More than 130 years have already passed since the arrival of electric power in Chile and in 1908 ANDRITZ successfully commissioned its first plant in the country. Since then, ANDRITZ has delivered more than 140 generating units in Chile with a combined capacity of more than 2,400 MW.

In recent decades ANDRITZ has also modernized more than 50 units with a total output of more than 1,450 MW. Among these references are large hydropower plants that continue to play an essential role in Chile's electricity system. These plants include Pangue (568 MW), El Toro (484 MW), Alfalfal I (188 MW), Higuera (182 MW), Rucue (180 MW), and Chacayes (130 MW). ANDRITZ has also successfully participated in numerous small hydroelectric power plant development projects, as well as in hybrid irrigation and generation projects like Embalse Ancoa, Embalse Convento Viejo, and Embalse Digua where the water supply for farm irrigation is combined with power generation for the grid. ANDRITZ has also participated in the construction of substations for the national grid and in tenders for equipment to support grid stability and strengthening.
Despite the lack of new hydroelectric investment projects in Chile in recent years, ANDRITZ has had many successes in the modernization of existing plants. These include projects such as the hydropower stations Antuco, Pangue and Pehuenche, Blanco, and Queltehues, new butterfly valves for Ralco, spherical valves to protect the penstocks of the Alto Maipo complex, and the centralized remote monitoring and control systems for all the plants in the Aconcagua Valley for one of our customers. These successes came alongside service activities to support customers in scheduled and emergency maintenance of their plants, component recovery and restoration in our Colina workshop. In addition, predictive monitoring services were delivered from our Operations and Maintenance division to support customer operations.
