Answer / mahavir jagdev

They can be charged in Kvah only in case of DC transmision. In AC transmission due to the inductive or capacitive load the power factor comes into play, hence the effective metering is done on Kwh basis. Infact the energy company instruct the consumer whow has a lot of inductive load (motors) to put capacitor banks to keep the power factor within 0.85 region for lower powerline losses.

Answer / raj

Yeah... now industrial consumers are billed on KVAH only in Andhra Pradesh. Actually, this way of billing is the correct method to curtail low power factor problem in industries. In this case, we calculate the energy as below.
apparent energy,kvah = active power (kw)in each time block /power factor in each time block

Note : 1.presently the meters are designed for 15 minutes blocks.
2. In this billing method, the discoms dont penalize seperately for low power factor(as we already considered in thecalculation of apparent power.)
In the case of domestic, energy is billed for kwh only as it is uneconomical to place trivector meters ( as they consume less power and thier impact is very low on grid compared to industrial consumers )
