<P>PROBLEM TO BE SOLVED: To easily calculate an electric rate to be charged on a plurality of facilities even when there are two or more power supply systems. <P>SOLUTION: An electric rate calculation system 1 mainly includes: a proportional division power value calculation part 11a; an electric energy unit calculation part 11b; and an electric rate calculation part 11c. The proportional division power value calculation part calculates the power sharing rate of each of interior units 22a to 22f, and 32a to 32f based on interior unit information, and calculates a proportional division power value Wd of each interior unit based on the power sharing rate and a third electric energy W3. An electric energy unit calculation part calculates a supply electric energy unit Pr based on the first electric energy W1, the second electric energy W2, the first electric energy unit price Pr1 and the second electric energy unit price Pr2. The electric rate calculation part calculates the electric rate of each interior unit based on the proportional division electric energy Wd and the supply electric energy unit price Pr. <P>COPYRIGHT: (C)2010,JPO&INPIT |
