The technical specifications necessary for the realization of this project are currently being updated.
This project aims at utilizing the La Palca river for power generation via a small, open-air dam and a fairly long tunnel, giving us a 500 meters head. The 37 MW plant would reside in a cavern and contain a Pelton turbine with a vertical axis and an annual output of 196 GWh.
The overall design includes a penstock and a surge tank. The gorge formed by the river is an interesting formation that allows us to analyze the project in terms of its potential.
