The El Chocón Dam (Template:Langx) is the fourth of the five dams on the Limay River in the northwestern Argentine Patagonia (the Comahue region), at Script error: No such module "convert". above mean sea level. El Chocón Cerros Colorados is on the Limay River at about Script error: No such module "convert". upstream of its confluence with the Neuquén River.
El Chocón Cerros Colorados is used to regulate the flow of the Limay River, for irrigation, and for the generation of hydroelectricity. Its power station is the largest hydroelectric power plant in Patagonia, with a capacity of Script error: No such module "convert".. It was built by the state-owned company Hidronor (Hidroeléctrica Norpatagónica). It started operating in 1973 and achieved full capacity in 1978. In the period 1974–1995, it produced an annual average of Script error: No such module "convert".. In 1993 it was privatized, with an exploitation concession granted to Hidroeléctrica El Chocón S. A.
While the formal name of the project is Embalse Ezequiel Ramos Mexía, in common use it ended up acquiring the name of the settlement that served as the construction's base of operations, Villa El Chocón (a small town, population 957, as of 2001).
El Chocón is part of a larger engineering scheme that also includes the Cerros Colorados Complex, on the Neuquén River. The Hydroelectric Complex which holds El Chocón and Arroyito Hydroelectric Power Plants, is located in the region known as Comahue, which is formed by the Argentine provinces of Río Negro and Neuquén and the southern area of the Buenos Aires and La Pampa provinces.
Technical details
The dam is made of earth, with a concrete spillway. About Script error: No such module "convert". of materials were used. It measures Script error: No such module "convert". in length. Its maximum height over the river bed is Script error: No such module "convert"..
The reservoir has a maximum area of Script error: No such module "convert"., a mean depth of Script error: No such module "convert". (maximum Script error: No such module "convert".), and a maximum volume of Script error: No such module "convert".. It is used for sailing, sport fishing and other forms of recreation by locals and tourists.
The power plant has six vertical Francis turbines, with a nominal power of Script error: No such module "convert". each, which rotate at 88 rpm. The apparent powers are 200 MVA for each generator and 180 MVA for each transformer.
