A power supply system has a server (S-1) communicating with a user terminal (32, 33) at a user site (A) receiving power from a selectable one of a plurality of power supply systems (G-1 to L-1, G-1 to L-2, G-2 to L-3). The server collects information about abnormalities caused in a power supply system related from abnormality detectors (20, 21). The server determines whether the power supply system from which the user is currently receiving power is normal or abnormal; if the power supply system is abnormal, the server sends, to the user terminal, information about normal power supply systems from which the user is able to receive power. |
