The invention relates to an electricity supply apparatus, an elevator system and a method for limiting the electricity consumption of an elevator system. The electricity supply apparatus according to the invention is fitted to supply electricity to one or more devices in an elevator system. The minimum value of the permitted supply voltage with which the apparatus still operates is determined for one or more appliances of the elevator system, and the electricity supply apparatus is equipped to change the supply voltage of the one or more appliances of the elevator system towards the minimum value of the permitted supply voltage for limiting electricity consumption of the elevator system.
