We just bought a 2200 sq ft home in March. BGE told us previous owner's average was $270-300something a month. Our most expensive was $204 during the summer rates when our A/C compressor wasn't working, so the A/C was running full time. This month's was $100. We have two fridges but a newer washer and dryer. Not sure about winter yet, obviously, but we have a oil furnace any way. I would say that as long as you don't leave every light and TV on all day, yours should be much cheaper than the renter's average.
Winter is when they get you. You have an oil furnace and shouldn't be posting in an all electric home thread.
Anyway, 1500 square foot, poorly insulated, baseboard heat home built in 1969 here.
We have SMECO.
Average for us is $300/month. The only advantage to baseboard heat is we can turn them off in rooms not being used.
We bought two oil filled portable radiators last month and will see if this will be better than the baseboard in the common living areas.
I had a heat pump prior to this home and the cost was about the same (same size house but much newer and better insulation) The company was Delmarva Power, and the rates were probably different.
Crazy when the electric bill is more than your monthly mortgage payment.
