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.
