PG&E demonstrates first ever vehicle-to-grid charging

The concept of vehicle-to-grid (V2G) power sharing has been mentioned on our site quite a few times in the past. For one instance, check out our interview with Michael Brylawski, a member from the Rocky Mountain Institute. The basic principle here is that electric cars charged at night while electricity is cheap can actually give some of that power back during the day when electricity costs more, and the owners of the vehicle that is giving that power back can get a credit towards the purchase of electricity when the car charges back up. Make sense?

Don't believe that this can actually take place? Check out this article from Inside Green Tech. They interviewed Sven Thesen of PG&E on the subject. PG&E have been creating new advanced metering which will show you what is happening with the car, charging or giving back. Here is a quote, "Just plug your vehicle in at night, and we'll send a signal at 11, 12 or 1 a.m. to start your charging. When you get up in the morning, your car will be fully charged. You'll plug your car in at work. Maybe we'll need your electricity, and maybe we won't. If we do, you'll see a credit on your bill, and if not, you'll see nothing."
