  "textContent": "In a case where a distributed generation such as a solar power generation system and an electricity accumulation apparatus are introduced to the side of a customer, an electric power from the distributed generation that is charged to the electricity accumulation apparatus cannot be caused to inversely flow to a power grid (a sale of the electricity) because it cannot be determined whether the electric power charged to the electricity accumulation apparatus is the electric power that comes from the power grid or the electric power that comes from the distributed generation. In the electricity accumulation apparatus including a dedicated charge terminal that connects to the distributed generation such as the solar power generation system and a grid-dedicated discharge terminal that connects to the power grid, a grid-dedicated charge terminal that connects to the power grid and a discharge terminal for discharging to an electric load such as an electric apparatus, the distinction with respect to an electric power charged to the electricity accumulation apparatus can be made between an electric power generated by the distributed generation and an electric power generated by the power grid, by providing an electric power measurement device for each charge terminal and each discharge terminal that connect to the distributed generation, and thus charge and discharge control can be performed.",
