ECONOMIC SENSITIVITY STUDIES PERFORMED AT THE REQUEST OF CORDOVA ELECTRIC COOPERATIVE DISCUSSION AND RESULTS The economic evaluations included in this section represent a sensitivity study regarding the effect of discount rate variations on Cordova power supply alternatives. This economic sensitivity evaluation was made at the request of Mr. W. OD. Bechtel, General Manager, Cordova Electric Cooperative. The study was performed on the following cases: is Silver Lake Hydroelectric Project (15 Mw) Zs Silver Lake Hydroelectric Project (15 Mw) with the sale of excess power to CVEA 35 Modification of the existing diesel plant at Eyak Lake (Case DO1) 4, Optimized coal plant near Fleming Spit (Case CO3E) 5. Purchased power at Teeland The above cases are typical of the power supply alternatives described in Volume 1. This sensitivity study was performed to illustrate the effect of different discount rates on the relative economic performance of the ‘five alternatives. This study is of interest since, depending on the degree to which the State of Alaska funds a power supply system for Cordova, significant variations in the discount rate could occur. In Section 9 of the report, economic evaluations were performed in accordance with Power Authority Guidelines. However, for this evaluation only, the following economic parameters were used: Inflation Rate 7 percent per year (through 2002) Petroleum Fuel Escalation Rate 9.6 percent per year (through 2002) Discount Rate 0, 10, and i5 percent per year Analysis Period 1982 through 2035 By including inflation and variations in the discount rate, their effect on the relative economic performance of capitai intensive projects (such as hydroelectric) compared to fuel and Operation and Maintenance dominated projects (such as diesel or coal plants) can be illustrated. The results of the discount rate sensitivity study are shown in Table 1. For both 0 and 10 percent discount rates, Silver Lake with the sale of excess power to CVEA has the lowest present worth cost, followed by Silver Lake without the sale of excess power. Therefore, for discount rates up to 10 percent, Silver Lake is the economically preferred option for supplyia power to Cordova. However, the relative performance of the alternatives changes when the discount rate is between 13 and 15 percent. In this case, the preferred option is DO1, modification of the existing diesel generation plant at Eyak Lake. Silver Lake with the sale of excess power to CVEA, the second most cost-effective alternative, is 14 percent more costly on a present worth life-cycle basis than DO01. The other three alternatives, including Silver Lake supplying Cordova only, CO3E, and purchased power, are from 34 to 44 percent more costly than DO1. a This change in the relative performance of Silver Lake compared to DO1 results from differences in the timing of capital and O&M costs between the two cases combined with a high discount rate (15 percent). In case DO1, the near-term capital cost is low, but high fuel and O&M costs escalate rapidly in later years. In comparison, the Silver Lake option has high near-term capital costs, with no fuel and low O&M costs in later years. The high discount rate tends to minimize the importance of costs in later years (such as 20 years in the future and beyond). Thus, the high near-term capital cost of Silver Lake becomes dominating, while the high fuel and O&M costs for DOl which occur in future years become less significant. The result is a higher present worth cost for Silver Lake, with or without the sale of excess power, compared to case DOl. Therefore, as described in Sections 9 and 10 of this report, Silver Lake is clearly the preferred option for supplying power to Cordova under the economic parameters specified by the Alaska Power Authority. However, the relative economic performance of the power supply alternatives will change with significant variations in economic parameters. As shown in Table l, diesel generation at Eyak Lake (D01) becomes the preferred option at a 15 percent discount rate. Variations in other economic parameters, such as petroleum fuel escalation rate, would also have a significant effect on the relative economic performance of the alternatives.
