$0.17 USD for the first 273 kwh, $0.25 per kwh over that, up to 1000 kwh, then $0.35 per kwh over that. with 4 people in the house and 2 tents we usually end the month in the middle of tier 2 electricity usage. ($200-300) but we've gotten to tier 3 before ($450-$500 with the help of the lasko heater). this is why i dont drive a tesla.
another problem i have with that heater is it runs at 6A/12A and i have all my stuff plugged into one outlet
