It is 32 km (20 mi) downstream of the Longyangxia Dam and 73 km (45 mi) upstream from the Lijiaxia Dam. The main purpose of the dam is hydroelectric power generation and it supports the largest station in the Yellow River basin. The facility generates power by utilizing six turbines, each with a generating capacity of 700 MW, totaling to a capacity of 4,200 MW.

Construction

By the beginning of 2004, the Yellow River was diverted and in September of that year, excavation on the dam's abutment began. In April 2006, the first concrete was cast and on May 18, 2009, the power plant's first two generators were commissioned. A total of 79,571,000 m³ (2.8100×10⁹ cu ft) of earth and rock were excavated from the dam site.[1][2]
