I just got my electric bill and it's $155 (small 2 bd apt w baseboard heat) for December. I'm really hoping they estimated it b/c it's never been that high before, ever and we've been here for 6 years.
Go look at the numbers on your meter if you can. My parents got a $2000 bill once. The person checking meters inverted two numbers. It was a big fight but they got the bill corrected.
