Load FactorsThe following chart lists historical load factors, showing the relationshipbetween e.nergy and peak demand in percent:Valdez Glennallen Total CVEA1970 58.2 53.1 55.8.1971 57.4 57.8 57.51972 55.7 56.6. 56.11973 57.7 57.3 57.51974 . 43.7 52.5 46.81975 43.9 41.8 43.21976 60.9 43.3 53.61977 61.3 57.0 59.31978 56.3 58.3 57.21979 62~3 60.9 61.6Avg. 55.7 53.8 54.9Load factor equals energy divided by the product of peak demand andhours (8,760 hours annually). A peak load and subsequent installedcapacity forecast can be obtained from the energy forecast by using anaverage assumed load factor. The load factors are fairly constant except.during the years of greatest pipeline activity. Revised averages obtainedby excluding those years are:Valdez58.7% (1974-1975 excl~)Glennallen 56.7% (1975-1976 excl.)Total CVEA 57.3% (1974-1975 excl.)RatesRates to residential customers as stated in the Alaska Public UtilitiesCommission (APUC) annual report of 1979 were as follows (in C/kWh):For.
