This power generation apparatus, power generation system, and power generation method advantageously control distributed power sources as a whole. A power generation apparatus includes a power generator that generates power to supply to a load and includes a controller that controls output of power generated by the power generator. The controller controls, when the total output of power generated by the power generation apparatus and other power generation apparatuses connected thereto exceeds the power consumption of the load, to adjust output of power generated by the power generation apparatus and the other power generation apparatuses based on at least one of information indicating the power generation efficiency and information indicating the degree of degradation of the power generation apparatus and the other power generation apparatuses.
