I just looked at our December bill and it's 712 KWH compared to 530 a year ago and 401 for November for $238.21 in charges. We installed an electric water heater in late November so that may have contributed to higher usage. This is for a 1,200 sq ft townhouse. I think that the highest electric bill we've ever had is around $300 but that was many years ago.

Power costs is $0.22566 per KWH for $160.67 and about $0.09 in delivery charges or about $0.32/KWH.
