The 20-MW Rucuy (or Ruckuy) small hydroelectric plant is now operating in the Lima region of Peru, according to grid operator COES.
The project is owned by Empresa Administradora Chungar S.A.C. and is on the Chancay River in the Chancay-Huaral river basin.
Energoproject Holding P.L.C. received contracts for work on this project in February 2014 and March 2013. Andritz Hydro supplied the equipment, including two horizontal two-jet Pelton turbines, main inlet valves and the hydraulic pressure units.
Empresa Administradora Chungar is a subsidiary of Volcan Compania Minera S.A.A., a polymetallic mining company.
According to its website: “The development and operation of Volcan's mining projects require a constant, reliable power supply to guarantee continuity of operations. In order to enhance operational reliability and reduce costs, Volcan chose to invest in its own hydroelectric generation and electricity transmission system.”
Before bringing Rucuy online, Chungar had installed generating capacity of 22 MW at 10 plants. A second Volcan subsidiary, Empresa Hidroelectrica Huanchor S.A.C., has installed capacity of 20 MW.
