Not all Battery Energy Storage Systems work in the same way! But what is a Battery Energy Storage System, and why do industrial and commercial applications use different battery technologies? A BESS stores electricity in rechargeable batteries and supplies power when it is needed, helping businesses manage power interruptions, peak-hour demand and solar power usage.

There are four major types of Battery Energy Storage Systems: Lithium-ion BESS, Lead-acid BESS, Flow Battery BESS and Sodium-based BESS. Each technology has its own characteristics, storage capabilities and applications. Understanding these differences can help you identify the battery storage solution best suited to your facility, factory, or commercial building.
