Why do electrical utility operators such as SBEE penalize industrial installations operating with a low power factor (e.g., cos phi < 0.90)?

Low power factor increases line current for the same active power, causing higher I^2*R transmission losses and voltage drops Low power factor reverses active energy meters and creates negative power generation Low power factor increases the AC supply frequency above standard 50 Hz limits Low power factor causes direct short circuits in distribution step-down transformers

Correct Answer:

Low power factor increases line current for the same active power, causing higher I^2*R transmission losses and voltage drops
