This project is formed jointly with the Central Hidroeléctrica Simón Bolívar in Guri, Antonio José de Sucre in Macagua and Manuel Piar in Tocoma (under construction), the development of Lower Caroní River hydroelectric resources and one of the world's largest hydro projects now in construction, that, when completed, EDELCA (Electrificación del Caroní CA) claims will save Venezuela the equivalent of 750,000 barrels of oil per day, compared to 300,000 currently.

[2] The contract for the design, supply and installation of the main electro-mechanical equipment was awarded to a consortium of Kvaerner of Norway, GE Energy of the US, and Elin Transformatoren GmbH of Austria.

A total of 12 Kaplan turbine-generator units, each capable of a power output of 180 MW, were supplied to the project.

A 900 m right-abutment rockfill closure dam has a concrete slab face and a maximum height of 50 m, and a 4,200 m left-abutment earth and rockfill closure dam has a maximum height of 45 m. A spillway with nine spans and radial surface gates has an aggregate 30,000 cubic metres per second (1,100,000 cu ft/s) flow capacity.

The 238 square kilometres (92 sq mi) reservoir has a normal operating elevation of 91.5 metres (300 ft) above sea level.
