The Nigeria power system has been undergoing several policy changes over the years in order to improve the power system and also to ensure increase in capacity and efficient electricity supply to Nigerians. However, these laudable goals are yet to be achieved and thesmallmegawatts that Nigeria generates iswasted by high reactive loads in many industrial sectors today by operating on low power factor. The aimof this research paper is to demonstrate the impact of power factor correction on energy saving in Nigeria power system. It was realised by installing power factor correction device (PFCD) in some selected consumer’s premises and field measurement was carried out before and after the PFCD installation.Datawere recorded during the operating hours of the selected factory site. Conclusively, it was shown that the power factor of the selected factory site was improved from 0.7 to 0.97, thereby increasing the KVA capacity of the electricity supplying transformer by 27.84%.The analyses of the results shows that the PFC device have the ability to reduce the system losses, improve the capacity and the efficiency of the system without installing additional cables and transformers, thereby saving energy for Nigeria.
