A lot of areas have tiered rates. The "base" tier might be <$0.10/kWh, 
and the average might be in the $0.10-0.15 range (most of the US is in 
that range).

However, in this application, you should be looking at the marginal 
rate.. what does the "next" kWh cost, and in a tiered environment that 
can be pretty pricey (0.34/kWh for me in Southern California, last 
month, because it was hot).

Throw in time of use metering and it gets more complex. (and worth it to 
charge a battery at night and disconnect from the line during the day).
