Our electric bill has been running pretty high even though it hasn’t been that cold and we’ve been supplementing with wood heat. Decided to track down the culprit and hooked up an energy usage monitor to one of our 5 sub panels. Gonna check the other 4 over the course of the next few days.
I had that too, after a few months they’d get around to it and it’s get a corrected bill. Really confused me the first time i noticed it.
