Power factor improvement

An industrial user has a number of machine tools which are driven by three phase induction motors. during a particular shift, the power factor of the combined load can vary between 0.65(100 KVA load) and 0.81 (20 KVA) load. the user is contemplating using a capacitor bank to maintain the power factor at the point the 11KV supply enters the factory at 0.94. Calculate the KVAr rating range of the capacitors required to achieve this.

Could you also please discuss the economic considerations that must be taken into account before the user makes a firm decision as to whether he is going to implement a power factor correction system.
