Abstract :
The deregulation of electric power utilities has been progressing all over the world including Japan. Therefore, it is useful for coming full liberalization to analyze current market price and its structure. In this paper, we analyze the market prices of JEPX (Japan Electric Power Exchange) by simple regression equations, of which explanatory variables are a value related to demand and the power price of 24 hours ago. The results of JEPX price data compare with the results of New England electricity market price data. Furthermore, as the regression analysis for the winter peak period is not good, we add temperature or crude oil price data as a new explanation variable to improve the coefficients of determination.
