Punta Negra Dam, Embankment dam and hydroelectric station in San Juan Province, Argentina
The concrete-face rock-fill dam extends 750 meters across the San Juan River, incorporating two Francis turbines that generate 62 megawatts of power.
The construction of Punta Negra Dam began in 2009 with 1,350 workers contributing to the project, reaching completion in August 2015.
The dam development has transformed the regional energy landscape while creating employment opportunities for local communities in San Juan Province.
The reservoir maintains a capacity of 500 million cubic meters, supporting both power generation and irrigation for 15,000 hectares of agricultural land.
The dam's intake system manages downstream water requirements while the spillway controls reservoir levels during periods of increased water flow.
