Large hydro-electric infrastructures with minimal environmental impact in Chile
450,000 homes receive power from the plant, which has an installed capacity of 155 MW and an average production of 750 GWh/year. The water is conveyed through channels and pipes to the powerhouse, which has two generator units equipped with vertical turbines.
The project involved building the powerhouse, a valve house, tunnels, water intakes, etc., using more than 100,000 concrete cubes.
ULMA Construcción Solution
ULMA supplied various auxiliary elements for this building work:
. ORMA vertical formwork, combined with EUC frames, for one-sided walls with a height of 4.8 m.
. BTM formwork shored with T-60 towers, ALUPROP and BRIO shoring, for concreting slabs of over 1.5 m thick.
. COMAIN, NEVI and BTM formwork for building vertical and horizontal structural elements.
. BRIO multidirectional formwork, configured as a ladder for worksite access.
La Higuera was registered under the Kyoto Protocol’s Clean Development Mechanism (MDL) in March 2006. It is the world’s largest hydro-electric plant to be registered and the first in Chile.
