In May 2025, Asahi Kasei, a chemicals manufacturer that also operates thermal and hydropower generation assets for self-consumption, and Power Pool joined the Electric Power Reserve Exchange (EPRX), which runs Japan’s balancing market.
No companies were removed from the list of participants.
With that, the exchange had 93 members as of the end of May 2025.
EPRX was established on April 1, 2024, to take over the operation of Japan’s balancing market, which was partially launched in April 2021, from a cooperative of Japan’s nine mainland TSOs.
