Abstract: It is presented an apparatus for reducing reactive power consumption of auxiliaries in an electrical power generation plant. The apparatus comprises: at least one adjustable speed drive with an associated motor; at least one reactive power consuming auxiliary device; at least one sensor for measuring a reactive power; and a controller. The controller is connected to the at least one sensor and the at least one adjustable speed drive, for controlling the at least one adjustable speed drive such that a reactive power of the at least one adjustable speed drive at least partly compensates a reactive power consumed by the at least one reactive power consuming auxiliary device. A corresponding method and computer program product are also presented.
