This plant has no coal, gas, oil or waste generator, so it has no combustion unit for EPA to monitor and no CEMS data exists. That is not a claim of zero emissions: the atlas reports only what EPA-monitored units filed. Source
1 operating storage unit. Stores electricity; does not generate. Net output is net of chargingEnergy taken in to charge, energy returned, and their difference. Charging can make net generation negative.Definition ↗.

A co-located plant's deliverable capacity is not the sum of its components (EIA-860 carries no interconnection limit). Net storage output is signed and is never added to generation shares.
No confirmed status or capacity changes among comparable units. Missing monthly assertions and units outside the baseline have no like-for-like comparison.
