An electric car owner could save $ 3,000 per year

In theory, fleet owners will pay the cost of electric cars, whose lithium battery pack is the most expensive component. Referring to the work done by the University of Delaware, the chairman of the Federal Commission for Energy Regulation, Jon Wellinghoff said at a conference on the power grid last year that an owner of electric cars could earning $ 3,000 a year by selling services, such as frequency regulation, power grid operators.

Besides the technical difficulties, one of the obstacles to this type of application of the proposed energy return the vehicle to the power grid is linked to the network regulations that were designed around the power plants, instead of storing the distributed energy.

NRG Energy is putting in place a network of electric charging stations in public, as well as domestic cargo terminals, but the utility company and the University of Delaware did not indicate a date for the availability such a service energy release of the vehicle network.
