The Yanango hydropower plant (span. Central Hidroeléctrica Yanango ) is located on the Río Tarma in central Peru . The power plant is located in the San Ramón district in the Chanchamayo province of the Junín administrative region . The facility is operated by Enel .
Hydroelectric power plant
The hydropower plant, which went into operation in February 2000, is located on the right bank of the Río Tarma. It is located in the Peruvian Central Cordillera 14 km west-southwest of the city of San Ramón . The Yanango hydropower plant forms the second lowest level of a power plant cascade on the Río Tarma - the Carpapata III hydropower plant is upstream and the La Vírgen hydropower plant downstream .
The power plant project cost $ 51 million. Graña y Montero and the consortium ABB Generación / De Pretto-Escher Wyss were involved in the construction.
The power plant has a vertically directed Francis turbine with an output of 43 MW. The height of fall is 242 m, the volume of water removed is 20 m³ / s. The annual energy production is 228 GWh.
Weir
Almost 5.5 km upstream there is a weir ( ⊙ ) with a sedimentation basin on the Río Tarma . Almost 2 kilometers below the weir, the Río Yanango flows into the Río Tarma on the right. The water is led through the right slope of the valley to a pressure pipe. This runs above ground down the slope to the power plant. There is a substation next to the power plant.

Yanango radiation accident
On February 20, 1999, there was a radiation accident on the construction site. A welder was working on a weld seam there when a radiologist wanted to carry out a radiological examination of the tightness there as well. A special device for this purpose included a radiation source consisting of the iridium - isotope 192 Ir, which was housed in a metal housing. Due to a delay, the device was left unattended for several hours. During this time, under circumstances that were not fully clarified, the welder took the radio source and kept it in his pocket. The absence and whereabouts could not be clarified until the following night. The worker had meanwhile sustained severe radiation injuries. He came to Lima for treatment and later to France. Multiple radiation necrosis developed on the legs and buttocks. Eventually the right leg had to be amputated.
