What a joke.

The "power coming into the building" can be no more than the power being
used by the building's equipment, devices or appliances.

That fact that I've got some high-rated switch gear and primary supply
wire shouldn't play a role in how I'm billed. It's still a basic
3-phase 120/208 supply. Nothing fancy.
