Virginia, North Carolina: Are you aware of the Dominion Power EV Pilot?

[Bifff67]

Dominion power has a pilot program to study the effect of the Electric vehicle on the power grid. The program is just for a couple of years and has a limited number of customers. They have two programs that provide variable rates, one that gives you a separate EV meter, and one that gives you a whole house meter. I am on the whole house meter. I would like to know of other people in the program and hear any comments. For me, I have the Roadster set to charge at 1AM when the rate drops to 6 cents per kWh. The EPA rated the Roadster at 119 MPGe using 12cents per kWh. On this program, I am getting better than 200 MPGe!

I think MPGe is a measure for energy consumption, not for price. 119MPG (equivalent) means, you use 34 kWh per 119 miles, where 34kWh is the energy equivalent of one gallon of gas.
Besides that, 6ct/kWh is a bargain, giving you 1.7 cent per mile versus ~50c/mile in a comparable ICE.

Damn I'm spoiled. Georgia Power rates for Atlanta. I will probably end up monitoring my power usage through a summer on the normal rates before I figure out how much on peak power I will use. Not sure it will be worth the super cheap night rates, other than to brag that it only cost me $0.50 to fill up my car.

EV plan give you 1.25ct/kWh for 8 hours at night. The 19ct/kWh during day is rough.

But the regular plan is only 8.6ct/kWh peak cost in the summer.

I"m considering doing this if it is still open. But as I understand it, your summer daytime rates go up with this program, right? If so, I'm concerned that the extra expense on A/C in the summer may outweigh the savings on the Model S, since it will be our only EV car for now.

Yeah that is the way it is in Georgia. But what you can do is when you want to replace your Model S battery, use your old to power your house during peak, and charge it up at the lesser rate! Makes swapping your battery seem like a good thing.

Thanks for the replies.

Evin, there are two plans. One is a whole house meter and then you would want to manage all of your usage like you said. But they also have a meter for the EV only. Problem with that is the need to do special wiring, but then you could get the cheap energy just for the car. Its never easy. See all the links in original post.
