Yep, exactly. At our previous place we never had an outage last more than a couple hours, in 7 years, so it didn't make sense. Current place has had four in the span of four years, plus we have geothermal heat so we can't just hook the furnace to a portable genset. It'll never pencil out in terms of dollars saved on lost food and hotels, but just knowing that the power will be out for a max of 15-20 seconds makes it worth it for us.
