You have to use heavy power rationing if you are on UPS. Devices on heating line are automatically out- Water heaters, refrigerator, microwave ovens etc. The lights run on CFL's whose power consumption is really low. I very rarely use TV during power cuts, unless I'm sure the power is sure to return in 2-3 hours.
The rest wifi modem, laptop etc are all lower power consumption devices.
