We live in la too, well the burbs. Now our power is only 40 bucks but we don't use heaters ever. During the summer it got up to 200 a month for our 1 bedroom apt with 4 people. Sometimes higher but our apt is old and the insulation is crap. We are on payment arraignments now to pay off some of the back. It is high out here and it depends on what you use and the efficiency of your place.
