Important point about this dam
  • The dam is a 289-meter-tall (954-foot-tall) double-curvature arch dam, having 16 generating units.
  • Each unit will have to generate a capacity of 1 million kilowatts, making it the second biggest in size after the “Three Gorges Dam” opened in 2003 on the Yangtze, with 22.5 million kilowatts of generating capacity.
  • Through the Baihetan Dam, the Chinese government aims to curb surging fossil fuel demand by building more hydropower capacity. Hydropower is losing support in other countries due to complaints dams flood communities and farmland and disrupt the ecology of rivers, threatening fish and other species.
  • Both the dams have been built by the state-owned Three Gorges Group Corp., the world’s biggest investor in hydro, solar, and wind generation.
