One or Two PFs

[R2S]

Assume a net-metered facility that during a month, there are times when the facility is producing energy into the grid and times when the facility is consuming energy from the grid. This assumes the facility is large enough that the power factor (PF) is included in their billing calculation.

For such a case, do utilities calculate two PF's for a month (one for generation, one for consumption) or just one? If a single PF is calculated, how is it calculated?

You have to ask the utility. They ALL have their own schemes. There is no standard.

The old school method would be to measure the incoming KVARHrs and KWHrs and the outgoing KVARHrs and KWHrs all on a monthly basis. PF would be calculated from those figures.
There would be two sets of ratchet equipped meters, one for incoming and one for outgoing.

Yes, go ask the utility. The metering system and penalties seem to be different for every one.
