The maintenance is also lower or is that going to get cheeper as time goes by. Lines would be a great thing if you owned the chopper company that does all the expensive work. Driving C-Train on a winter only road for 3 months and then everything is parked during the time the swamp and tundra are un-thawed. You can't drive around to do ant servicing. Add the expense of fixing that is something that can't be done yet because ways to fix the erosion that results is something that is a work in progress. Lines can't be cjeaper at any break even point when servicing the 'far north'. Power is certainly the answer as far as fences go, after that it is a very many square miles per person. You want reliable power for a winter with extreme weather but also providing enough that the people are not hole up because resourses are low because the 'south' is taking more power than predicted or some other calamity that is beyond the ability of the people in the far north to 'fix'.
