Power-generating units and compressor units are arranged in a compressed-air energy storage power station. According to one aspect of the invention, a common grid connection transformer is arranged, to which the power-generating units and the compressor units can selectively be connected. According to a further aspect of the invention, the power-station installation is subdivided into a power-generating area (I) in which the power-generating units are arranged, a switching and voltage-conversion area (II) in which a grid connection transformer is arranged, and a compressor area (III) in which the compressor units are arranged. The stated areas are arranged physically separately from one another. Power-station installations according to the invention can advantageously be combined to form modular power-station centers, which advantageously have common voltage rails and media rails.
