Battery Energy Storage System

A battery energy storage system (BESS) is an advanced energy storage solution that captures and stores electricity for use when grid power is unavailable or when demand peaks. A BESS supports facilities that require continuous, reliable power, such as data centers, healthcare operations, and industrial plants.

Battery energy storage systems can operate independently or as part of a hybrid configuration that includes generators or other distributed power assets. These systems help balance load demand, improve energy efficiency, and provide resilient power during outages or grid disturbances.

With a complete battery energy storage system from Global Power Supply, critical loads remain protected and energy delivery remains consistent, even during unexpected power events.

Yes, a battery energy storage system (BESS) can replace a generator in many standby and backup power applications, but there are important factors to consider. A BESS provides clean, instant power without emissions or fuel storage, and it can operate independently from the grid when properly sized and configured. It also offers the flexibility to integrate with renewable energy sources for a more sustainable power strategy. However, unlike a generator that can achieve virtually unlimited runtime by adding more fuel, a BESS is limited by its stored energy capacity and typically requires more installation space. For many facilities, the most reliable solution combines both technologies, a hybrid system that pairs a BESS with a generator for extended runtime and enhanced energy resilience.

Adding an energy storage system battery provides businesses with improved energy resilience, operational efficiency, and long-term cost stability. A well-designed battery energy storage system (BESS) delivers reliable backup power during outages, stabilizes facility loads, and reduces dependence on the utility grid during high-demand periods.

BESS technology benefits a wide range of industries, including:

• BESS technology benefits a wide range of industries, including:
• Industrial and manufacturing facilities
• Off-grid and remote operations
• Distribution and logistics centers
• Healthcare and medical facilities
• Commercial and multi-tenant buildings

Global Power Supply offers scalable, factory-tested BESS units from leading manufacturers. These systems can be integrated into hybrid generator-BESS configurations for additional runtime, flexibility, and resilience.

Most modern battery energy storage systems use lithium-ion batteries due to their high energy density, rapid recharge capability, and long operational life. Lithium technology enables both UPS systems and BESS units to deliver consistent, efficient power with minimal maintenance.

Lithium-ion energy storage system batteries are ideal for demanding applications such as hospitals, industrial operations, and large-scale facilities. For organizations powering heavy equipment or hybrid generator-BESS systems, regular testing and maintenance help ensure long-term performance and reliability.

Global Power Supply offers professional inspections, evaluations, and maintenance services for BESS and UPS systems nationwide.

The duration of power provided by a battery energy storage system (BESS) depends on system capacity, load demand, and integration with supporting equipment such as UPS systems or generators. On average, a commercial BESS delivers approximately five hours of standby power, but configurations can be engineered for longer runtimes based on specific requirements.

Hybrid generator-BESS systems can operate for extended periods by automatically charging batteries while maintaining continuous power to critical loads. Whether grid-tied or entirely off-grid, a properly sized and calibrated battery energy storage system ensures dependable power delivery.

Renewable energy sources, conventional grid power, or a combination of both can power battery energy storage systems. Many facilities pair a BESS with a renewable energy source or other distributed energy resources to capture and store clean power for later use.

In addition, a hybrid generator-BESS system is a proven solution for facilities that require continuous, on-demand power. In this configuration, a diesel or natural gas generator can automatically recharge the battery energy storage system during periods of low grid availability or at optimal times to maintain peak efficiency.

For applications focused on peak shaving, frequency regulation, or energy cost management, BESS units can also draw energy directly from the electrical grid. Our engineering team can design a configuration that balances your sustainability goals with operational and budgetary requirements.

Global Power Supply offers a broad range of battery energy storage systems with capacities from 50 kWh to over 5000 kWh, available in mobile, hybrid, and stationary formats. Systems such as the Narada 125 kW / 233 kWh All-in-One Cabinet and Narada NESP series containerized BESS deliver scalable energy solutions for commercial and industrial power needs.

Intermediate options like the ANA Energy 100 kW / 50 kWh EBoss Hybrid provide a compact, flexible design for mid-sized facilities. Each BESS can be customized to align with your power demand, operational requirements, and future expansion plans.

We also have access to many more BESS systems depending on customer needs.

Yes. Global Power Supply provides turnkey installation, commissioning, and maintenance for all battery energy storage systems (BESS) and UPS systems we supply. Our technicians ensure each installation meets safety, compliance, and performance standards.

Regular preventive maintenance protects both the UPS and the energy storage system battery, extending equipment life and improving reliability. Our comprehensive service programs include inspections, testing, and system monitoring for consistent operation.

We also support maintenance for hybrid generator-BESS systems and backup generators across the United States.

Installation time for a battery energy storage system (BESS) depends on project scale, configuration, and site readiness. Smaller commercial systems can often be installed within several days to a few weeks. Larger containerized or hybrid generator-BESS systems may take several weeks to several months to complete, depending on complexity and permitting requirements.
Our project management team oversees each stage, from engineering design to commissioning, to align with your operational schedule and energy continuity goals. For critical projects or emergency deployments, expedited installation options may be available.
