PROBLEM TO BE SOLVED: To provide a power plant system which allows a user himself/herself to have a power generating unit for private power generation regardless of problems such as an installation space and a server of the power plant system.SOLUTION: A server 4 has a power generation amount calculation part 42, a transaction amount calculation part 47, a balance calculation part 44 and an information display control part 45. The power generation amount calculation part 42 adds information on generated power amount proportionally divided according to power generation ownership unit number information 45b to member-owned power generation amount information 41d which is information on power amount owned by a member for each member. The transaction amount calculation part 47 subtracts a sold power amount from a power generation amount in the member-owned power generation amount information 41d. The balance calculation part 44 adds a power selling profit based on a change in the member-owned power generation amount information 41d to corresponding balance information 41e. The information display control part 45 transmits the member-owned power generation amount information 41d and the balance information 41e to a computer terminal 11.SELECTED DRAWING: Figure 2 |
