When Will Electric Vehicles Act as a Grid Resource Under the V2G Paradigm?

The expected spread of electric vehicles (EVs) has led stakeholders to look at them not only as a burden for the grid but also as a resource, according to the concept of vehicle-to-grid (V2G). Electric vehicles can act as a mobile storage device and provide support to a grid based on intermittent and distributed energy resources (DER) but what is the basic requirement to enable an EV as a resource for the grid rather than a burden?
