Abstract: The Idaho Falls Low-Head Hydroelectric Demonstration Project consists of the redevelopment of three existing power plants using identical bulb turbines and generators. This paper summarizes the construction of the project, installation of the turbines and generators, and covers the start-up and testing of the generating units. Each unit is rated 8000 MW, 4. 16 kV with a flow rate of 6000 cfs, at a head of 18 feet and a speed of 94. 7 rpm. The project was completed for a cost per installed kW of 2282. Start-up and testing of the generating units and auxiliary systems included mechanical and electrical equipment checks, mechanical runs, load rejection, power system stability and index tests. The units were placed into commercial operation within 59 to 92 days of the original contract dates.
