The invention relates to a lift system (ES1,..., ESm) with a lift unit (E1,..., En) that is connected to a power supply network (SG), said lift system being controllable by a lift controller (EC1,..., ECm), taking into account first control information items (ci1), based on local requests from users. The lift controller (EC1,..., ECm) receives second control information items (ci2) from the power supply network (SG) which contain status data for the power supply network (SG). The first and second control information items (ci1, ci2) are evaluated by the lift controller (EC1,..., ECm). In order to allow energy-optimized operation, the lift controller (EC1,..., ECm) influences an operation of the lift system (ES1,..., ESm) determined by the first control information items (ci1) on the basis of second control information items (ci2). A monitoring unit (NM) that determines status data for the power supply network (SG) and provides information for the loads is connectable to the power supply network (SG). On the basis of the load on the power supply network (SG), the monitoring unit (NM) creates second control information items (ci2) for the lift controller (EC1,..., ECm), according to which the lift system (ES1,..., ESm) is controlled in accordance with the first and second control information items (ci1, ci2) in such a manner that the required control energy (ER) for the power supply network (SG) is reduced.
