First, turn off everything in the house for as long as you can stand it and make sure the meter does not advance.
If you pay 16 cents/kwh and your meter is off 1% in their favor and you use 1kw all the time they owe you $14/yr, plus interest.
You'd need a meter 5x or 10x more accurate than PoCo's meter, and I can't readily find a published spec. for this number.
If you can find a stable 10A load, like a toaster, you could measure the volts and amps going into it, probably to 0.1%. A 100A, 240v load would be better, like the aux heat coils for a heat pump. Everything else should be off.
To get high accuracy, measure and record the values until you get bored. Volts x amps x time = watt-hours. 240v on average at 100A on average for 0.1 hour = 2.4 kwh.
If you find credible evidence for "an error" in their favor and make a fuss, they'll be watching you! Along these lines, the Gas Company [GaCo?] tried to entrap me after I called them on their bad behavior, on behalf of a customer of mine.

BTW, if it really is an "error" half the time in the long run it would be in favor of the consumer. I doubt that this will be the case. By this standard, politicians almost never make an error, regardless of them calling it a "mistake" or that they "mispoke."
