Abstract

Japan Electric Power Exchange (JEPX) commenced operation on the 1st of April 2005. It provides three types of markets, i.e., a spot day-ahead market to trade the electricity that will be delivered on the following day, a forward fixed-form market to trade the electricity that will be delivered after a certain period of time, and a forward bulletin board market as a place for free transactions. This paper summarizes the role of JEPX in Japanese deregulated electricity market and its trading rules. The performance of JEPX market in the first three months is also shown.
