La Barrancosa Dam
Dam in Puerto Santa Cruz, Santa Cruz Province
From Wikipedia, the free encyclopedia
The Complejo Hidroeléctrico Cóndor Cliff (ex-N.K) y La Barrancosa (ex G.J.C.) 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. A consortium led by China's Gezhouba Group was awarded the contract to build the Condor Cliff & La Barrancosa Dam upstream in August 2013. The consortium will also fund the construction. Both dams are expected to cost nearly US$4.8 billion.[1] The dam is being built by Eling Ingeniería, the successor of Electroingeniería of 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]

In July 2015 machines arrived in Santa Cruz for the construction of the dams.[4]
In December 2023 construction was stopped awaiting funding from China.[5]El 18 de julio de 2025 se firmó un entendimiento con las empresas y el gobernador Claudio Vidal para reactivar la construcción de una de las represas de Santa Cruz, una obra de casi US$5000 millones. En diciembre del 2025, se efectivizaron la transferencia de 150 millones de dólares a la empresa China Gezhouba Group, un paso clave para poner nuevamente en marcha una de las represas del complejo Hidroeléctrico en el Río Santa Cruz, Cóndor Cliff – La Barrancosa, que se construye sobre el río Santa Cruz, paralizado desde 2023.[6]
