# Salto Grande hydroelectric complex operations and finances > Live situation record from CLSTR: https://clstr.news/situations/salto-grande-hydroelectric-complex-operations-and-finances > Updated: 2026-10-25T22:48:03.000Z. Sources: 5. Developments: 2. The Salto Grande hydroelectric complex, a binational project between Argentina and Uruguay, is approaching its 80th anniversary. While the dam has historically served as a vital energy link, its legacy includes environmental and social costs, such as the flooding of 30,000 hectares and the relocation of the city of Federación. Recent developments highlight a significant increase in economic resources flowing to the Entre Ríos region in Argentina. Senator Rubén Dal Molín reported that hydroelectric royalties and operating surpluses for municipalities like Federación and Santa Ana have seen a substantial real-term increase. This growth is attributed to the recomposition of electricity generation tariffs following negotiations between provincial, national, and binational authorities. These funds are intended for local infrastructure projects, even as the complex prepares for a major historical investment to replace and repair its turbines. ## Timeline ### 2026-10-25: Salto Grande hydroelectric funds see significant increase in Entre Ríos Senator Rubén Dal Molín reported that hydroelectric royalties from Salto Grande in Entre Ríos have nearly doubled in real terms for 2025 compared to 2023 levels. 2 sources. https://clstr.news/cluster/salto-grande-hydroelectric-funds-see-significant-increase-in-entre-ros ### 2026-10-24: Salto Grande Dam marks 80 years of regional energy history Marking 80 years since the 1946 agreement, the Salto Grande dam faces both historical significance and criticism regarding its social, environmental, and economic impacts on the Argentina-Uruguay border. 3 sources. https://clstr.news/cluster/salto-grande-dam-marks-80-years-of-regional-energy-history --- Cite as: Salto Grande hydroelectric complex operations and finances.
