When profit is generated by the electric power transaction by the bidding, the electric vehicle VPP management terminal 2250N calculates an amount to be allocated corresponding to the reverse transmission of the electric vehicle among the profit amount, and the calculated amount is calculated by the electric vehicle. It can be delivered to the registered electric vehicle VPP management terminal 2250. In addition, the electric vehicle VPP management terminal 2250 may pay the received amount to a virtual account of a corresponding electric vehicle owner.
