The Texas Comptroller summary and the project press release identify the Revolution project as developed/owned/operated by Spearmint Energy and the company press release announces the project's completion under the Spearmint name.
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.
Observed ERCOT settlement prices at SPTX12B_RN over 363 days (2025-09-11 to 2026-09-10). This plant is also crosswalked to TBWF_ES_BES1; 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.
