The financial details of the contract have not been disclosed. As part of the contract, Pöyry will review the constructability and preliminary engineering, detail design and preparation of tender documents for hydromechanical and electrical works.

The company will also provide operations and maintenance (O&M) manuals and site supervision services during the construction and commissioning phase of the project.

The Alto Maipo hydropower project will include two run-of-the-river hydroelectric plants.

Construction on the 267MW Las Lajas plant and 264MW Alfalfal II plant began in the fourth quarter of 2013. They are expected to be commissioned in 2019.

When completed, the combined annual production is estimated to be about 2,320 GWh delivered to Chile's electrical grid, Sistema Interconectado Central.

Pöyry Chile country manager Patrick Furrer said: "This assignment further strengthens Pöyry's position as one of the world's leading hydropower engineering consultancies. Our approach, combining local engineering know-how with international expertise is very well received by clients.

“After re-establishing Pöyry's office in Chile in 2014, this is an important milestone in delivering locally-provided engineering services. We are pleased by the trust Strabag has shown in Pöyry and look forward to developing our excellent relations, especially in a project as challenging as Alto Maipo."

Pöyry is already working with Strabag subsidiary, Züblin International, providing engineering services for the La Mina hydropower project.

Last December, Pöyry was awarded a similar engineering services assignment contract for the Untere Tuxbachüberleitung hydropower project in Austria by Verbund Hydro Power.
