Huanza Hydroelectric Plant

The hydroelectric plant is located in Huarochirí, Lima and provides energy supply from clean and renewable sources

2009 - 2012


Project description:

The hydro-energy project is owned by CONENHUA, a subsidiary of Grupo Buenaventura – it is located at 4,100 meters above sea level in the district of Huanza, department of Lima, and was developed thanks to the Río Pallca Consortium.

One of the most important characteristics of this project is that it was tendered as a single package and for a single contractor, giving the opportunity to construction engineers to interrelate criteria, optimize the use of resources between the different works (synergy) and not having to depend on third parties to be able to advance the execution of some works.

  • Permanent access routes to the project, concrete dam, water intake, 10km conduction tunnel with 3.7m diameter, 4.7km low pressure conduction pipe, balance chimney, forced pipe with 700m drop and a house of surface machines for 2 Pelton turbines.
