A post-control electric power amount curve generating portion generates plural pieces of running control information indicating a changeable running method for each device and plural post-control electric power amount curves indicating an amount of main electric power. A post-control hot water storage amount curve generating portion generates post-control hot water storage amount curves each indicating an accumulated amount of hot water generated in a case where the fuel cell generates electric power based on the plural post-control electric power amount curves. A hot water storage completion determining portion determines whether the accumulated amounts exceed a specific heat capacity. A reduction amount calculating portion calculates plural energy cost reduction amounts produced before and after the change using the post-control hot water storage amount curves determined as not exceeding the specific heat capacity. A running method determining portion determines the running control information corresponding to the largest energy cost reduction amount.
