The European Energy Exchange (EEX) will extend exchange order book trading to fully cover Asian-Pacific business hours on its Japanese power derivatives market from 7 September 2026, building on strong growth since market launch and responding to increasing demand from participants in the region.
Exchange trading via the central order book has been available for over a year during a two-hour window from 16:00 to 18:00 JST, while registration of transactions for clearing is already possible during full Asia-Pacific business hours (09:00–18:00 JST). From 7 September onwards, EEX will extend exchange order book trading to cover the full Japanese business day, applying to both futures and options contracts across
all available maturities and market areas, including Tokyo, Kansai and Chubu. Additionally, all trades on this market, whether executed via the central order book or registered through brokers, will be immediately
processed for clearing through European Commodity Clearing (ECC) and made publicly available through EEX's data feeds.
Steffen Köhler, Chief Commercial Officer of EEX, comments: “Extending order book trading to cover the full APAC business day is a natural next step in our commitment to building a transparent, trusted and robust
market for Japanese power, and further supporting liquidity and price formation. We will continue to develop the market in close dialogue with Japanese and international market participants, regulators and industry
partners, ensuring our offering meets the evolving needs of the APAC trading community.”
Bob Takai, CEO of EEX Japan, adds: "These developments mark an important milestone for the Japanese power derivatives market. Having an electronic order book open during the entire Japanese business day
provides market participants not only with extended opportunities to execute trading strategies, but, more importantly, it also ensures greater transparency in this rapidly growing market."
Over the past six years, EEX’s Japanese power derivatives market has expanded significantly year-on-year, with over 110 TWh already traded in 2026, compared to the total traded volume of 150 TWh in 2025.
Key milestones during the development of this market included the gradual extension to multiple Japanese market areas, the successful introduction of options, daily and fiscal year futures contracts. The order book
facility was launched in spring 2025, through which traded volumes have been steadily increasing, with the Year-to-Date level nearly reaching the full volume of 2025.
