Remote Alaskan Energy Applications Art Nash, Energy Specialist- UAF Cooperative Extension
Macro view- stranded resources Commercial energy resources with potentially large technical, logistical and locational challenges that have potential energy/economic value Often “Stranded” due to economies of scale, transportation limitations,or seasonality (solar, hydro, wind)
Alaska Peninsula and Aleutian Islands have at least 14 identified geothermal sites >302 ºF with possibility of 1,000 MW of electricity over 30 years.
The offshore wind potential along the Aleutian arc is tremendous; wind often augments diesel generation for Western Alaska remote grids .
Along the southern coast of Alaska and the Aleutians wave potential is ~200 times the State’s total annual energy needs.
Possibility of an increase in energy demand near stranded areas (by shipping and industry)
Energy Intensive Industries large base load renewable energy source proximity to global shipping routes presence of a deep water port supporting infrastructure requirements emphasis on energy export through value-added products, rather than transmission lines

Micro view- energy for remote camp, village or lodge • Demand-Howdo you use energy? • List the items currently that use energy at your camp/cabin • Estimate how many hours each is used and by which fuel/source • Figure out how much each uses – for generator figure out start up surge, estimate peak and continuous load Supply-What fuels do you have and use? What types of fuels do you currently use remotely? (white) gas, diesel fuel oil, propane, driftwood, cordwood What do you use it for? Cooking, drying or canning fish on the riverbank, laundry, sanitation, refrigeration, space heating, car, truck, boat, 4 wheeler, snow machine, lighting, communications, home electronics, CB radio What efficiency actions can you take to reduce need? bulb replacements, type of appliances, extending usage over the day to avoid concurrent load draws
Site and source considerations How windy is it, what times of day/year? How much velocity or volume are there in the rivers or streams nearby? How much direct & indirect sunlight is there? Where is the aspect usually? Are there hot springs nearby? Are there grasses, brush, trees or driftwood nearby?
