The U.S. Department of Energy is seeking designs for hydroelectric turbines that are environmentally friendly, as a means of moving the its Advanced Hydropower Turbine System program to the next stage.IDAHO FALLS, Idaho, US, 2001-11-06 [SolarAccess.com] Expressions of interest close on December 6 for submissions in a program to stimulate the design, testing, field demonstration and deployment of a new generation of turbines that not only retain the life expectancy and efficiency of existing turbines, but have enhanced environmental performance. DOE wants turbines that have fewer effects on fish by resolving fish passage, water quality and stream flow issues in turbine design, and wants to demonstrate that a new generation of turbines can be compatible with environmental standards, be commercially viable, and successfully balance environmental, technical, operational and cost considerations. Bidders on this first solicitation must own rights to existing turbine designs and fund at least half of the development process. The turbine designs should be above 1 MW capacity, and address fish passage, water quality, instream flow and other environmental issues. The designs must be adaptable to new site development and for retrofits at existing sites. Applicants may be for-profit or not-for-profit organizations, state and local government entities, Indian tribes, and educational institutions. DOE’s Idaho Operations Office has developed two separate but related solicitations. The first (closing in December) is to select existing conceptual turbine designs to advance development to the final design stage, installation and testing. This will limit the designs from which proposers under the second phase can choose. All qualified hydropower turbine manufacturers that have existing conceptual designs ready for development and field-testing are eligible to compete in the first solicitation. The second solicitation will result in site selection, final engineering designs, installation of a full size prototype turbine, testing (both engineering and biological), O&M monitoring and generation. Site developers will be limited to the designs awarded under the first solicitation.
