The present invention relates to a power regulator and a process regulator, or a power regulating device (1) for regulating hybrid energy sources for an aircraft. The power regulator and process regulator (1) is equipped such that the requirement of a required means of a consumer (2) is measurable. In this arrangement the power regulating device (1) is equipped such that a first operating characteristic of a first energy source (3) and a second operating characteristic of a second energy source (4) are determinable. By means of the first energy source (3) a first requirement share can be generated, and by means of the second energy source (4) a second requirement share of the required means can be generated. The power regulating device (1) can regulate the first energy source (3) and the second energy source (4) such that depending on the first operating characteristic and on the second operating characteristic the first requirement share and the second requirement share of the required means can be provided to the consumer (2).
