Yacyreta
Location: Corrientes
Operator: Entidad Binacional Yacyreta
Configuration: 20 X 155 MW Kaplan
Operation: 1994-1997
T/G supplier: Voith, Impsa, CGE, Siemens, Toshiba, Ansaldo, Hitachi
EPC: Harza, Impregilo
Quick facts:
The Yacyreta power station is a 50:50 joint venture of Argentina and Paraguay. It was in development for almost 30 years and remains a state-owned facility despite efforts to find private investors. The EPC consortium numbered almost a dozen and built 500km of 40m closure dams plus the main dam and powerhouse facilities. In Jan 2005, the owners finally agreed the plan for boosting Yacyreta output to full design capacity. This will require raising the dam water level to 83m from its current 76m, a project that will cost at least $550mn and necessitate the relocation of 10,000 families, several industrial plants, a rail line, an airport and a harbor.
