Newark, DE, U.S.A. — (METERING.COM) — April 30, 2013 – The University of Delaware and NRG Energy’s electric vehicle-to-grid (eV2g) project has become an official resource of PJM Interconnection with what the organizations say is the first proof that the technology can sell electricity from EVs to the power grid.

The University and NRG began work in September 2011 to commercialize the technology, which provides a two-way interface between EVs and the power grid that enables vehicle owners to sell electricity back to the grid while they are charging their EVs.

On February 27, the project – which is still under development with restricted test fleets towards a commercial offering – became an official participant in the PJM’s frequency regulation market. Since then, it has been selling power services from a fleet of EVs to PJM, whose territory has 60 million people in the 13 mid-Atlantic states.

“This demonstrates that EVs can provide both mobility and stationary power while helping making the grid more resilient and ultimately generating revenue for electric vehicle owners,” said NRG executive vice president Denise Wilson, who leads the company’s emerging businesses.

“Partnerships have been essential to the success of this initiative,” added University of Delaware president Patrick Harker. “It might be a few more years before a grid-integrated vehicle sits in every American driveway, but I’m excited to continue the journey.”
A key aspect of the technology is that it can aggregate power from multiple electric vehicles to create one larger power resource, rather than individual, smaller ones.

For grid operators, the technology serves as an innovative new approach to energy storage. It has the potential to balance the power provided by intermittent renewable resources such as wind and solar. Energy storage, such as large-scale batteries or those in a fleet of vehicles, can take the wind’s power generated at night and store it to use when demand is higher.

The technology is also expected to help managers of commercial EV fleets by providing revenue while the vehicles are parked, with individual EV owners to eventually follow.
