<p><P>PROBLEM TO BE SOLVED: To propose an optimal rate menu, with a little labor, for a user having a number of places where electric power is consumed. <P>SOLUTION: An optimal rate menu proposing system 10 comprises a server 11 storing a database 14 wherein the results of demand of a user is recorded for each place to consume electric power, and a support program 20 and a terminal 12. The support program 20 extracts, from the database 14, the result of demand for each place to consume electric power of the user to whom rate menus are to be proposed, the extracted result of demand for each place to use electric power of the user is prepared into estimated consumption amount for each time zone for a rate division determined in the rate menu, estimated power rates in the case of contracting each of rate menus is calculated for each place to consume electric power based on the prepared estimated consumption amount and a unit price in each of time zones determined in each of rate menus, and rate menus optimal for that user are simultaneously proposed, regarding all the places to consume electric power, based on the estimated power rates. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
