High-Performance Battery Energy Storage Systems With Advanced Controls

By combining modular lithium-ion battery storage with advanced energy management, battery energy storage systems (BESS) can support both front-of-the-meter and behind-the-meter applications, helping utilities, independent power producers and industrial customers operate more efficiently.

Scalable from 500kWh to 4GWh, BESS electrical systems can help reduce demand charges, provide crucial backup power and increase renewable energy utilization.¹

Front-of-meter and behind-the-meter applications

BESS electrical systems can support both grid-connected and on-site energy storage applications. Flexible architecture helps utilities manage peak demand, while commercial and industrial facilities can use it to reduce energy costs.

Grid-scale energy storage for utilities and independent power producers (IPPs)
On-site storage for commercial and industrial users
Backup power for critical infrastructure

Grid stability and peak demand management

BESS electrical systems use advanced control systems to help manage grid frequency and voltage fluctuations. Battery storage can absorb demand variations to help reduce strain on electrical infrastructure.

Frequency regulation and voltage support
Peak shaving to reduce demand charges
Load leveling across operations
Fast response times for grid services

Renewable energy integration and utilization

Store excess renewable energy and dispatch it when needed to help improve your clean energy investment. BESS electrical systems can help increase self-consumption of solar and wind generation.

Store solar and wind energy during peak production
Dispatch stored energy during high-demand periods
Help reduce curtailment of renewable generation
Support microgrid operations

Modular architecture for future expansion

Lithium-ion battery systems can scale as your energy needs grow. Our modular design uses pre-assembled, forklift-able enclosures that help simplify installation and reduce costs.

Scale from 500kWh to 4GWh capacity
Add capacity incrementally as needs change
Vendor-agnostic design for battery flexibility
Pre-assembled units can reduce installation time

Potential reduction in demand charges

Battery storage with solar can help reduce average monthly demand charges).¹The system helps lower peak electricity costs by shifting consumption away from expensive on-peak hours to lower-cost periods, delivering significant savings for commercial and industrial facilities.²
System availability for critical operations

Modern battery energy storage systems can achieve substantial uptime for reliable grid support.² Fast response times help stabilize operations and reduce unplanned downtime. Battery systems can absorb demand fluctuations to extend equipment life while providing backup power during outages.⁴
67% of storage focused on renewable integration

Energy shifting now accounts for 67% of new battery storage capacity additions.³ BESS systems can store excess solar and wind generation for dispatch during peak demand, helping enhance organizations’ renewable energy investment. This flexibility helps reduce curtailment and increases clean energy utilization.⁴

Frequently Asked Questions About Battery Energy Storage Systems

Our pre-assembled, forklift-able enclosures help reduce installation time compared to traditional build-on-site approaches. Project timelines depend on system size, site preparation requirements and utility interconnection processes. Modular design allows phased deployment, so facilities can bring capacity online incrementally rather than waiting for complete installation. Most commercial and industrial installations can be operational within weeks, while larger utility-scale projects may require several months for engineering, permitting and commissioning.¹

With advanced monitoring that tracks system health and performance, BESS operational and maintenance requirements are minimal compared to traditional generation assets. Vendor-agnostic architecture supports battery technology upgrades over time, helping extend system life as chemistry advances. Regular maintenance typically includes system inspections, firmware updates and battery performance monitoring. Energy management systems offer continuous visibility into operations, helping identify issues before they can impact performance. ¹

Battery storage delivers value through multiple revenue streams and cost reductions. Demand charge savings alone can be substantial for combined solar and storage systems.²Additional returns can come from energy arbitrage, backup power value and avoided equipment damage during outages.

Modular architecture allows organizations to start small and expand capacity as financial returns justify additional investment, helping manage upfront costs. Actual ROI varies based on utility rate structure, facility load profile and operational requirements.
