Installation of Instream’s 25kW BAE Systems rotor and generation system in the Roza Canal, WA

On August 13th 2013, Instream Energy Systems deployed their newly designed 25kW BAE Systems rotor and generation system in the Roza Canal operated by the US Bureau of Reclamation (‘USBR’) near Yakima, Washington.

This installation initiates a comprehensive test program that continues at this site to today. Several Instream turbine systems have been deployed by installing canal spanning structures. The spans have been designed to prevent contact with the canal structure in order to preserve the physical integrity of the canal lining and not interfere with ongoing operations.

Project Objectives:
  • Demonstrate a secondary use for existing infrastructure;

  • Extrapolate energy potential to inform upcoming federal Requests for Proposals;

  • Showcase our technology to demonstrate no impact to the canal operations and the aquatic environment.

Having successfully completed Phase One of testing, Phase Two planning involving multiple turbines is presently underway. Instream has been working closely with the Bureau of Reclamation on this ongoing, long-term, hydrokinetic validation study.

Installing an Instream turbine 

The turbine is attached to a spanning structure that is secured to both sides of the canal on concrete foundations. The turbine is permanently attached to the structure.


To move the turbine out of the water the span is simply rotated into it's maintenance position.
