KISS,
Why is that? A higher line voltage will be required to do that, and the utility is not going to raise their voltage so they can pump more current into your service. Take the extreme case. Suppose you attach a humongous capacitor to your electrical service. For the most part, you will not be dissipating any energy that can be billed to you. And yet, the utility has to supply a lot of current back and forth and swallow the IR line losses. No matter what the voltage is, they will not be able to bill you for the energy transfer of the reactive load, which corresponds to a PF of 0. They don't like that, so they will bill you extra for having such a lousy PF. The bottom line is that they can deliver more billable power with the same current load when the PF is close to 1.

...The point I was trying to make is a source with a higher current capability is required.
