Acaray Dam — 210 MW Hydro

The Acaray Dam is a crucial player in Paraguay’s energy sector, ranked as the 3rd largest power generation facility in a nation where hydroelectric capacity dominates, contributing 2.40% to the country’s total of 8,760 MW. This facility, with a capacity of 210 MW, is uniquely positioned among just three plants in Paraguay, all of which rely on hydroelectric technology. Commissioned in 1981 and operated by the Administracion Nacional de Electricidad, Acaray Dam exemplifies the utilization of river systems for sustainable energy generation. It is located near the Itaipu Dam, which boasts an impressive capacity of 14,000 MW, making it the largest hydroelectric plant in the world, followed by Itaipu’s Brazilian counterpart at 7,000 MW and the Paraguay section of Itaipu Binacional also at 7,000 MW. This proximity to such monumental facilities not only amplifies the importance of Acaray Dam but also highlights the concentration of hydro power resources in this region. Compared to an average capacity of 2,920 MW per plant across the three facilities, Acaray Dam’s output reflects its strategic importance in balancing supply within a hydro-dependent grid. Paraguay’s energy profile is characterized by its near-total reliance on hydroelectric power, making Acaray Dam an integral component of the national infrastructure, especially as the country strives to meet increasing energy demands. With the global focus on renewable energy, Acaray Dam is positioned to play a vital role in supporting Paraguay’s sustainable development goals while ensuring energy security and economic growth.
