Proyecto hidroeléctrico Potrero del Clavillo, Hydroelectric project in Tucumán, Argentina.
Proyecto Hidroeléctrico Potrero del Clavillo is a water power facility spanning the provinces of Tucumán and Catamarca, featuring a main reservoir, several diversion dams, and three generating stations. The installation harnesses water from the Las Cañas River to produce electricity while supplying irrigation and industrial water sources.
Construction began in 1974 but ground to a halt in 1976 when the military government reallocated funding toward different infrastructure priorities. This interruption delayed the full development of the complex for decades.
The project represents a substantial infrastructure development within the Belgrano Plan, aimed at advancing the northern regions of Argentina.
The project spans a region across two provinces with multiple facilities distributed along the river course. Access to certain infrastructure components may be restricted, so advance planning is recommended for anyone wishing to view the site.
The main reservoir captures water from Las Cañas River at its entry point to Tucumán, with a total storage capacity of 109.2 cubic hectometers.
