Electrical Power for Valdez and the Copper River Basin-1981

Diesel costs came from historical data up throt,lgh 1979. TableVIII-4shows expenses for several years. Fuel costs per kWh generated haveaveraged almost 14 percen~ growth per year for the last 5 years; therefore,it is assumed to continue increasing'at something above the inflationrate. The study used 5 percent and 2 percent fuel cost escalation ratesas shown in TableVIII-4A.TableVIII-5 gives a summary comparison of Allison Creek and its alternatives.ThePRT undoubtedly does not include all costs. Nevertheless,it seems to be the most economical. The diesel comparison value isgiven for 1979 and estimated for 1980. Figure VIII-1 graphs theserelationships. .Average RatesTables VIII-6through VIII-9 indicate project payback rates for thedifferent alternatives. For comparison, continuation of diesel generationat 5 and 2 percent fuel escalation is shown in tables VIII-10 andVIII-lOA. The rates, summarized below, are not much different thanthose shown in Table VIII-S.45
