FUTURE NEEDSThere have been three recent projections concerning electricity demand inthe Valdez-Glennallen service area. The earliest was produced by the AlaskaPower Administration and subsequently appeared in a March 1979 report entitledUpper Susitna River Project Power Market Analysis. This report considers theCopper Valley utility district for intertie with the proposed Susitnahydrelectric project. The forecast provided by APA was made during a periodof unprecedented growth in the study area. Consequently it is the highest ofthe three load forecasts, as will be illustrated. The second projection(chronologically) appears in the Power Cost Study 1979-1993 prepared for CVEAby Robert W. Retherford Associates, also in March of 1979. Contrary to theAPA forecast, this projection was formed during the post-pipeline wind-downand reflects the reduced expectations of that period. Like the APA analysis,it does not take into account the recently initiated ALPETCO refinery. Thethird and most recent load forecast was also conducted by APA, and appears intheir marketability analysis provided for this report. The relative positionof APA's 1980 projection can be seen in the following comparative tables:Table 3VALDEZ-GLENNALLEN AREA UTILITY FORECASTSUpper Susitna Project Power Market AnalysisEnergy (gwh)Peak Demand(MW)CVEA lLCVEA lLYear Glenna1len Valdez Total Glennallen1976 12.5 24.5 37.0 39.3 2/ 3. 11977 21.0 27.0 48.0 47.4 2/ 4.21978 22. 1 27.2 49.3 43.8 2/ 4.41979 24.0 27.6 51.6 41.6 ]j 4.61980 45.9 27.9 73.8 7.31981 48.5 30.5 79.0 7.71982 50.0 33.0 83.0 8. 11983 52.2 35.5 87.7 8.51984 55.0 38.2 93.2 9.01985 57.6 41.4 99.0 9.51986 60.0 45.0 105.0 10. 11987 63. 1 48.5 111. 6 10.61988 66.0 52.5 118.5 11. 11989 69. 1 56.8 125.9 11.71990 72.3 61.4 133.7 12.41991 75.0 66.4 141.4 13.0Valdez6.05.95.85.85.86.36.87.48.08.69.310. 110.911.812.813.81995 1802000 2402025 1,0251/ Copper Valley Electric Association Forecast from 1976 REA PowerRequirements Study.2/ Historical valuesB-8
