Trust me. I can read my bill and do the math.

Not here, but even if so, so what?
Gasoline rates change in the northern hemisphere summer (go up) too.

Yes, and integrating, you get a bill, and do the math.
It's not rocket science.

For one month. Next month may have a different rate structure.>

So they do here. Which rate do you use to determine the cost of
electricity?

And next month, you have a different rate per kwh.

Right, the rate almos guaranteed to go up with energy supply cost.

My projection of the forward curve, rotating off the front month.
"High and higher."

No kidding, and no more of a case for a plug-in, around here at least.
As I say, at rates approaching $.20 per kWh, it's not rocket science.
No matter what sort of argument you want to make.

If the Toyota version of the Prius PHEV carries a 10K premium I couldn't
cost justify it even at my low off-peak rate.

Which is the price point of the aftermarket A123 battery system.
