Powering data centers in the hyperscale era

AI is driving unprecedented demand for data center power. FlexGen delivers faster interconnection, smarter energy management, and the reliability AI workloads demand. 

Battery energy storage site

Current state

Four challenges reshaping today's data center energy strategies

As AI computing workloads scale, traditional grid infrastructure is lagging, leaving data centers to take on the scope and burden of on-campus power challenges.

Time-to-power and interconnection

Interconnection queues have grown 10× in a decade, with median wait times stretching 4–8 years.

SOLUTION:
Campus-level battery storage has become the fastest path to power. Batteries deploy in under a year, and enable flexible and interruptible interconnection agreements. 

Transient loads and power quality

AI workloads ramp power up and down in milliseconds, creating rapid fluctuations that propagate to the grid and on-site generation. 

SOLUTION:
The grid-forming PCS and site-level EMS of a battery energy storage system absorb rapid AI load swings and present a smooth, predictable profile to upstream power sources.

Multi-asset orchestration

Without coordinated control, conflicts between batteries, generators, and renewables lead to instability.

SOLUTION:
Intelligent EMS functions as a site-level microgrid controller, enabling seamless grid-to-island transitions, black start, and enforcement of interconnection requirements.

UPS constraints and power density

AI workloads drive power densities far beyond legacy UPS capabilities which lead to scaling limitations.

SOLUTION:
Utility-scale 4-hour batteries deliver millisecond response, integrated power quality support, unified backup, ride-through, and peak management from a single system.

Solving AI transient loads and multi-asset orchestrations

FlexGen's latest white paper takes a deep dive into architecture evaluations, simulation results, and commercial guidance for AI-driven transient power swings and multi-asset orchestration.

FlexGen for data centers

Manage the complexity of AI with HybridOS

HybridOS is the intelligent energy management system designed for the operational complexity of AI data centers.

Peak demand management

HybridOS automatically manages state-of-charge thresholds to discharge batteries during periods of high electricity demand to reduce peak consumption charges and grid exposure.

Power balancing

Dynamic coordination of generation and load across multiple energy assets. HybridOS continuously evaluates asset availability and operating limits to determine optimal real-time dispatch under all conditions.

Islanding and seamless transition

HybridOS enables the automatic and graceful isolation from the grid during disturbances — maintaining continuity of data center operations without service interruption.

Grid Resynchronization

HybridOS monitors grid voltage, frequency, and phase angle in real time — executing resynchronization at precisely the right moment to prevent transient disturbances to critical data center loads.

Black start

Manage transformer inrush current, sequences the energization of auxiliary systems, and coordinates the startup of large gas turbines or other generation assets before they assume control of voltage and frequency.

Low voltage ride-through

Modern BESS power conversion systems can ride through short-duration voltage events. This is critical as regulators increasingly require large loads to remain online during disturbances, preventing gigawatt-scale load loss.
