The Macagua Dam , officially named after Antonio José de Sucre , is a dam on the Río Caroní in Ciudad Guayana in the state of Bolívar in Venezuela . The barrier is 10 km upstream from the confluence of the Caroni and Orinoco . The purpose of the dam is to generate hydropower . It was named after Antonio José de Sucre .

Barrier and power plants
The Macagua- dam is a 69 m high and 3537 m long building and consists of an embankment dam with a gravity dam sections of concrete. Three power plants are supplied from the reservoir: Macagua I (8 ° 18 '02 "N, 62 ° 39' 52" W) was built from 1956 to 1961 and has 6 * 64 MW Francis turbines / generators for an installed capacity of 384 MW . Macagua II (8 ° 18 '14 "N, 62 ° 40' 04" W) has 12 * 216 MW Francis turbines / generators with a total of 2592 MW. Macagua III (8 ° 18 '09 "N, 62 ° 40' 46" W) has 2 * 88 MW Kaplan turbines / generators with an output of 176 MW. All together form a nominal output of 3,152 MW. Macagua II and III started operating in 1996 and inaugurated in January 1997. Macagua I is currently undergoing a renovation to increase the output of the generators from 64 to 79.5 MW. The first generator was ready in 2010, the second probably in 2011 and another one year later.
For a better overview again in tabular form:
| power plant | Number of turbines / generators and their power | Overall performance | Turbine type | Installation | |
| Macagua I | 6 * 64 MW | 384 MW | Francis | 1961 | |
| Macagua II | 12 * 216 MW | 2592 MW | Francis | 1996 | |
| Macagua III | 2 * 88 MW | 176 MW | Chaplain | 1996 | |
| 3152 MW | 3152 MW |
On average, 15,200 GWh of electricity can be generated annually .
The Guri Dam (Raul Leoni) is located on the same river 81 km upstream, the Caruachi Dam (Francisco de Miranda) and the Tocoma Dam (Manuel Piar), which is under construction , 22 km upstream .
