Minimal additional infrastructure will be required to incorporate the turbine into this diversion <br /> dam. A general schematic of the proposed configuration is shown below. This schematic does not <br /> reflect the entire site, but only the bay that the turbine will be installed in. As you can see in the <br /> photograph of the site, there are two bays with radial <br /> gates (sand gates), one of which will be used to house the <br /> turbine. The radial gate will stay in place and the turbine <br /> ,...,....S., will sit behind a new concrete wall within the bay. The <br /> ��•. .�,_/ draft tube will extend into a lower stilling pool that will <br /> . ./ `''`- maintain adequate submergence. <br /> The Ogee Weir of the diversion dam will act as a bypass in <br /> 'i� the case of emergency or maintenance. The radial gate <br /> will be programmed to close in the case of a grid failure to <br /> Schematic of proposed configuration prevent run away speeds in the generator.A simple crane <br /> will be installed above the turbine to assist in the removal <br /> of the cassette for maintenance. <br /> Upstream of the turbine a screen will be installed to prevent the passage of large fish into the <br /> machine. The SLH turbine will pass smaller 2-4 inch long fish without damage to the fish or the <br /> equipment. Larger fish will not be allowed to enter the machine using the screen. This screen will <br /> be designed to be self cleaning and require little maintenance. <br /> CONCEPTUAL PLAN <br /> Conceptual plans including a plan and elevation of the hydropower facility is included in Appendix <br /> B of this report. <br /> COST ESTIMATE <br /> Engineers Opinion of Probable Construction Cost <br /> rApplegate <br /> Group... <br /> 1499 W 120th Ave. Job No.: 11-108 <br /> Suite200 Low Head Hydropower Installation By: LAG <br /> Denser,CO 80234 Date: 6/3/2011 <br /> Phone:(303)452-6611 Cient Rio Grande Canal <br /> Fax (303)452-2759 <br /> Description of Work Item Units Quantity Unit Cost Total Cost <br /> Turbine,Generator,electrical equipment and draft tube EA 1 $ 250,000 $ 250,000 <br /> Installation of turbine EA 1 $ 10,000 $ 10,000 <br /> Modification of sand gate EA 1 $ 92,000 $ 92,000 <br /> Cassette Crane EA 1 $ 3,000 $ 3,000 <br /> Skiing Pool EA 1 $ 30,000 $ 30,000 <br /> Cofferdam during construction EA 1 $ 10,000 $ 10,000 <br /> Screen upstream of unit EA 1 $ 15,000 $ 15,000 <br /> Natel Hydroengine Extension of transmission line and transformer EA 1 $ 30,000 $ 30,000 <br /> Installation Interconnection EA 1 $ 10,000 $ 10,000 <br /> $ 450,000 <br /> Engineering and construction management $ 30,000 <br /> FERC Permitting through GEO Pilot Project $ 15,000 <br /> NEPA Compliance $ 10,000 <br /> Contingencies $ 46,000 <br /> Total $ 551,000 <br /> Rio Grande Canal Water Users Association I Project Description 6 <br />
