U.S. awards ABB exciter replacement contract for Libby Dam hydro project

The Corps of Engineers has awarded ABB Inc. a $2.4 million contract for replacement of five excitation systems at 525-MW Libby Dam on the Kootenai River in Montana.

The Corps seeks design, supply and installation of five excitation systems at Libby, including removal of existing static exciters, repairing the concrete floor and installing and testing new units. New units are to include automatic voltage regulators, power system stabilizers and power potential transformers.

Recently, ABB announced it has completed a comprehensive project to provide power equipment for the AmerenUE Taum Sauk pumped-storage hydro plant in Missouri.
