Right, I was objecting to the P.P.S. "tidbit" ... the energy circulating around until ... is a misconception.
WWBD said:Between 10 p.m. and 6 a.m., excess energy may be wasted on the grid network because it has nowhere to go other than to continue traveling around the grid transmission line infrastructure, gradually becoming dissipated in the form of heat.
The electricity grid is a dynamic entity in a constant state of flux as the levels of supply from generators and demand from all consumers constantly change. Electricity cannot yet be stored economically: excess supply one day cannot be used to meet a surge in demand on another day. So the grid’s operators must ensure that the amount of available electricity matches the amount consumed at any time, and vice versa. The grid must be able to respond to predictable movements in demand patterns as well as random, second-by-second changes. The grid’s operators must also have plans in place to manage a major interruption to supply, such as a power station failing. To keep the grid balanced, traditional generators have a throttle control that enables them to vary their output instantaneously – this is known as response. The grid also maintains a buffer of spare capacity from ‘balancing stations’ which can be called on at extremely short notice. If a power station goes down, or there is a problem in transmission, these ‘spare’ stations swing into action. The problem the grid operators have is that this insurance policy is expensive. It adds to the cost of power supply and, because it must be kept running at a low level at all times, it produces CO2 emissions even when power is not being used.

I've heard that electrically, an EV that is heavily used appears to the electric company as a new small house. So yes, the electric companies have some work to do....but these cars will slowly come on-line, so they can work as the demand builds. But if the electric companies don't look ahead, they'll get caught with their pants down and then blame everyone BUT themselves!!

But those of us that will be charging with our pvs during the off-peak day hours (as I plan to do) should help some, and more and more people will be getting pvs before the rebates and tax credits run out or change.
Jimmydreams said:I've read that something like 73% of todays commuting traffic could switch to electric and our national grid could take it precisely because most charging would be done during off-peak times.
I'll bet those graveyard shifts at the electric plants will start to resemble day shifts before too much longer!!

Yes. Infact, in terms of economics, since the utilization goes up - the rates for everyone falls !

I wish!!
What will PROBABLY happen is the electric companies will come out with a "there really are no peak/off peak times anymore, so ALL rates are now peak rates."
Grumble grumble. :evil:

Everything went exactly as it should have and the $1,000 off msrp price is locked in. I was told that I may actually get delivery of the vehicle in December... We shall see.
