Yacyretá

Yacyretá is a large hydroelectric power plant located on the Paraná River, straddling the border between Argentina and Paraguay. Its construction began in 1983 and the first generator was commissioned in 1994. The dam is a significant source of electricity for both countries. The name Yacyretá comes from the Guaraní language and translates to "the sound of the moon".

The Yacyretá Dam is an earth-fill dam with concrete spillways. The reservoir created by the dam covers a substantial area, impacting local ecosystems and requiring the relocation of communities. The project is managed by the Yacyretá Binational Entity (EBY), a joint Argentine-Paraguayan organization.

The power generated by Yacyretá is divided between Argentina and Paraguay, though Paraguay has historically utilized a smaller portion of its share. The plant's operation has been a subject of international agreements and negotiations regarding water usage, environmental impact, and energy distribution. Its vast scale and binational nature make it a complex and important infrastructure project in South America.
