We have a 1344 sf house, oil furnace and boiler for hot water, electric stove, just my wife & I. Our November usage was 414 kWh. It's very hard to compare however. We have hot water baseboard so no forced hot air fans are running, just small water pumps for circulation. Our house walls are 6" and super insulated attic. The month before, our usage was over 500 kWh. August with a dehumidifier in the basement and a window A/C unit was 818 kWh. So 780 with a larger house seems a bit high for this time of year but it depends. Most of our lights are CFL or LED. If you have 6, 100 w incandescent bulbs running every night for 6 hours, that could add 110 kWh and $18 to your bill.
Power from NHEC is .09256 per kWh. With other add on usage charges, it's over 16 cents per kWh. Total bill was $97.
