The disclosure relates to a method for allocating electrical energy within an electrolysis plant for producing oxygen and hydrogen. The electrolysis plant comprises a system control device and at least two management apparatuses. Each management apparatus comprises at least one management control device and at least two electrolysis devices. The allocation method comprises method steps and method sequences by means of which the electrolysis process can be particularly advantageously controlled. Thus, a particularly flexible design of the electrolysis process can be implemented, while at the same time high efficiency and an extended service life of the individual components of the electrolysis plant are achieved. The flexible design of the electrolysis process is reflected especially in an expanded range of application of the electrolysis plant.
