The Macagua Dam, officially known as Antonio José de Sucre, is an embankment dam with concrete gravity sections on the Caroní River in Ciudad Guayana, Bolívar State, Venezuela. It is 10 km (6 mi)upstream from the confluence of the Caroni and Orinoco Rivers, 81 km (50 mi) downstream of the Guri Dam and 22 km (14 mi) downstream of the Caruachi Dam. The dam's main purpose is hydroelectric power generation and it was later named after Antonio José de Sucre.
Dam and power plants
The Macagua Dam is a 69 m (226 ft) tall and 3,537 m (11,604 ft) long embankment dam with concrete gravity sections for each of the three different power stations. Macagua I was constructed from 1956 to 1961 and it contains 6 x 64 MW Francis turbine-generators for an installed capacity of 384 MW. Macagua II contains 12 x 216 MW Francis turbine-generators for an installed capacity of 2,592. Finally, Macagua III contains 2 x 88 MW Kaplan turbine-generators for an installed capacity of 176 MW. All together, the generation capacity is 3,152 MW. Both Macagua II and III were operational in 1996 and inaugurated in January 1997. Currently, Macagua I is undergoing a refurbishment in order to increase the capacity of each generator from 64 MW to 79.5. The first generator was complete in 2010, the second is expected to be completed in 2011 and another each year thereafter.
