Salto Grande Dam
Paysandú
The Salto Grande Dam is a large hydroelectric facility situated on the Uruguay River, straddling the border between Concordia, Argentina, and Salto, Uruguay. Construction began in 1974 and was completed in 1979, marking a significant engineering achievement in the region. The dam houses fourteen Kaplan turbines, which collectively generate an installed capacity of 1,890 MW, contributing substantially to the power grids of both countries. It handles an enormous volume of water, passing approximately 64,000 cubic meters per second, far exceeding the river's average flow. The reservoir formed by the dam spans an impressive 783 square kilometers, with a length of up to 140 kilometers and a width of 9 kilometers. Beyond its functional role, the dam includes the Salto Grande Bridge, which facilitates transport across the river. The infrastructure exemplifies international cooperation and renewable energy development in South America.
