Spain - Castrelo

In February 2015, ANDRITZ HYDRO was awarded a contract from Ferro Atlántica S.A. for the replacement of the spiral casing of all three units and the rehabilitation of turbine, generator, and auxiliary equipment at Castrelo hydropower plant in Spain.

HPP Castrelo is located at the Ezaro River. It was originally put into operation in the 1950s and has a total output of 40 MW.

The rehabilitation project will be executed by a team from ANDRITZ HYDRO Spain. The scope of supply includes the generator rehabilitation, rotor and stator cleaning, as well as the corrosion protection for the new spiral cases. It further comprises the rehabilitation of the turbine, the generator and the auxiliary equipment.

Shop work for the first unit began in April 2015 and is due to be completed within nine months.
