POWER GENERATION SYSTEM

PROBLEM TO BE SOLVED: To provide a power generation system capable of presenting to a user the contribution to the reverse flow power of a fuel cell power generator in a power generation system including a solar power generator and the fuel cell power generator indicating with a graph and/or numerical values.SOLUTION: The power generation system includes: a first power generator 12 that generates and supplies the power to a power load 14 of a consumer having a power generation system 10; a second power generator 11 that generates and supplies the power to the power load 14 prior to the first power generator 12; and an indicator 13 that indicates the power generated by the first power generator 12 and the second power generator 11. The power generation system is configured so that the indicator 13 displays, using a graph, a first reverse flow power which flows reversely at least from the first power generator 12 to a commercial power supply system within a predetermined first period on the first period basis and the first power generated by the second power generator 11 in the first period is indicated on a graph on a display different from the other power using the first reverse flow power as the upper limit.
