Electric Power Development Co., Ltd. (J-POWER), has completed the modernization (renovations) of the main facilities, including the water turbine and generators, at Suezawa Hydroelectric Power Station (Uonuma City, Niigata Prefecture, Japan). The modernization work began on April 19, 2023 and the station commenced commercial operation recently.
Having operated for over 60 years since its initial startup in 1958, Suezawa Hydroelectric Power Station underwent modernization work to update its aging main facilities, including the water turbine and generators. This modernization work increased the power output by 700 kW from 1,500 kW to 2,200 kW through the installation of a new water turbine runner (developed inhouse) and an increase in the maximum water intake.
