The Plug-In Toyota Prius is coming in 2010.

What's the relationship cost per kWh power : cost per mile driven?

I calculated the gas/electric equivalency at my off-peak rate a few years
ago when the first plug-in Prius modifications became available.  At my
rate, which has since seen a slight increase, it was equivalent to 70
cent/gallon gas.  Since my electricity comes from coal I expect the cost to
increase dramatically over the next couple of years but even if it doubles
it will be equivalent to $.40/gallon gas.  My present off-peak rate is
.043/kwh.  My electric co-op says they will "work with me" on configuring my
off-peak system to accommodate a plug-in vehicle since there aren't any on
their network now.

The maximum all-electric range at the time I looked into this was 40 miles
but I'd guess a practical range would be closer to 30 miles.  There wouldn't
be a big advantage to a traveling salesperson who drives 200 miles a day
since there wouldn't be an opportunity to recharge.  Someone with a 30 mile
or less round trip commute would save a bundle at my current off-peak rate
since they could recharge regularily.

Our 24 hour rate (no off-peak metering) is $.198 per kWh (and going up
with NatGas), so sounds as if this translates to $.50/gallon (and going
up).  Not so compelling here.

I don't believe it is possible to calculate the cost of electricity. The
rates change in summer, to start with.  Furthermore, there is a fixed
charge for connection, and the rates depend on how many kwh are consumed
each month (so much for the first 800 kwh, a different rate for the
excess).  I don't see any peak/off peak rates, other than seasonal.

How many kwh will it take to recharge a 2010 Prius which has been driven
200 miles?  It may have used 3 to 5 gallons of gas in that same time.
