It's not unusual for average people to have electric bills upwards of 2-3 hundred dollars depending on their household setup. For instance, if a family uses electric heat they burn between 700 and 1500 watts on average per unit! During the summer they can use a lot of electric with A/C's and fans. I've heard of average families having $350 electric bills. If the electric company were to raise suspicion on every case like this they'd exhaust way too many resources, and probably never find anything important. You have to remember that your electric company is an institution which makes money off of its' clients so they are content usually as long as you pay your bill, and don't attempt to steal electriciy. The only case where you could get busted is if the police become suspicious of your "activites" and start an investigation, in which case they could pull your records.
