Absperrbauwerks and power plants

The Macagua Dam is a 69 m high and 3537 m long building and consists of a rockfill dam with gravity dam sections made ​​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-Francisturbinen/Generatoren for an installed capacity of 384 MW. Macagua II (8 ° 18 ' 14 " N, 62 ° 40' 04" W) 12 * 216 MW-Francisturbinen/Generatoren together with 2592 MW. Macagua III (8 ° 18 ' 09 " N, 62 ° 40 ' 46 " W) 2 * 88 MW-Kaplanturbinen/Generatoren with a capacity of 176 MW. All together form a nominal capacity of 3152 MW. Macagua II and III were commissioned in 1996 and inaugurated in January 1997. Currently Macagua I is subjected to a regeneration in order to raise the power of the generators by 64 MW to 79.5. The first generator was completed in 2010, the second probably in 2011 and another a year later.

For a better overview again tabulated:

On average, 15,200 GWh of electricity can be generated annually.

On the same river there are 81 km upstream the Guri Dam ( Raul Leoni ), 22 km upstream of the dam Caruachi (Francisco de Miranda ) and the under construction Tocoma Dam ( Manuel Piar ).
