Watt Loss/kVAR of Reactive Power Compensating Device

Please note that PF improvement only compensates for the lagging REACTIVE power and it does very minimal to improve on active power consumption.

The question starts with a quotation mark. This makes it look as though the OP is passing along a question posed by someone else. If so, the OP should request this someone else not to ask nonsense questions.

The primary reason for installing capacitors to an electrical system is to reduce demand. When a customer is being billed a penalty for kva demand, you can save money by reducing this KVA demand. Installing capacitors and improving power factor will do this. As a side benefit, depending on where the capacitors are installed, you will save I²R losses and reduce kwh's. However, the primary reason for improvng PF is to reduce demand.
