Got a response from Consumers Energy:
"There are many variables to consider when a new home has no history. Number of family members, insulation, orientation, type of heating and cooling, window U value and solar heat gain coefficient, shading coefficients, and so on. I can tell you that our residential flat rate is 12.25 cents per kilowatt hour with a service charge of $30.50/month for a 15kVa transformer placement. We also have a Time of Day program that sets your kWh at 7.6 cents for 22 hours with the peak from 5-7 p.m. at 37.7 cents. We also have a Heat Plus Rate that would entail an electric water heater to qualify and any heating or cooling of a conditioned space that uses some form of electric heat would be at 6.02 cent from October through May and 11.07 cents June through September. The added cost for the second meter is $5/month. Insulation is a big factor to consider when building new so you can reduce not only the size of the equipment but also reduce the energy usage on either gas, electric, or both. Please feel free to call and discuss further at your convenience. A word of caution, if you are considering floor heat below slab, make sure the contractor does not use a reflective bubble foil. He should use a minimum 2†extruded polystyrene and a vertical barrier at the footing 2’-4’ down. Thank you for contacting us!"
Looks like they have Time of Day Program that charges 7.6cents/kwhr for 22 hours in a day with the other 2 hours at 37.7 cents/kwhr. Seems pretty simple to disable your air conditioning for the time period 5-7PM to avoid these high charges.
Anybody have any recommendations on Electric/Gas for Electric water heater and how costs would be compared?
