It's more fair, let the family go right up to the edge of what they can pay, and when everything is 'solved' deactivation costs next to nothing compared to removal.
But I just realized, that since I have gas heat (but an electric stove), the heating isn't included in this report. Not sure what the averages would look like if I had a heat pump, but I'm assuming it would be similar to the A/C peak in the summer which adds about .5 to 1 kWh.
HN already determined washer/dryers are out. Assuming you cook for 20 to 30 minutes, how much instantaneous load does this add?
* furnace blower: 400W
* fridge: 300W
* microwave: 1000W
* toaster oven: 1200W
* slow cooker: "70-150 watts on LOW and 150-250 on HIGH"
* hot plate: 1500W
With these in mind, it's not hard to imagine how you can hit the 1800W limit when you're cooking. If you get unlucky and the furnace and fridge both decide to turn on at the same time, you only have 1100W available for other stuff. It's definitely very limiting, but at the same time it's also not something that would prevent you from cooking a healthy/cheap meal (eg. running a rice cooker + slow cooker)
