Cat® Battery Energy Storage Systems (BESS) store power and deploy it when and where it’s needed most, helping businesses improve uptime, reduce fuel consumption, and optimize energy use. From renewable integration and microgrids to backup power and remote operations, Cat BESS delivers flexible, reliable storage solutions that adapts to changing power demands.
When it's time to call upon your energy storage, whether it's to discharge your energy quickly for grid stability or a slower transition from renewable sources to battery, your BESS product can either manually or automatically dispatch power. You can even monitor energy market conditions and avoid energy peak charges. All of this is made possible with our Distributed Energy Resource Management (DERM) software, Cat AMP. Watch our Cat AMP demo to see how we can help you.
Flexible Energy Management
Use energy from multiple sources and deploy it where it’s needed most.
Potential Fuel Savings
Using BESS alone or paired with a generator set can reduce fuel consumption.
Reduced Noise
Support quieter operation compared to generator-only power systems.
Grid and Utility Support
Help manage peak demand and support grid stability.
Lower Energy Costs
Cat® AMP dispatches assets like BESS at the optimal time, avoiding peak energy charges.
We offer a wide range of BESS products designed to help manage changing power demands, reduce fuel consumption, and support efficient operations.
The systems feature flexible, scalable, and modular designs to support a broad range of distributed energy system applications and equipment charging stations. Equipped with grid-forming Cat Bi-Directional Energy Storage Inverters, the flexibility and robustness of Cat BESS modules make them ideal for a broad spectrum of applications.

Learn MoreA. A Cat BESS is a mobile power solution that stores energy and delivers it when you need it. It helps improve reliability, power quality, and flexibility, whether you’re supporting renewable energy, managing peak demand, or keeping operations running smoothly on a jobsite.
A. In a hybrid power setup, Cat BESS works alongside generator sets to balance how and when power is used. It can switch between stored energy and genset power automatically – helping reduce low-load operation, support efficient performance, and manage noise and runtime. All while keeping uptime the priority.
A. Cat BESS systems can typically recharge in about four hours, depending on the application. They use advanced lithium-ion battery technology and come in multiple sizes, including:
Both 50 Hz and 60 Hz options are available to fit different operating needs.
A. Cat BESS are ideal for applications where power demand fluctuates throughout the day or quieter operation is needed.
Common use cases include:
They’re especially useful for handling low-load periods or providing silent power when it matters most.
A. Yes. Cat BESS can be monitored remotely using telematics with two-way communication. This gives you real-time visibility into performance and helps you make smarter operating decisions. Combined with support from your Cat dealer, it’s a solution designed to stay reliable over time.
