WALLA WALLA, Wash. — The Corps of Engineers has awarded a $64 million contract to Andritz Hydro to rewind 10 generators at McNary Lock and Dam on Oregon’s Columbia River.
Work on the 980-MW plant is expected to be completed in 2014, as two installations will be completed each year over the next five years. The work will involve Units 1 through 4 and 7 through 12.
Among other things, Andritz will design, manufacture, and deliver stator bars and accessories; disassemble and reassemble generators; remove old stator coils; install and test new stator windings and accessories; remove old turbine shaft sleeves and install new shaft sleeves on each unit; furnish, install, and test new switches, temperature read-outs, and automatic control of unit heaters for ten units; and remove and dispose of existing rotating exciters.
