Yes, they can
measure power factor, but my poco doesn't
bill residential customers for having a low power factor. it's been a long time since I've seen a mechanical meter around these parts.
for commercial customers:
Quote:
Billed On-Peak Demands
The demand charges herein are based on a standard power factor of 85 percent. Billed on-peak demand shall be determined by the following formula less any amount calculated in No. (3) below related to new equipment testing demand:
(a) For power factors at 85%
Billed on-peak demand = measured on-peak demand
(b) For power factors below 85%
Billed on-peak demand =
(measured on-peak demand) [1 + (0.65)(0.85 – peak power factor)]
