One of the fundamental problems affects the performance of pumping stations is its relative high operational cost. As three-phase induction motors are the main prime mover of pumping stations and considered the most widely used electrical motors due to their reliability, ease of maintenance. However, its major problem is the low power factor which results in high electric energy consumption. Energy will be saved when power factor is improved. The main objective of this paper is studying the power factor improvement in El sadaa Pumping Station because of its low operating efficiency which goes from 20 % to 25 %and calculating penalty, ponus and savings in each cases. The correction is achieved by the addition of capacitor banks in parallel with the connected motor circuits and can be applied to the starter, applied at the switchboard or the distribution panel. A model of this station is created using Matlab TM  Simulink. Then the determination of induction motor parameters is performed. The station model is discussed. From the simulation results, the power factor enhancement of the pumping station is highlighted.
