Never add these figures to each other, to a utility forecast that already includes the facility, or across facilities. The utility on a dossier is the one a filing or contract names. Proximity to a substation, a service-territory polygon or a balancing authority never establishes who serves a facility.

• A superseded announcement restates the earlier one: the chain is one figure, not several.
• A service request, a minimum billing demand, a contracted capacity and a metered use describe one facility in different roles; the same MW can appear in more than one.
• A utility's class forecast (Idaho Power's additional firm load, PGE's data-center load) already contains its named customers: adding a named figure counts it twice.
• MW, MWa, MWh and square feet are different quantities; dollars are not load.
