• Renewable Power in Rural Alaska: Improved Opportunities for Economic Deployment

      Crimp, Peter; Colt, Steve; Foster, Mark (2007)
      Sharp increases in the price of distillate fuel have led to wider economic opportunities for local renewable energy resources in the over 180 rural Alaskan communities that are served by electrical microgrids isolated from larger population centers. Between 2002 and 2007 the median price of diesel fuel for utility power generation in rural Alaska increased by 72% to $0.71/l ($2.70/gal). During this period the median unsubsidized residential cost of power increased by 20% to $0.468/kWh. The Alaska Rural Energy Plan, based on 2002 fuel costs, indicated widespread opportunities for cost-saving measures from end use efficiency, diesel generation efficiency, diesel combined heat and power, and wind energy. This paper assesses economics of small hydroelectric, wind-diesel, and biomass-fired combined heat and power under a range of future oil price assumptions.
