Accelerate Interconnection and Future Proof Your Data Center with FlexGen

The rise of artificial intelligence has catalyzed the exponential expansion of data center computing needs and with it, the power demands required to operate these facilities. To meet this need, Battery Energy Storage Systems (BESS) will drive critical infrastructure development and maximize the efficiency of energy resources both in-front of and behind the meter.

Why Data Center Owners Choose Battery Energy Storage Solutions

FlexGen provides turnkey and hardware-agnostic solutions for designing, integrating, and operating energy storage assets to address the top four challenges of speed, cost, reliable cutovers, and power quality faced by data center developers.

Speed Up Interconnection

Avoid lengthy utility approval queues by managing and securing power capacity requirements at your facility. Batteries are the fastest-to-market solution for data centers to secure reliable power.

Reduce Energy Demand and Costs

Lower energy demand and costs by leveraging intelligent charging and discharging cycles that minimize grid reliance and reduce long-term energy expenses.

Provide Reliable Cutovers

Protect critical operations with millisecond-fast cutovers, avoiding the delays and risks of traditional mechanical solutions.

Pristine Power Quality

Integrate with existing power infrastructure or replace legacy UPS systems with 4-hour batteries- leveraging EMS software as the ultimate power control layer.

Demand Reduction

Leveraging the typical Utility-Scale 4-Hour BESS onsite (behind the meter) at data centers unlocks a variety of energy strategies, including demand reduction.

Peak Load Shaving & Demand Reduction

Discharge batteries during periods of high electricity demand, reducing peak consumption charges and overall energy usage.

Reduced Interconnection Requirements

Decrease the required utility capacity, simplify the interconnection process, and reduce the overall timeline. Leverage “interruptible interconnection” strategies to fast-track approvals, maintaining reliability during curtailment periods with 4-hour batteries.

Additional Revenue Streams

Capture additional revenue through grid services, capacity markets, frequency regulation, and wholesale/retail energy market participation.

Off-Grid Operations

An advanced evolution of the demand reduction model, BESS integrated with a variety of generation assets to enable complete grid independence.

Power Independence

A power solution that functions independently from utility connections, dramatically reduces utility grid dependency, and provides operation flexibility for data center loads.

Resilient Black Start Capability

Coordinated system black start functionality to maintain uninterrupted operations during utility outages.

Optimized Solar and Wind Integration

Intermittent energy resources are precisely sized and paired with batteries to support continuous off-grid operation for data center load.

Generator Replacement

BESS can be used as a direct replacement for conventional backup generators, transforming data center architecture while reducing overall project timeline and capex.

Accelerate Deployment Timeline

Batteries can be deployed significantly faster than diesel generators allowing data centers to become operational more quickly.

Extend Backup Duration

Configure systems with different battery durations providing comparable backup capabilities to traditional diesel generators.

Fast Grid-Forming Capability

Closely monitor the grid and UPS status to provide fast response or black start capabilities during utility outages.

Flexible Deployment Models

A centralized architecture to support the data center facility or a distributed approach where a single BESS block supports individual data center load blocks.

Power Quality with or without UPS

BESS can function as a medium-voltage line-interactive UPS system, addressing the power quality challenges of modern data centers while simplifying the overall system structure.

Enhanced Power Quality Management

Effectively mitigate voltage sags, swells, and frequency fluctuations seen by the critical load from utilities.

Fast Grid Forming Control

Mitigate power surges from AI training load profile and provide a smoother load profile.

CAPEX Reduction

BESS UPS can significantly reduce CAPEX and lead times of traditional UPS and backup generator data center components.

Seamless Operational Transitions

Enable uninterrupted transitions between grid-connected and off-grid operations without impacting critical data center loads.
