Hydroelectric power stations of Selga de Ordas, Carbonero and La Breña II

Spain

IDOM has provided different engineering services for dams located in the provinces of León and Córdoba, such as:

1. Detailed engineering for the La Breña II project, located in Almodóvar del Río (Córdoba), for Dragados, Obras y Proyectos, with the following characteristics:

• Typology: Gravity, HCR
• Maximum height on foundations: 124 m
• Water volume: 800 m³
• Crowning Length: 685 m
• Crowning Width: 10 m
• Concrete volume: 1,500,000 m³
• Excavation volume: 900,000 m³

The project included the realization of a three-dimensional thermal-tension model and the emergency plan against overflows and floods.

2. Previous studies, Draft and Environmental Impact Study of 3 dams on the Eresma and Moros rivers: Carbonero, Guijasalbas and El Tejo.
