Core Applications: BESS Containers in Action
BESS containers aren’t one-trick ponies—they solve distinct pain points across cold chain operations. Below are their two most impactful use cases, each demonstrating the transformative power of battery energy storage systems in modern logistics.
Optimizing Refrigerated Warehouse Energy Use
Refrigerated warehouses face a common enemy: peak power demand. When cooling systems kick into high gear—such as after large restocking events or during extended warm weather spells—they cause a sudden spike in electricity usage. This surge triggers “demand charges” from utility providers, punitive fees imposed for straining the grid. These charges can inflate a warehouse’s energy bills by 20–30%, significantly impacting operational costs.
BESS containers address this challenge by acting as a sophisticated “peak-shaving tool,” leveraging intelligent energy management strategies:
- Charge during off-peak hours: BESS units actively store electricity when grid demand and associated costs are at their lowest, typically during overnight hours. By capitalizing on lower electricity rates during these periods, warehouses can accumulate energy reserves cost-effectively.
- Discharge during peaks: When peak demand periods arrive, BESS containers release stored energy to power refrigeration systems. This reduces reliance on the grid during high-cost intervals, effectively smoothing out energy consumption patterns and minimizing demand charges.
Real-World Win: German Refrigerated Warehouse
A 3MWh BESS container implementation at a German fresh produce storage facility showcases the tangible benefits of this technology:
