The Callahuanca hydropower plant (Spanish: Central Hidroeléctrica Callahuanca ) is located in the Peruvian Western Cordillera on the Río Santa Eulalia in the central west of Peru , 50 km east-northeast of the state capital Lima . The power plant is located in the Callahuanca district in the Huarochirí province of the Lima administrative region . The facility is operated by Enel .
Hydroelectric power plant
The hydropower plant was built in 1934–1938. The first unit went into operation in 1938. The power plant is equipped with 4 horizontally aligned Pelton turbines . The total installed capacity is 82 MW. The average annual energy production is 600 GWh. The power plant uses a gross drop height of 435 m. The expansion water volume is 23 m³ / s. There is an expansion tank ( ⊙ ) above the power plant . From this, four pressure lines about 1 km long lead down to the power plant. The water is fed into the Río Santa Eulalia directly below the power station. At a nearby weir , the water is diverted from the river again and fed to the Moyopampa hydropower plant.
Three of the turbines were replaced with new ones in 2005. In 2017, landslides occurred as a result of heavy rain events caused by the El Niño weather phenomenon . This led to considerable damage to the power plant, so that it had to be temporarily shut down. The company Andritz Hydro was to restore the plant commissioned. As part of this measure, the fourth turbine is to be replaced by a new one.
Huinco dam
The Huinco Dam ( ⊙ ) is located 9.7 km upstream on the Río Santa Eulalia. The dam is 26 m high and 80 m wide. The storage volume is 215,000 m³. An approximately 8 km long aqueduct leads from the dam to the expansion tank of the Callahuanca power station.
Feed from the Río Rímac
Below the Matucana hydropower plant ( ⊙ ) on the Río Rímac , the water is routed to the Callahuanca hydropower plant's expansion tank via an 18 km pipeline.
