The Medog Hydropower Station (Chinese: 墨脱水电站) or Motuo Hydropower Station is a planned 60,000 megawatt (MW) hydroelectric dam project under development on the Yarlung Tsangpo river in Tibet Autonomous Region, China. Upon completion, it will become the world's largest hydropower facility, with an anticipated annual power generation capacity of 300 billion kilowatt-hours—triple that of the Three Gorges Dam. The Chinese government authorized the dam's construction in December 2024, with an estimated investment exceeding 1 trillion yuan (approximately US$137 billion). The project is intended to be developed as a single-phase installation, with commercial operations planned for 2033.
