About FlexGen

Accelerating the shift to flexible, scalable energy systems

Our Vision

Global energy is facing three fundamental mismatches: power isn't always generated when it's needed, where it's needed, or at the scale required by new large loads. Renewable generation, electrification, and unprecedented data center demand are making those mismatches more pronounced. Battery energy storage solves them by making energy available when, where, and how it is needed.

FlexGen has been building for this future for more than 17 years, delivering the systems, software, and services that turn variability into reliability at scale. We envision a world where storage is the backbone of a more flexible, resilient power system, and intelligent orchestration keeps energy supply and demand in balance.

What we do

FlexGen is a global team of energy specialists, engineers, and operators who bring together decades of energy, technology, supply chain and operational experience to build and operate the next generation of energy infrastructure.

Our commercial and global supply teams work alongside leading battery, PCS and technology providers around the world. These relationships create a continuously improving feedback loop that helps customers make better decisions earlier, move faster and get the performance and value they expect from their energy storage systems.

FlexGen HybridOS™, the leading EMS for battery, solar, and hybrid sites. It enables One-Touch Commissioning® to bring systems online faster and more predictably and provides controls, automation and analytics to enable customer teams, FlexGen’s Remote Operations Center, and field services teams to operate seamlessly for years to come. 

Since 2009, FlexGen has supported complex, high-stakes projects, delivering resilient, modular systems for data centers, industrial operations, and utilities alike.
