We pay $0.81547 per 100 cubic feet. Let's say the generator runs at an average of 50% load. The 13KW generator uses 177 cu ft/hr or about $1.44/hr. $34.56/day. A month would be about 1036.8.
The electricity generated would be 4680 kW. Cost per kW would be around $0.22. Mind you, that is more than double our regular rate. But it wouldn't be $800/day.
Typically, I use around 100 kW/day. If I used a battery storage system for surge and for night time use, I should be able to get away with a 10kW unit and run full load during daylight hours.
My actual plan is to have a 50-70 panel solar energy system with 20 x 12V x 250 Ah batteries for night use. The generator would operate during the day and we'd work off batteries at night.
If instead I went with an 8kW unit, ran it 16 hours per day, with batteries for storage and surge, It would cost about $16/day and produce 3360 kW. My typical max summer usage is around 100 kWh/day. And I bet we'd trim our usage during an emergency (no AC upstairs, no use of the electric oven, etc.). Fuel cost would be $0.14/kWh.
