing 'supports... the Borden County project (a 150MW / 300MWh battery storage project in Texas)'. These statements identify Aypa Power as the project's developer/portfolio owner, while separate registry filings show the legal operator entity as the project-specific LLC.
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.

Cycles/day is discharged energy vs. usable capacity (~370 MWh). Capacity factor is avg discharge vs. peak.
Observed ERCOT settlement prices at BOCO_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.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
