5 Million Electric Cars Will Power Homes, Grid by 2017

The number of electric vehicles able to power buildings and feed the power grid will grow from 100,000 today, to more than 5 million in 2017, according to a new study by Pike Research, a market research firm for the clean technology industry.
The prospect of a power grid made more stable and efficient by millions of EVs connected to homes, and thus the power grid has been a much vaunted secondary benefit of widespread adoption of electric cars. So far it’s not even close to happening. But, the researchers predict, it will by the middle of the next decade after continued exponential EV adoption, especially in commercial fleets.
As of now there has been exactly one commercial test project of V2G possibilities. That was headed by the University of Delaware and PJM Interconnection, and it concluded in 2010 (PDF report). The data from that project will shape future plans for commercialization, Pike research predicts.
There are a few obstacles and disincentives for utilities to connect cars to the power grid, according to the report. One hitch to growth right now is that one Nissan Leaf on a block is not enough to interest a power company in building out vehicle-to-grid connections in an area. There needs to be a cluster of EVs close enough to each other to tempt a utility. Fleet vehicles, like these electric delivery trucks, are the best candidates for a cluster of battery power storage the researchers posit.
While EVs could take on excess power from utilities, something they certainly want, utilities could potentially lose money on power served to homes with vehicle to grid capacity. If car batteries are able to take and store the cheaper power offered in off hours, the car itself could be a cheaper power source for a home or business during the expensive peak daytime hours.
