In northern Illinois where I live, electricity is provided by ComEd.
However ComEd is really two companies. One delivers electricity and
the other generates electricity. In my last bill, that portion that
was billed for "Electricity Supply Services" accounted for only 55
percent of the total bill. As the guy who writes the checks, the
simple formula I use is Total Cost / kWh. This comes out to $0.149 per
kWh. On the bill the stated cost of a kWh is only $0.06968.

Our rates change with the seasons, summer tacks on extra as you go
over some set amount, then there is a winter rate that remains fixed and
spring and fall rates. Soon we are to get smart meters then there will
be extra charges during peak use hours in the summer. Some day I'm
going to get around to putting the kil-a-watt on the big screen and try
to determine what that thing actually costs to run 24/7.
