New Turbine Technology Tested by Associated Press Idaho Mountain Express - July 24, 2002

IDAHO FALLS -- Three hydropower producers have been selected by the U.S. Department of Energy to advance the development of fish-friendly, more economical hydroelectric turbine systems.

AmerenUE of Eldon, Mo., will test the Retrofit aeration System on Missouri's Lakes of the Ozarks. the system is designed to increase the amount of dissolved oxygen coming out of hydro turbines.

At the Wanapum Dam on the Columbia River, Washington's Grant County Public Utility District will test a fish friendly Kaplan turbine. The system allows salmon smolts to pass through the turbine without injury.

Public Utility District One of Washington's Pend Oreille County will test other devices designed for two-way fish passage.

Participants selected new turbine technologies best suited for their sites. The units will be monitored over the next two to five years for fish passage safety, water quality and instream flow.
