2009 Steel Pipeline and Pipe Fabrication Project of the Year Award Winners


2009 Pipe Fabrication Project of the Year

A Hydroelectric Facility
This project used 1.2 Million pounds of steel and included a powerhouse, surge tower and switchyard and penstock.  The new powerhouse utilizes 80 percent of the annual river flow and produces enough energy to supply over 10,000 residential customers annually.  By contrast, the facility it replaced used just 20 percent of the river flow annually and the remainder collected in the spillway.
