The major application of power factor correction is in reducing the maximum demand of apparent power (kVA) consumed by the customer as measured by the supply authority.
In reducing the maximum demand the customer is able to markedly reduce their electricity bill as a result of the way energy retailers charge their customers. There is also an environmental benefit as a result of more efficient electricity use. Larger customers are billed according to not only the real power they consume but also the level of apparent power the network needs to provide to them. This structure apart from normal kWh metering also includes a maximum demand charge, which is based on kVA demand metered on a half hourly basis, which reflects the customers’ power factor. The customer is charged for the kilowatt-hours used but a surcharge is then applied according to the maximum kVA drawn at any one point during the billing period. As such, cost savings may be realized by reducing the maximum kVA drawn through the installation of power factor correction
Power Factor Correction Benefits
Where to Install PFC There are several different ways in which PFC equipment can be installed. PFC can be applied to separate pieces of equipment that is switched in and out as the pieces of equipment are switched on and off. The alternative to this is to bulk correct an installation by attaching the equipment to the main switchboard. Solutions: Commercial – Industrial – Education

Typical Efficiencies of Electric Motors in the Building Industry
In Australia, more than 1.7 million three-phase electric motors run in industrial and commercial facilities, accounting for around 28 percent of the country’s electricity use. Or about 60% of electricity supplied to industry. Practically every organisation runs at least one motor—if not hundreds or thousands—to drive pumps, fans, air compressors, conveyors, refrigeration equipment and other processes requiring motive force. The energy consumed costs Australian industry close to $3 billion a year and produces 37 million tonnes of carbon dioxide through burning fossil fuels.
Significant cost savings can be realised by utilising higher efficiency motors, especially since running costs can be up to 100 times the purchase price of a motor over its service life. 13 Motors running continuously at high loads for long periods such as exhaust fans will tend to yield the greatest savings.
