1. A power management server, comprising:
a controller configured to
select two or more first facilities from among a plurality of facilities each having a storage battery apparatus;
after selecting the two or more first facilities, apply, to the two or more first facilities, first processing,
wherein
the first processing includes suppressing discharge of the storage battery apparatuses using a suppression ratio of discharge power amount, the suppression ratio being the same among the storage battery apparatuses of the two or more first facilities,
by the suppressing, a non-zero discharge power amount of the storage battery apparatuses is suppressed,
the controller is configured to
select, from the plurality of facilities, a second facility in which a remaining storage amount of the storage battery apparatus is equal to or less than a predetermined threshold before an expiration timing of a control target period, and
apply, to the second facility, second processing to shift a predetermined timing to a later timing on a time axis, the predetermined timing being a timing when the remaining storage amount of the storage battery apparatus is equal to or less than the predetermined threshold before the expiration timing of the control target period,
the controller is configured to select the two or more first facilities to which the first processing is applied in response to a total reducible capacity of the second facility not reaching a targeted reduction capacity even when the second processing is applied to the second facility, and
the controller is configured to select facilities other than the second facility as the first facilities.
