METHOD OF EFFICIENTLY MANAGING POWER

摘要

A group power management apparatus including a communication unit that communicates with a controller arranged at each installation location of an accumulation apparatus capable of storing power generated by a green generator that generates power derived from renewable energy to control transmission of the power discharged from the accumulation apparatus, an accumulated energy acquisition unit that acquires information about accumulated energy stored in the accumulation apparatus from a plurality of the controllers arranged at a plurality of the installation locations via the communication unit, and a group internal accumulated energy management unit that groups users of the controllers communicable via the communication unit and manages the information about accumulated energy for each group based on the information about accumulated energy acquired by the accumulated energy acquisition unit is provided.
