La Barrancosa Dam

The La Barrancosa Dam, formerly known as Jorge Cepernic Dam, is a concrete-face rock-fill dam being built on the Santa Cruz River about 115 km (71 mi) west of Puerto Santa Cruz in Santa Cruz Province, Argentina. It was renamed after the former governor of Santa Cruz Jorge Cepernic. A consortium led by China's Gezhouba Group was awarded the contract to build the Jorge Cepernic Dam and the Néstor Kirchner Dam upstream in August 2013. The consortium will also fund the construction. Both dams are expected to cost nearly US$4.8 billion.[1] It will be built by the firm Electroingeniería, led by Osvaldo Acosta and Gerardo Ferreyra.[2] The primary purpose of the dam is hydroelectric power generation and its power station will have an installed capacity of 600 MW.[3]
