Energy Storage Systems

Understanding Energy Storage Systems: Devices That Store Energy for Later Use

What are Energy Storage Systems?

Battery Energy Storage Systems (ESS) are utility-scale reservoirs of energy. The most common ESS look like shipping containers and are filled with racks of lithium-ion batteries that store and transmit energy to the grid. 


How Can Energy Storage Systems Help?

ESS is helpful for a variety of reasons including:


Consumers need energy at different times of the day. When using ESS, energy providers can store energy to distribute later.

Emergency Backup

ESS can serve rapidly as a generator to keep the grid running or assist with getting it online faster in the case of a major outage. 

Grid Services

ESS can provide voltage control, frequency regulation, and reserve capacity to the grid during critical energy need events. 

Peak Shaving

ESS can lower energy costs by augmenting energy supply during peak demand times. 


Community Benefits

Property Taxes
Local schools and government supported through taxes paid by Qcells.
Created during construction and through the life of the project.
The grid power made energy more consistent and affordable.

Redundant Safety And Regulations 

ESS is a safe and reliable system because of the rigorous industry standards, regulations, built-in safety mechanisms, and cooperation with local fire departments. There are several redundant safety features that provide both active and passive mechanisms to prevent and contain a potential fire.


Physical Containment
Physical containment of ESS by the metal containers that house equipment.


Fire Detection
Each battery has 24/7 automated fire detection and extinguishing capabilities built-in.


Suppression Systems
Containers come equipped with cooling, ventilation, and fire suppression systems.
