First year kWh usage
I’ve been waiting patiently for our first year electric bill. We built a 28×38 3 car garage with a 2 bedroom ADU above it that we’ve been living in since last November. We have a Mitsubishi unit with ducts for upstairs and mini split heads for the garage. The building is pretty well insulated and pretty tight but there’s only so much you can do to garage doors. It is entirely electric with a HP DHW and HP Dryer. We have one hybrid car we plug in.
I’d like to hear opinions on our kWh usage. We do go to FLA a bit in the colder months. There’s 2 of us living here.

You'd need to seperate out your car's charging needs from those kwh numbers to be able to gauge the structure's performance. The car might be a BIG chunk (lots of driving) or a small chunk (just a little driving) of the totals, and the car's needs have nothing to do with the rest of the structure.
Do you have a way to seperate out the car's charging consumption from your numbers?

Not really. We plug it in every day but only drive a few hundred miles a week, if that. I can tell you we bought that car around April 2024, however.
Thanks for your input!
7700 kwh/yr seems very good to me. It's hard to gauge accurately because not many homes are built over a heated garage, and car-charging is another variable, but in my area (Maine), that would be about $1600, or $134/month, which is excellent in my book.
Thanks Michael. I didn't add up the cost, but Eversource is banging us pretty hard for Delivery and Public Works charges. This makes the kWh charge seem low while the bill is 1/3 kWh, 1/3 Delivery and 1/3 Public Works. Pretty tricky.
I understand; my electric company is consistently rated the worst for customer service in the US--even below Pacific Gas and Electric, which has caused huge fires and has frequent brown-outs.
Our total rate is around $0.23/kwh. I bet yours is no more than $0.30.
