Curillinque Hydropower Station

Curillinque hydropower station in Chile is owned by Enel. The station was commissioned in 1993 and was equipped with one Francis turbine of 89 MW at a net head of 114 meters. 

In 2021, Aker Solutions was awarded a contract for model testing and upgrading of the unit. The goal was to improve operation stability over a larger power range. The station had previously been experiencing severe vibrations at higher outputs. After model testing and replacement of most non-embedded parts, the unit was recommissioned in 2023.

Following the upgrade, the unit could operate over a large operation area, with no severe vibrations, enabling improved operational flexibility.
