Load optimisation systems are used to temporarily and selectively disconnect individual commercial kitchen appliances from the power supply during periods of high electrical demand. The goal is to avoid peak loads without compromising the functionality of the equipment.

Together with its members, the HKI Association developed the national standard DIN 18875 – “Commercial Kitchen Appliances: Load Optimisation Interface”. This standard defines a uniform interface between kitchen equipment and load optimisation systems, providing the foundation for cross-manufacturer integration into energy management systems.

By integrating commercial kitchen equipment into an energy management system, electrical peak loads can be actively reduced without affecting hygiene or food safety requirements.

In addition, load optimisation contributes to grid-friendly and efficient use of electrical energy. By limiting peak loads in a targeted way, it supports energy management concepts and facilitates the integration of commercial kitchen equipment into existing electrical infrastructures. This enables demand-based planning of electrical supply capacities and ensures the efficient use of existing grid infrastructure.
