Here's a report from Federal Energy Regulatory Commissioner Jon Wellinghoff, followed by the official agenda from the event and some more general comments about V2G. We hope soon to add a photo or two of the event at http://www.calcars.org/­photos-leaders.html . This demonstration, for the first time involving a utilty transmission operator, expands on previous demonstrations of "running the meter backwards" by PG&E and Google.org.


JON WELLINGHOFF
We had a incredible day here at FERC with Dr. Willett Kempton of U. Delaware, Diarmuid O'Connell of Tesla, and David Sandalow [of the Brookings Institute, author of the new book, Freedom From Oil] and a Prius PHEV converted by A123. We put on a two hour seminar on V2G for the Chairman of FERC, Joseph Kelliher, and two other FERC Commissioners, Phil Moeller and Suedeen Kelly. Also attending were numerous FERC staffers as well as utility representatives and members of the press. Fox News had cameras here to cover the event.

The purpose of the seminar was to first discuss and then actually demonstrate V2G capability with a converted vehicle to the regional transmission operator, PJM. Dr. Kempton brought an eBox (Scion converted to EV) by AC Propulsion that had been enhanced with the communication hardware that is currently used by a small power plant to communicate to PJM.

We had the IT Director of PJM present. He had a laptop that was wired to the PJM control center via the Internet. From the laptop he was able to see the eBox vehicle and communicate with it just as if it were a generator and provide signals to it to supply grid support of frequency response. He indicated that the response time was literally milliseconds -- the fastest frequency response time he has ever seen from a grid asset like a generator. We were able to physically demonstrate, by running the electric meter connected to the vehicle both forwards and backward at the command of PJM, the feasibility of V2G ancillary services to the wholesale electric grid.

This is the first time to my knowledge this has ever been publicly demonstrated. It was the most exciting and historic event I have ever witnessed in the electric industry in my 35 year career.

FURTHER COMMENTS AND NOTES ABOUT V2G
We've gotten some good feedback about our 10/22/07 posting, "World's First V2G Demo: Xcel/Hybrids Plus/V2Green/US Lab+Ford Escape Hybrids" http://www.calcars.org/­calcars-news/­861.html which included some cautions about not overstating the benefits or immediacy of V2G. The most helpful comment was a suggestion that we begin to separate out the many different aspects of what happens when you plug in cars: each of them has technologies, business cases, pros and cons and timetables. They break out first into three categories:

Grid-To-Vehicle (G2V): for instance, when the power grid operator controls when it sends power to recharge fleet and personal vehicles. In contrast for instance to appliances that are in use, if the car is available to be charged all night, the grid could decide to charge for a few minutes, stop and then restart, with no negative consequences to the car but significant benefits to the grid.

Vehicle-To-Home (V2H): when the car is integrated with the home network, with "smart appliances" and "smart meters" like those that are coming in the next few years across California. This can provide backup power to the house, for instance. Southern California Edison's project with Ford may focus on this.

Vehicle-To-Grid (V2G): a fuller integration of the car with the power generation industry. It may require fewer cars than other applications, and it may require higher-power connections to permit rapid transfers of substantial amounts of energy.

We are hoping, with other involved parties, to get the resources and help to be able at some point to provide a more systematic introduction to V2G for non-technical policy analysts, journalists, PHEV advocates, etc.
