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.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
The California Public Utilities Commission approved PG&E’s contract with Kola Energy Storage for 275 MW of lithium-ion battery storage.
CPUC approved an amendment extending the initial delivery date from June 1, 2024, to June 1, 2025, and allowing a price increase. The delay was attributed in part to transmission-owner delays affecting interconnection upgrades.
EIA-860 lists generator KOLA, generator KOLA2 with this operating date.
