A journey into the heart of the Alto Maipo project


Since 2017 ATB Riva Calzoni has been established in Alto Maipo, Chile, to work on the construction of penstocks for the three vertical shafts of the Aes Gener hydropower plant.

ATB Riva Calzoni has been chosen by Strabag, Austrian general contractor, for the manufacture of S690QL grade steel penstocks - a high-strength steel with a high probability of cold cracking - of the Alto Maipo project in Chile. The hydroelectric plant, 50 kilometres from Santiago de Chile, will be able to meet a large part of the country's energy demand once completed.
