<p>Provided is a power management system including two or more sites. The two or more sites are connected by a distribution network including a power buying line on which power is bought, a power selling line on which power is sold, and a communication line on which information is communicated. Each site includes a power generating apparatus generating power using natural energy, and a power transmission/reception control unit transmitting power generated by the power generating apparatus to the distribution network and receiving power from the distribution network. The power transmission/reception control unit is operable, when power is sold by transmitting the power generated by the power generating apparatus to the distribution network, to transmit information necessary for selling power to the communication line of the distribution network.</p> |
