1 Handbook of Electricity Statistics in Korea (As of Dec. 2008) 2009

2 Preface As a non-profit, independent organization established in April 2001, Korea Power Exchange (KPX) has been successfully operating Korea's Electricity Market and Power System. The Korean power market is fast emerging as a world-class power market, with its 302 members, annual trading value of as much as KRW 26.8 trillion (USD 35.1 billion), and power generation facilities with capacity of 72,491 MW (as of Dec. 2008). Since KPX was appointed as an official management organization of national power statistics by the government in July 2003, KPX has been gathering all the power statistical data from every power-related company and managing the data on a computer system. KPX is also providing information services at EPSIS ( where you can find reliable and up-to-date data of Korean Electricity Industry. It is our hope that this handbook will provide you with useful information and better understanding of the electricity industry statistics of Korea.
