Intermittency Of Renewables?… Not So Much

32. I don't like the numbers

You are talking about a 'time of day' pricing structure that does not exist yet in most areas....so I don't have a firm basis of numbers to run. But, I'll assume the difference in wholesale vs retail in power where I'm at - 4 cents per kwh.

Using a 16 kwh Volt battery, which I believe can be completely discharged and recharged twice in one day, using the 14 kwh available for this. If I had my car plugged in all the time and never drove it, I would make $408.80 a year.

Since the warranty for these batteries is 8 years, I can assume that's about its serviceable life...8 years equals $3,270 in 'profit' from the power company. The batteries currently cost double that.

But I didn't need to run any numbers.

Seriously, ask yourself this question:

Why would the power company pay me more to use a battery than what it would cost them to buy their own battery?

The reality is that they won't. The only reason for a power company to use V2G is to pay a car owner LESS than what they would have to pay to own...which by definition means the car owner gets a raw deal.

I would neeeever do this. Now you believe its a 'no brainer'....so I assume you have run some numbers?
