So flat rate billing in Georgia?
Up here in Ontario Canada it's tiered to on-peak and off-peak, then there are delivery charges, regulatory charges, and then 13% tax on top of that.
My last bill was 6##.### something kW.hrs (we have 'smart meters' they measure to 4 decimal places) and was about $140 ish total which worked out to 21.82 cents/kW.hr!!!
And it's only going up!!
Like JAE linked, get one of those meters, and plug it into a pc for a week to get a good average for kw.hr used, then the repeat for the others, then multiply it through by your utility final cost.
