The tallest Dam in the world will be at China

The Jinping-I Hydropower Station (also known as the Jinping-I Dam, Jinping 1st Cascade or Jinping No.1 Hydraulic Power Station) is a large hydroelectric project on the "Jinping Bend" of the Yalong River (Yalong Jiang) in Lingshan, Sichuan, China. Construction on the project began in 2005 and when complete, it will have a 3600 MW capacity to produce between 16 and 18 TW-h (billion kW·h) annually. Supplying the power station will be a reservoir created by a 305-metre-tall arch dam, the tallest in the world. The project's objective is to supply energy for expanding industrialization and urbanization, improve flood protection, and prevent erosion. The dam began to impound its reservoir on 30 November 2012 and the first two of six 600 MW generators became operational on 30 August 2013.  Full electrical power capability will not be installed until 2015.
