Poyry awarded engineering services contract for 531-MW Alto Maipo hydropower project in Chile

Strabag SpA announced today it has awarded Poyry, a Finland-based international consulting and engineering company, an engineering services contract for the 531-MW Alto Maipo hydropower project.

The project includes the 267-MW Las Lajas and 264 MW Alfalfal II run-of river hydroelectric power stations located in the upper section of the Maipo River, about 50 km southeast of Santiago, Chile.

According to the announcement, Poyry will review construction plans and preliminary engineering, detail design and preparation of tender documents for hydromechanical and electrical works, operation and maintenance manuals and site supervision during installation and commissioning.

Construction on the plants began in the fourth quarter of 2013. When completed, the combined annual production is expected to be about 2,320 GWh delivered to Chile’s electrical grid, Sistema Interconectado Central.

The amount of the contract award is not immediately available, but last month HydroWorld.com reported the Alto Maipo project is estimated to cost US$2.05 billion, and is expected to be commissioned in 2019.

Strabag SpA is the Chilean unit of Strabag SE, an Austrian-based technology group for construction services. BNamericas reports the company has been active in Chile with its tunneling division since 2013 and Poyry said that it re-established offices in Chile in 2014.

In December 2016, Poyry was awarded the engineering and project management services contract for the 1.7-MW Untere Tuxbachuberleitung (Tuxbach) hydropower project, and in October, Mexican utility Generadora Fenix awarded Poyry a contract to perform studies and other prefeasibility work for a proposed hydropower project.

Details with regard to Generadora Fenix’s proposed hydroelectric plant have not been made readily available.
