Bill can be reduced only if surcharge for low power factor/reactive power charges are in the tariff. As of now domestic and most of the low demand LT loads do not attract such charges.

What about varying loads? How variable reactive power is produced at consumer end and at what cost and efficiency? Is it necessary that every piece of equipment work at unity power factor or is it economical to take care at the aggregate level?

energy is equal to kw multiply by hour… these we bill by electric cooperative
im confuse pls explain.. ty

Dear Farhan we can reduce bills by power factor correction but for commercial loads the power factor is of not so importance.
