Renewable Generation Curtailment in Japan
Japan’s increasing non-dispatchable renewable capacity is leading to increasing output curtailment. Solar generation was curtailed for the first time in October 2018 and wind generation followed a month later, both in Kyushu.
While Kyushu remained the only TSO area with curtailment until FY2021, in FY2022, Hokkaido, Tohoku, Kansai, Chugoku, Shikoku, and Okinawa areas experienced curtailment too. With Hokuriku and Chubu joining in FY2023, Tokyo area remains the only one with zero renewable generation curtailment to date.
