CONSTELLATION POWER SOURCE GENERATION, LLC
Active
The chain ends here. No other entity reports CONSTELLATION POWER SOURCE GENERATION, LLC as its parent, so the count is a stated zero rather than data still to arrive.
Level 2 data records who consolidates this entity. A reported relationship, or a reported reason for the absence of one, both satisfy the standard. Only a record carrying neither is incomplete.
