Remote Alaskan Energy Applications Art Nash, Energy Specialist-
UAF Cooperative Extension
Slide 2
Many remote communities with disconnected electrical grids
Slide 3
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)
Slide 4
Alaska Peninsula and Aleutian Islands have at least 14
identified geothermal sites >302 F with possibility of 1,000 MW
of electricity over 30 years.
Slide 5
The offshore wind potential along the Aleutian arc is
tremendous; wind often augments diesel generation for Western
Alaska remote grids.
Slide 6
Along the southern coast of Alaska and the Aleutians wave
potential is ~200 times the States total annual energy needs.
Slide 7
Offshore Cost Wells (Oil)
Slide 8
Coal
Slide 9
Possibility of an increase in energy demand near stranded areas
(by shipping and industry)
Slide 10
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

aluminum/day
Slide 12
Micro view- energy for remote camp, village or lodge
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
Demand-How do you use energy? 1.List the items currently that use
energy at your camp/cabin 2.Estimate how many hours each is used
and by which fuel/source 3.Figure out how much each uses for
generator figure out start up surge, estimate peak and continuous
load
Slide 13
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?

Slide 15
DC charge ( allows charging to peak without overcharging)
Slide 16
Battery backup considerations for Monitor, Toyo, Dewalt tools.
Pure sine wave inverters handle igniter start-up without ruining
your circuit boards on your equipment while modified wave inverters
may not.
