## Data quality

- These may represent different completion and commercial-operation conventions. Early environmental and interconnection materials described a solar-plus-storage configuration, while the EIA operational plant record lists only the 200 MW solar generator. The CAISO queue record should therefore be treated as historical or interconnection information rather than evidence of an additional operating EIA generator. The more than $700 million construction-financing figure covered Luna Valley and the separate Daggett Storage project together.
