�1 � Results of a peaking power study which was recently (January 1989) icompleted for the Authority indicate that a total installed peaking capacity of 450 MW (medium growth) to 825 MW (high growth) may be economically Iattractive within the State of Colorado by the year 2007, if the cost of that capacity is in the range of 51000/kW to 51200/kW. It appears, therefore, that � both of the pumped-storage projects evaluated in this study may be financially feasible and could possibly serve as a method for enhancing the financial attractiveness of an in-basin water resource development plan, provided that -{ the economic benefits of the project are shared in an equitable manner between the water supply function and the power supply function of a combined project. 8.3 OUT-OF-BASIN WATER SALES 8.3.1 Introduction lThe possibility of exporting water from the study area to the Front Range was investigated as a potential method of enhancing the financial feasibility Iof an in-basin development plan. The purpase of the investigation was to determine if the potential for an export project exists; and if so, to make a Ipreliminary determination as to whether such a project appears to be financially feasible and therefore would warrant further, more detailed siudy. I Water sales to downstream states was not investigated due to institutional constraints associated with such an arrangement. + A review of existing data and reports identified three previously studied projects which would divert water from the Upper Taylor River basin to either � the Arkansas River basin or the South Platte River basin. These �rojects are: o the Collegiate Range Project as proposed by the City of Aurora; o the Union Park Water Supply Project as proposed by Arapahoe County; and o the Central Colorado Project as evaluated by the Central Colorada Water Conservancy District. 8-3
