Power generation facility information management system and power generation facility information management method

A power generation facility information management system comprising:

• a power generation variation information analysis unit configured to analyze information about a form of a stop of power generation by a power generation facility, including a stop reason and a stop period of the power generation by the power generation facility, and information about a form of a variation in a power generation amount, including a reason for the variation in the power generation amount, thereby analyzing a possibility of reduction of an environmental impact caused by the power generation;
• and
• a calculation unit configured to calculate a reduction amount of the environmental impact when the stop in an avoidable power generation stop period is assumed to be avoided and calculate the reduction amount of the environmental impact when the avoidable variation is assumed to be avoided, based on an analysis result by the power generation variation information analysis unit.
