Peak shaving reduces grid fees by smoothing electricity demand peaks — automatically and without affecting business operations.
Peak (load) shaving refers to the targeted reduction of short-term electricity demand peaks in companies. The goal is to lower the annual maximum demand and therefore significantly reduce the power price and grid fees — without affecting operational processes.
A battery energy storage system (BESS) detects load peaks in real time and supplies additional electricity exactly when grid consumption is about to exceed a defined threshold.
The storage system covers the extra demand for a short period — often just a few minutes — ensuring that the grid connection load remains stable, even when machines start up, compressors activate, or multiple chargers operate simultaneously.
This process runs fully automated and typically without affecting ongoing operations.
• Manufacturing plants with high starting currents or fluctuating machine loads
• Cold storage facilities or restaurants where compressors start simultaneously
• Charging infrastructure for electric vehicle fleets with multiple fast chargers
• Commercial buildings with elevators, HVAC systems, or other peak loads
• Combination with PV systems to further reduce grid demand
• Peak load (kW): highest 15-minute average demand per year, decisive for grid fees
• Storage power (kW): must be sized to absorb typical demand peaks
• Response time: typically < 1 second to limit peaks effectively
• Savings potential: often 10–50% of grid fees, depending on the load profile
• Grid tariff structure: RLM customers are charged based on their maximum annual demand
Peak load shaving is one of the most economically attractive applications for battery energy storage systems in commercial and industrial environments. It can significantly reduce electricity costs without interfering with operational processes.
The solution is automated, predictable, and scalable, making it a strong business case for companies with fluctuating electricity demand.
Our storage solutions are specifically designed for peak load shaving:
• Real-time detection and reduction of load peaks
• Automated smoothing of demand spikes
• Load profile analysis to size storage systems according to economically relevant peaks
