The benefits of this technology are mainly twofold: on the one hand, at the system level, V2G will make an important contribution to the energy transition, encouraging-as mentioned above-a shift to increasing shares of zero-emission renewable energy generation; on the other hand, it will result in a reduction in the cost of recharging for drivers, which will come in the form of a discount proportionate to the contribution made to the electric system by the vehicle during recharging.
