FDE "Family Dwelling Efficient" A plan for energy efficient homes

.030009/kWh all other times
I am on the FD plan and interestingly enough, I can never get my calculations anywhere close to what my bill shows. As an example; for this month my bill shows 1254 kWh consumed and a charge for the FD plan of $128.57 (before taxes). Using their rate plan, my calculations come to $90.77. This holds true for every month that I check. I've yet to get a reasonable explanation as to why this is.
Using this month as an example again here's my numbers:
1254 kWh consumed
FD plan for this period: .070099/kWh for the first 750kwh and .058099/kWh for usage over 750 kWh
1254kWh - 750 kWh = 504kWh used over "split"
750kWh * 0.070099 = $52.58 <-- charge for usage under 750kWh
504kWh * 0.058099 = $29.29 <-- charge for usage over 750kWh
Base Charge = $08.91 <-- The Base Charge
When added together, that comes to $90.77, much less than the $128.57 that's on my bill. I've sat on hold numerous times waiting for somebody to explain this to me, but have yet to even hear an attempt at an explanation...
