When completed, the {{Convert|312|m|ft|0}} tall dam will be the tallest dam in the world.[2] Preliminary construction began in 2008 and the entire project is expected to be complete in 2018.[3] By April 2011, over {{Convert|200000000|m3|cuyd|0|abbr=on}} of material had been excavated from the construction site.[4] In March 2013 the China's Ministry of Environmental Protection approved construction on the dam's superstructure and associated facilities. The government acknowledged that the dam would have negative impacts on the environment but that developers were working to mitigate them. The dam is being built by the Guodian Group at a cost of US$4.02 billion.[5] The entire construction period is expected to last 10 years.[6] DesignThe Shuangjiangkou Dam, when completed, will be a {{Convert|312|m|ft|adj=mid|-high|0}} ({{Convert|314|m|ft|0}} from the foundation) and {{Convert|648.66|m|ft|adj=mid|-long|0}} rock-fill dam with a relatively impervious core. The dam's crest width will be {{Convert|16|m|ft|0}}, its elevation {{Convert|2510|m|ft|0}} above sea level. It will have a structural volume of approximately {{Convert|44000000|m3|ft3|0}}. The dam will sit at the head of a {{Convert|39330|km2|sqmi|0|adj=on}} drainage basin and have a reservoir capacity of {{Convert|3135000000|m3|acre.ft|0|lk=out}} of which {{Convert|2151000000|m3|acre.ft|0|lk=out}} is regulating or active (useful) storage. Normal reservoir elevation will be {{Convert|2500|m|ft|0}} and minimum {{Convert|2420|m|ft|0}}. Flood elevations range between {{Convert|2501|and|2504|m|ft|0}}. The dam's power station will contain four 500 MW Francis turbine-generators for an installed capacity of 2000 MW. Firm capacity of the power station is expected to be 503 MW along with the station operating for 4064 hours each year. The power station's design flow is {{Convert|1090|m3/s|ft3/s|0}} and the mean hydraulic head {{Convert|226.4|m|ft|0}}.[2] See also{{stack|{{Portal|China|Water|Renewable energy}}}}
