Those are not watts, those are VARs, magnetizing currents for induction motors and other inductive devices. They don't appear on the end user's meter because they're not watts at all.
And it is what PAS is, a variable capacitor bank. Capacitors supply VARs in an AC system. Utilities install passive capacitor banks in switchyards and substations where they need to for voltage support. Where there's a large customer as a primary cause of it, they'll make them pay for it. They've been doing it forever.
I swear I’ll never use the phrase “you can’t make this stuff up” ever again after being on the OTC. Apparently you can.
