Electrical Power for Valdez and the Copper River Basin-1981

Power Requirements Study (excerpt)Public BuildingsThis particular class of consumer consists of government offices, schools,churches, and other community type organizations. Since 1973 there has been asteady growth in the number of consumers. Continued growth is expected but ata slower rate experienced during prepipeline construction era. Averagemonthly consumption was projected on the basis that some consolidation wouldoccur within this class and larger facilities being constructed in the futurewhich could accommodate more than one type of activity.Large CommercialThe average annual kWh usage for this class has been estimated to show amoderate increase during the study period. Consumers ranged from 24 in 1974,39 in 1976 and 19 in 1978. The erratic growth is largely attributed topipeline activity and the subsequent completion of this project. In view ofthis, growth is expected to normalize and increase moderately to 21 consumersin 1983 and 24 in 1988. Both consumer and energy requirements were estimatedon a group basis.Over 350 kVAThe system is presently serving 4 loads in excess of 350 kVA, namely:1. Alyeska Mechanical Refrigeration No.2. Alyeska Mechanical Refrigeration No. 23. Alyeska Housing @ P.S. 124. Alyeska Pipeline Pump Station No. 12The Alyeska Pipeline Glennallen Camp has been completely phased out ofoperation. Alyeska Pipeline Pump Station No. 11 is expected to come on linebeginning 1983 as capacity in the pipeline is increased from the present 1.2million barrels a day to 1.6 million barrels a day. It is felt thatincreasing the capacity in the line must occur as the demand for oil in theContinental United States continues to increase or as oil exchange agreementsbetween foreign countries are eventually finalized. Therefore usage isexpected to be approximately equal to that of Pump Station No. 12.The refrigeration loads are necessary to freeze underground sections ofpipe to prevent melting of permafrost areas. These loads were projected onthe basis of existing usage.The pump station loads include all power to the station except for theactual pumping load. The pumps are run by customer self-generation.B-22
