I'm not smart enough to know! I got the rate from the website; I guess I'd have to look at the bill to see if there's anything on top of that. If there are any fixed fees I guess that's sort of irrelevant, but I honestly don't know if there's another variable piece on top of the 7.53.
Basically, divide your total bill by the number of KWH used—that’s your true cost per KWH. The 7 to 9 cents per hour that everyone quotes is misleading since it doesn’t reflect the cost of being hooked up and supplied by the grid. I have solar but still pay a monthly fee imposed for being connected to our utility plus the distribution fees associated with my acquisition of electrons above and beyond what my panels produce.
