Reclamation awards switchgear retrofill for 19.5-MW Headgate Rock

Reclamation also awarded a $420,644 contract to Siemens Industry Inc. to retrofill low-voltage station service switchgear at the Bureau of Indian Affairs' 19.5-MW Headgate Rock Dam in Arizona.

The agency took bids for that work in June.

Siemens Industry, of Buffalo Grove, Ill., is to perform a retrofill, replacing existing breakers, operating controls and other components, specially designed so that they fit within existing racks.
