Electricity trading statistics for Japan were added to the ENERGY database. Wholesale spot electricity market prices for 9 Japanese regions are available, along with a table for contract buying and selling volumes. These 7-day daily data are sourced from the Japan Electric Power Exchange and start in April 2005.
Chart: Differences in electricity prices between eastern and western Japan are caused by the separation of the country's grid into two separate systems with distinct operating frequencies. Western Japan has seen more efficient nuclear reactor restarts and a higher concentration of solar power, which contributes to lower prices. Prices in eastern Japan can have a risk premium associated with the continued delays of nuclear reactor restarts. The region also relies more heavily on expensive thermal generation.
