Equipment supplier Andritz Hydro GmbH has been awarded a contract by utility Iberdrola Generacion to supply electromechanical equipment and a penstock for the 880-MW Gouvaes pumped-storage hydropower plant in Portugal.

The order, worth about US$156 million, includes the design, manufacture and installation supervision for four 220 MW turbines that will operate with a net head of 660 meters. Meanwhile, the penstock will have a total weight of about 12,000 tons, an average diameter of 5.4 meters and a length of 2.5 kilometers.

Andritz said Gouvaes will be the “heart” of a new 1,200 MW complex on the Tamega River in northern Portugal. A pair of smaller conventional hydroelectric plants will also eventually be constructed.

“Gouvaes will cover the need for peak-load energy and provide fast-responding regulating power,” Andritz said in a release. “Together with this base load generation from the other two power stations, this scheme will ideally complement the volatile electricity generation from wind power, which has been growing significantly in recent years.”
