Energy storage technology provider FlexGen Power Systems has closed the acquisition of assets and intellectual property (IP) from Powin.
The move positions FlexGen as a major supporter of more than 25 gigawatt hours (GWh) of battery energy storage systems (BESS) across more than 200 sites in ten countries with its software and services.
In early August 2025, the company received approval from the US Bankruptcy Court for the District of New Jersey for the acquisition.
The acquisition enhances FlexGen’s international standing within grid-scale storage solutions. It comes at a crucial time when energy infrastructures globally face increased demand for reliable performance.
FlexGen CEO Kelcy Pegler stated: “Batteries are critical to meeting the world’s growing demand for affordable, reliable electricity. This is more than an acquisition – it’s a reflection of FlexGen’s commitment to immediate continuity and the future of grid-scale storage.
“FlexGen’s proven operational excellence, hardware-agnostic software and commitment to innovation uniquely position us to maximise the value of these Powin assets today, while enhancing the reliability and performance of energy grids worldwide for years to come.”
FlexGen has also strengthened its workforce by integrating former Powin team members.
This ensures that customers experience seamless service continuity and retain critical technical knowledge for the supported systems.
Existing clients of Powin will continue to receive consistent support without interruption, and have the opportunity to improve system uptime and longevity by transitioning to FlexGen's proprietary HybridOS platform alongside their comprehensive lifecycle services.
Powin CEO Brian Kane stated: "Powin is proud of the technology and projects we’ve delivered. The goal was to ensure that those systems and customers are supported by an industry leader that provides the support and services enabling reliable, long-term operation.
“Based on their experience and reputation, and having collaborated with their team in recent days, we have full confidence that FlexGen is that leader.”
In April 2025, Trina Storage partnered FlexGen to implement a 371 megawatt hour energy storage system in the US state of Texas. The project, developed by SMT Energy, showcases Trina Storage's cutting-edge Elementa 2 solution.
