Alstom Hydro wins contract for Grand Coulee repair work

The U.S. Bureau of Reclamation awarded a $258,017contract to Alstom Hydro for stator repair on Generator G-19 in the Third Power Plant of the 6,809-MW Grand Coulee hydroelectric project in Washington.

The work is to include removal of the faulted half-coil for delivery to the government for testing. It also includes cleaning and repair of minor damage to stator core laminations, preparing and testing a spare coil for half-coil splice, performing one half-coil splice and possibly optional additional splices.

BuRec awarded a $2 million contract in March 2009 to MWH Americas Inc. for planning and management of the proposed overhaul of six units in the Third Power Plant at Grand Coulee, on the Columbia River. The units, G-19 through G-24, are starting to experience problems stemming from age-related wear on principal components, BuRec said.

BuRec awarded another contract in 2009 to Koontz Electric Co. Inc., to furnish and install three new transformers and other equipment at Grand Coulee’s Right Power Plant.
