GE rewinds hydro generator

January 22 2004 – GE Energy received a contract of more than $540 000 from the Imperial Irrigation District (IID) for a hydro generator rewind project at an IID hydroelectric plant on the All American Canal near El Centro, California.

GE designed, supplied and installed a new 6.9 kV stator winding for the 37-year-old Allis Chalmers generator at the plant. The old stator and field poles were tested and determined to be suitable for continued duty. The work was completed in early January, with the 5 MW hydro plant scheduled to return to commercial operation in February, 2004.

The new stator winding was manufactured by GE in Brazil, with project engineering handled by GE in Canada. IID is the largest irrigation district in the nation. It also is the sixth largest power utility in California, serving more than 110 000 customers in the Imperial and Coachella valleys and portions of San Diego County. The community-owned utility operates 14 hydroelectric units at seven sites located on the All American Canal, which draws its water from the Colorado River near Yuma, Arizona.

The water is transported to the Imperial Valley in southern California and is used primarily by the region’s farmers for crop irrigation. IID’s installed hydroelectric generation capacity totals 84 MW.
