Korea, Hopeless Country Per capita GDP is less than 100 dollars. The ratio of unemployed people accounts for more than 25% of total labor population. Power generation facilities stand at only one-sixth of those of Mexico. Export is hovering around 2 million dollars, whilst import exceeds 200 million dollars. All these figures indicate that Korea s economic miracle would never happen

Strong Public-Private Partnership - Voltage conversion & simplification (220V / 22.9kV) - Standardization of technical specification - Special law and regulation to facilitate the rural electrification - Push on power development under strong leadership Emphasis on Training and Knowledge Sharing - Employee training in the technologically advanced organizations - Joint study & information exchange with developed countries - Huge and steady investment in H.R.D Relatively Clean and Transparent Organization Culture
Knowledge and Experience Sharing Mechanism Employees could learn know-hows and skills from experts in KEPCO Academy KEPRI (KEPCO Research Institute) played a significant role in sharing and disseminating information on new technologies KEPCO Employees Higher Loyalty to Their Organization Work-oriented mindset stemmed from life-long employment system Tend to consider themselves as the owner of the company rather than being employed by the company Peaceful and Constructive Labor-Management Relationship Maintain communication channel between Labor Union and Management Partnership based upon trust, cooperation, concession and mutual understanding
Based upon discussions so far we can come to conclude that KEPCO has successfully overcome a variety of challenges in developing its technologies and skills over the past 4 decades and has made itself one of the world-leading power companies. KEPCO wishes to share knowledge and experience and transfer technologies and skills to people living in developing countries to help ease their sufferings from the shortage of electric power. Through these supportive and contributive activities, KEPCO will continue to play a pivotal role in not only enhancing the quality of life but also bringing our fellow people more prosperous and brighter future.
