Per customer residential use was5,735 in 1979. Industrial consumption has grown rapidly in recent years,accounting for about 75 percent of total demand during the 19701s. Thecurrent commercial-industrial share of CVEAls generation is 74 percent(1979). The Alyeska Marine Terminal became electrically self-sufficient in1977. The impending ALPETCO plant will likewise generate its own powerutilizing waste steam. .The specific current power requirements of the community have beenclassified by CVEA as rural residential, small commercial, large commercial,and public buildings and street lights. An examination of each categorybecame the basis for a forecast by CVEA which was in turn adopted by APA andultimately by this study (with some modification). A detailed rationale forthe future needs of each of these categories is offered in the back of theappendix.B-5
