<br /> <br />~s <br /> <br />. <br /> <br />. <br /> <br />~ <br /> <br />'~ <br /> <br />Contractor will use an appropriate computer program in <br />consultation with the CWCB. The streamflow sequence <br />used to develop the reservoir design will be used for <br />this analysis. <br /> <br />To perform the above-~entioned reservoir system <br />analysis to optimize power generation, the outlet <br />sizes, turbine capacities, reservoir operating rules <br />and allocation of reservoir capacities for alternative <br />purposes will be esti~ated. These parameters will be <br />suitably modified as the various elements of the <br />reservoir design are tinalized in consultation with the <br />CWCB. <br /> <br />The cost of procurement and installation of the <br />hydrogeneration equipment will be based on quotations <br />from manufacturers. the cost of distribution and price <br />of electric power will be estimated using information <br />obtained from the Public Service Company of Colorado, <br />the Western Area Power Administration, and the <br />Tri-State Generating and Transmission Association as <br />appropriate to the analysis. <br /> <br />For the selected hydropower system, the Contractor <br />will develop conceptual plans for the various <br />structural, hydraulic, mechanical and electrical com- <br />ponents. These plans will be used for quantity <br />takeoffs and developing associated appraisal level cost <br />estimates. <br /> <br />In considering pumped storage, the potential for <br />raising the ring dike, if needed, to increase the <br />storage capacity for the Riverside Reservoir will also <br />be investigated. The purpose of this alternative would <br />be to create supplemental storage capacity that could <br />be used at the lower reservoir for a low-head pumped- <br />storage scheme. <br /> <br />d. prospective recreational uses of the reservoir will be <br />included in the development of storage scenarios. In <br />particular, the value of the reservoir for water craft <br />(power and sail) recreation, warm-water fishing and <br />waterfowl hunting will be investigated. <br /> <br />The annual reservoir f1uctuation will be studied in <br />terms of specific 1eve~ of maintenance, timing of level <br />changes, and rate of level changes as may impact <br />prospective recreation utilization and level of usage <br />(visitor-days). This issue is particularly important <br />if the pumped storage concept is found to be feasible, <br />due to water fluctuations associated with alternative <br />pumping/generating cycles. This information will be <br />used in the economic e~a1uation of recreation benefits. <br /> <br />-9- <br />
