Commercial and Industrial Battery Energy Storage Systems
Kelly Generator & Equipment provides Generac stationary battery energy storage systems for commercial and industrial facilities. These systems also support institutional and critical-power applications.
Battery energy storage systems store electricity and release it when a facility needs it. As a result, organizations can manage energy use while strengthening site resilience.
Battery storage can charge during lower-cost periods and discharge when demand rises. This process can reduce peak demand charges and support time-of-use energy strategies. In addition, a BESS can store power from onsite solar for use after production drops.
Facilities can also use battery storage to support critical loads during short outages, brownouts, and power-quality events. However, runtime depends on the system size and connected loads.
For longer outages, battery storage can work with a Generac stationary generator. The battery responds quickly, while the generator supports longer operation.
Flexible BESS Configurations
Generac offers cabinet, containerized, and block-style systems for different energy and space requirements. Modular options also allow facilities to scale storage as their operational needs change.
Depending on the project, a system may support peak shaving, renewable integration, backup power, or microgrid operations.
KGE helps customers compare Generac BESS options and identify the right system for their facility. We consider the site, load profile, operating goals, and available space.
In addition, we can help customers explore how battery storage may work with stationary generators and industrial transfer switches.
Common Battery Storage Applications

Commercial and industrial facilities use stationary battery storage for several energy goals:
- Peak shaving and demand charge management
- Time-of-use energy management
- Solar energy storage and renewable integration
- Backup power for selected critical loads
- Grid support and energy asset management
- Microgrid and distributed energy projects
A properly selected BESS can serve more than one purpose. For example, the same system may manage daily energy costs and reserve capacity for outages. However, each project requires careful sizing and planning.
