The project, started in 2006, includes the installation of 2,320 megawatts (3,110,000 hp) MW to generate annual average energy of 12,100 gigawatt-hours (44,000 TJ).

[3] The project was awarded to OIV consortium, consisting of Odebrecht (50%), Salini Impregilo (40%) and Vinccler (10%),[4] with an initial budget US$3,061 mil.

[5] Ten Kaplan generator units, of 230 megawatts (310,000 hp), manufactured by an Argentinian company IMPSA [es], were predicted to begin operations between 2012 and 2014.

[6] These units had the world record as of 2012 in power generation at nominal head for Kaplan turbines.
