Presuming no carry over charges from the previous month or "equal
billing" plans, the cost per kWh is the total bill divided by the number
of kWh listed for the billing period. It makes absolutely no difference
what parts are attributable to generation, transmission, taxes, etc.,
the total bill divided by kWh is the amount you paid per kWh. Also, do
the math yourself, as the "cost per kWh" listed on some utility bills is
fraudulently calculated, excluding taxes and fees.

I would like to modify this a little:

The total per KWH cost is determined like this:

1. Subtract from the total bill the amount not related to KWH, in the
likely event you have that. This would be a monthly line charge, monthly
billing charge, or the like.

Doing this leaves the generation cost, transmission cost, distribution
cost, fuel cost adjustment, energy optimization cost, male fertile bovine
digestive product cost, and the taxes that should at least mostly be on
these. These would be on a per-KWH basis.

(Should you find or determine a tax or surcharge or portion thereof that
is on the monthly flat fee as opposed to the per-KWH related charges,
subtract that along with the monthly flat fee. But if you fail to do
that, you should not be off by much.)

2. Divide the result of Step 1 by KWH consumed. That is your actual
per-KWH cost.

(You will be off, very likely only very slightly, if you fail in Step 1
to account for any surcharges/taxes on non-per-KWH charges.)

No, you have to include every single charge on the bill as it is a
component of the cost you paid per kWh during that billing period.
Whether some portions are fixed charges that don't vary with kWh used is
not relevant, they are still part of the cost you paid for each and
every kWh you used that billing period.

That is a cost that does not get reduced by reducing electricity
consumption.

Going by what you advise, reducing electricity consumption of some loads
increases the cost of unchanged loads.
