River course
The Río Hercca forms the outflow of the Laguna Langui Layo lake . The outflow has been regulated by a weir since 2002 . The Río Hercca flows 10 km in a north-northwest direction, where it has smaller river bends. It then turns in the east-northeast direction and cuts through several transverse ridges. Finally it flows into the Río Vilcanota on the southern outskirts of Sicuani .
The catchment area of the Río Hercca covers about 616 km².
Langui hydropower plant
At river 14.3 there is a weir ( ⊙ ) on the river. On the right bank of the river, a 1,800 m long canal with an adjoining pressure line leads to the Langui hydropower plant ( ⊙ ). This is located on the right bank of the river at river kilometer 12.5. The power plant, built in the early 2000s, is operated by Central Hidroeléctrica de Langui SA. In the mid-2010s, the power plant was expanded to include a further unit (Langui II). The hydropower plant now has three horizontally directed Francis turbines with an output of 736 kW, 2500 kW and 3027 kW. The fall height is between 115.7 and 119 m. The expansion water volume after the expansion is 6.3 m³ / s, the total capacity is 6386 kW, the annual energy production is 36,250 MWh.
