Power interchange apparatus, computer readable storage medium and power interchange method

A non-transitory computer readable storage medium that stores a program, wherein the program makes a computer perform a power interchange method,

• the power interchange method comprising:
• obtaining performance information being, for each of a plurality of first power customers that configure a first community, information about a power interchange performance between the first power customer and the first community;
• determining a contribution degree of at least one of the plurality of first power customers to a surplus power amount of the first community in a certain time period, based on information about the performance obtained in the obtaining of the performance information;
• obtaining an interchange request from at least one of the plurality of first power customers, to request for interchanging at least a part of surplus power of the first community in a future time period to a second community that is different from the first community;
• obtaining expectation information being information indicating an expected value of the surplus power amount of the first community in the future time period;
• and
• determining a power amount to be interchanged from the first community to the second community in the future time period, based on:
• (i) the expected value of the surplus power amount indicated by the information obtained in the obtaining of the expectation information;
• and (ii) the contribution degree in the future time period determined in the obtaining of the contribution degree.
