Hmmm...Mr. Wood references a 2014 article on the economic feasibility of this  but doesn't post a link too it. Here it is:

It says a power plant designed for the Arctic, converter stations in Fairbanks and Anchorage, and an 860-mile high-voltage DC power line would cost just under $4 billion and could deliver electricity from the North Slope to the Railbelt for 9.3 cents a kilowatt hour. 

The price to remote Alaska villages would likely be much higher. 

This idea would likely increase the cost of electricity to residents of Anchorage, Mat-Su and the Kenai Peninsula Borough, who use natural gas for heating and electrical generation.
