John Day Dam Turbine Runner Replacement and Generator Rewind Project - 90% Review

Goals of the project are to address decreasing reliability and efficiency of the hydroelectric generating units and to maximize the net economic benefits over the next several decades, while maintaining an acceptable level of operational flexibility, all within the hydraulic and environmental constraints imposed on the project. Economic benefits will be realized through increasing reliability and efficiency of the hydroelectric generating units after replacing existing turbines with improved fish passage turbines that provide improved power generating efficiency, rewinding the generators, and replacing and refurbishing other powertrain equipment. The design of the state-of-the-art turbines will be an iterative and collaborative process that focuses on improved fish passage design features and criteria to improve survival of turbine-passed fish. Finally, this project will decrease the risk of oil entering the water passageway and river through improved sealing technologies, design considerations for new adjustable-blade turbine runners, and the introduction of some fixed-blade turbine runners.
