Box 7002Anchorage, AK 99510Dear Colonel Nunn:This is Alaska Power Administration's power market report for theValdez-Glennallen area.The power market analysis includes load projections, power market sizeand characteristics, a review of available alternatives, and a determinationof marketability and financial feasibility. APA consideredvarious alternative power supply alternatives as follow-on projectsafter completion of the Solomon Gulch Project. They were:1. Allison Creek.2. Pressure reducing turbines (PRT's) in the Alyeska Pipeline.3. Interconnection of CVEA system with Railbelt power supplies.4. Use of diesel generation.The marketability findings were:1. PRT' s appeared to have a tremendous cost advantage over otheralternatives.2. If PRT's are constructed, Allison Creek could be deferred afew years. If not, Allison Creek would be needed as soon aspossible after completion of Solomon Gulch.3. Allison Creek represents generally a higher cost of powercompared to other projects now under active consideration inthe State.4. Railbelt power supplies made available through interconnectioncould be competitive with Allison Creek.
