Construction contract terminated for 136-MW Nuble hydro plant in Chile

A contract between Electrica Puntilla and Vial y Vives-DSD has been terminated, meaning Vial y Vives-DSD will no longer be building the 136-MW Nuble hydro plant in Chile.

Puntilla cited differences between the two firms with regard to the contract, in a securities filing. The contract, reportedly valued at $257 million, involves construction of the intake, penstock, powerhouse and other works necessary for the plant’s commissioning.

Puntilla will be seeking a new company to take over construction of the US$350 million run-of-river plant, on the Nuble River in central-southern Biobio region. The project is expected to generate 620 GWh of electricity annually.

In the meantime, the plant’s estimated startup date has been extended to May 2018 from 2017.

The Andritz Group was awarded a US$57.4 million contract in February 2015 to supply two Francis turbines and generators, balance of plant services, control and protection equipment, and intake and diversion gates.

Electrica Puntilla, which is developing the project through a company called Hidroelectrica Nuble, has six run-of-river hydro plants and seven in the development pipeline.
