Upper and Lower El Mañío Hydroelectric Power Plants
We participated in the feasibility studies, engineering support for EIS processing, DGA project, detailed engineering, construction management and supervision, and commissioning of the hydroelectric power plants.
Client: Sociedad Hidroeléctrica río Conquil, S.A.
Location: Panguipulli, Chile
Date (Year): 2015 - 2018
The Mañío project harnesses the hydroelectric potential of the Conquil River, located near Panguipulli in the Los Ríos region. The project consists of two hydroelectric power plants in a chain. The upper Mañío is sized for a flow of 2.75 m³/s, overcoming a 212 m difference in level and developing a power of 4.8 MW. The lower Mañío is sized for 4.0 m³s, with a gross head of 70 m providing a power output of 2.4 MW.
Both plants feature a conventional intake, open channel, load chamber, penstock, penstock and powerhouse design. The upper head is equipped with a vertical axis Pelton turbine, while the lower head has two horizontal Francis turbines.
