Energy management in KNX can include load shedding in order to prevent grid overload during peak demand.

Load shedding logic monitors the measured total power (e.g. DPT 14.056) and, when a configured limit is approached, disables loads in a defined priority order (typically water heater, then auxiliary heating, then ventilation, then comfort outlets). Each load is wired to a priority/disable object and re-enabled when consumption drops below a hysteresis threshold. This avoids exceeding the contractual subscription or activating a peak tariff and is a standard energy-management feature on KNX.

Always define a minimum on/off time per shed-able load to avoid rapid cycling of compressors and immersion heaters when the household load fluctuates.
