WHY BESS

The role of battery storage in data center power.

As AI workloads drive unprecedented power demand, battery energy storage systems have become a critical component of data center power architecture. BESS provides instantaneous response capability, load management, and resiliency that generation equipment alone cannot deliver.

Resiliency & Backup

Provide seamless ride-through during grid outages or generation transitions. BESS responds in milliseconds, protecting sensitive compute loads from even momentary power interruptions.

Peak Shaving

Reduce demand charges by discharging stored energy during peak consumption periods. BESS can significantly lower utility bills at large-scale data center facilities.

Frequency Response

Provide primary frequency response and spinning reserve services to support grid stability. Grid-forming inverter configurations enable islanded microgrid operation.

Generation Smoothing

Buffer the output of reciprocating engine and gas turbine generators to eliminate ramp-rate limitations and provide smooth, stable power delivery to critical loads.

CONTAINERIZED SYSTEMS

Containerized BESS Platforms

Containerized battery energy storage systems offer a modular, scalable approach to utility-scale storage deployment. Each container integrates battery modules, power conversion systems, thermal management and controls into a self-contained unit that can be deployed individually or in large arrays.

HYBRID INTEGRATION

BESS + Generation Hybrid Systems

Combining battery energy storage with reciprocating engine or gas turbine generation creates a hybrid power architecture that delivers the best attributes of both technologies. Generation provides sustained output capacity while BESS handles instantaneous response, load leveling and resiliency functions.

USE CASES

Where BESS delivers the most value.

01

AI Data Center Resiliency

Protect GPU clusters and AI training workloads from power interruptions. BESS provides millisecond-response backup that prevents costly compute job failures and hardware damage.

02

Behind-the-Meter Storage

Store energy generated on-site by reciprocating engines or gas turbines for dispatch during peak demand periods, reducing utility costs and improving overall project economics.

03

Grid Interconnection Support

Satisfy utility interconnection requirements for frequency response and reactive power support. BESS can accelerate grid approval timelines for new data center campuses.

04

Islanded Microgrid Operation

Enable fully islanded data center operation independent of the utility grid. Grid-forming BESS inverters establish voltage and frequency references for the microgrid.

05

Demand Charge Reduction

Discharge stored energy during peak demand windows to reduce monthly demand charges. At hyperscale facilities, demand charge savings alone can justify BESS capital costs.

06

Renewable Integration

Smooth the variable output of on-site solar generation and store excess renewable energy for dispatch during periods of high demand or low generation.
