But can your generator power the fuel pumps down the road
when the main grid is down? How about highway maintenance & all other associated costs with energy, vehicular depreciation, replacement, etc?

Disposable portable generators are OK for a few weeks a year. Any heavy lifting (well pump, water heater, freezer, appliances, furnace, et al) and you're waiting for a miracle. Batteries wear out, even deep cycle marines.

Such also is the life of a survivalist or rugged individualist, whose reliance on manufactured goods, services. Some, more paranoid than others; a few must also own stocks in ammo & firearm manufacturing. They attend 
routinely to drive up their value along with costs of ownership.

A larger concern with the power grid in Alaska, would be once it is bigger
and contains all regions under one consolidation, is that it may be sold or run like a for-profit where they lobby for no restrictions and no caps. Unified, it may cost everyone more; with less regulatory over-sight.
