Problem A The water pumping station in a desalination on Western cost of Saudi Arabia has 9 standard efficiency (IEI) induction motors, of which 7 are operating around the clock, i.e. every day of the year, 24 hours each day. The other two motors are kept standby. The motor specifications are as below: 3-phase pole 50 H.P. 660V 60Hz 1767 rpm 91.25% Nominal Efficiency PF 0.85 lagging An electrical energy auditor suggests replacing the motors with Ultra-Premium efficiency motors (IE4), having an efficiency of 95.25% and power factor of 0.88 lagging. 1. Calculate the savings in annual Electricity cost for operating the motors bank after implementing Energy Management Opportunities (EMO) suggested by the auditor.
