A load management system (LMS), often also called “energy optimization, load optimization, peak load management system”, manages the electrical power within a system and reduces the amount of power required at the same time in order to reduce costs. For this purpose, an LMS continuously records the loads of consumers and the main feed-in in order to then decide when, where and how much power needs to be reduced. This is done by briefly switching off static loads and thus reducing the output of the entire system by extending the duration of the energy requirement. In properly configured systems, this is done in such a way that the employee does not notice the switching process.

Modern, dynamically controllable loads are infinitely variable and therefore only consume the power released by the load management system.
