Someone who complains about a few hundred bucks for a few days outage needs to consider the cost of moving out for a while, losing their salt water aquariums, etc.
Just one large freezer will hold a lot more than a few hundred dollars of meat or fish.
Electricity is something that is easy to take for granted.
Shaking my head over ur's tenant "demanding" a generator. No utility will legally commit to 100% uptime; why would a landlord ?
If someone can swing the cost of a whole house generator, they can afford to fuel it. That said, my personal preference is a hybrid approach -> batteries+inverters+generators..... for efficiency - what 90cummins is working with, for example.
CBC news had a clip a few Winter's back, about a guy from Up North visiting inlaws in the heart of old Toronto at Xmas time. Extended power-outage hit, so he went out and bought a Honda suitcase gen and circulated it between his inlaw's house and several neighbour's places. He wired in pigtails to temporarily get each house's natgas furnaces to run - warmed up a house, moved to next one...... repeated as needed. Any "city" person could have done the same, all that was needed was a bit of money, some basic skills, and most importantly, initiative.... lacking that, in a city there may be other services/resources to bail you out.
Out in the middle of nowhere ? Don't go there, IMO, if you don't have a self-sufficient mindset....
Bad ice-storm at the moment in the Fraser Valley BC, lots of people w/o power yesterday and today.....
