The contract between the United States and the Northern Colo- <br />rado Water Conservancy District specifies that the project shall be <br />operated primarily for irrigation, but provides that not less than 255,000 <br />acre;'feet shall be diverted through the tunnel in anyone year, distribut- <br />ed in whatever manner the Bureau of Reclamati on determines, for the pur- <br />pose of generating firm energy. The net amount of energy th!lt can be gen- <br />erated by the diversion of that quantity of water through the tunnel, <br />plus the average amount of power that can be generated by the Green Moun- <br />tain Powsr plant (No.5) and by Big Thompson water, less the energy re- <br />quired for pumping, is about 750,000,000 kilowatt-hours per annum. How- <br />ever, during the period of lowest water supply the project energy can be <br />firmed to 720,000,000 kilowatt-hours per annum by the use of off-peak <br />steam energy generated by existing steam plants (not including reserve <br />capacity) of the interconneoted Northern Colorado connected systems. <br />Tl'erefore. the provisions of the contract will not curtail the amount <br />of firm energy that can be generated. <br /> <br />6. It is estimated that 648,000.000 kilowatt-hours of firm ener- <br />gy per annum can be delivered at the market. assuming 10% loss in trens- <br />mission. In addition to the firm energy, 160,000.000 kilowatt-hours of <br />secondary energy will be available at the market. It is e"timated the <br />secondary energy can be sold at 1.8 mills per kilowatt-hour.. The cost <br />of the firm energy will be 3.47 mills per kilowatt-hours which includes <br />the cost of purchasing off-peak steam energy when necessary for firming <br />at 5 mills per kilowatt-hour., The above costs are on the assumption <br />all power wi 11 be absorbed when the proj eet is completed and goes into <br />operati on. <br /> <br />7. It is estimated that the project oan be essentially canpleted <br />by the end of the fiscal year 1944. The present rate of progress on the <br />construction of the Continental Divide Tunnel indicates that the exca- <br />vation wi 11 be cClll1pleted by the middle of the summer of 1943. Work on <br />other features of the project, however. must be vigorously pushed. in- <br />cluding the construction of Granby reservoir which is essential to the <br />production of firm energy by the projeot. <br /> <br />The following table shows the amount of the funds required to <br />canplete the power features of the project by the end of the fiscal year <br />1944.
