The city of Fairbanks has a population closer to 40,000. The surrounding small towns and military installations almost double that, but I don't they're included in the backup plan. I think the batteries are supposed to provide power to 12,000 hourseholds, rather than individuals. In the slightly more than 2 years that I've lived here in Fairbanks, I've noticed that the town is plagued by frequent brief interruptions in the power. Just enough to get all the clocks in the house blinking. The TV ads promoting this new battery backup building have emphasized that the blinking clock scourge will be coming to an end. And if the power does stay off for more than that 7 minutes, I'm ready with my kerosene heaters to keep my house and pipes above freezing temps.
