Eos Energy Enterprises has signed a joint development agreement (JDA) with FlexGen Power Systems to develop a fully integrated battery energy storage system (BESS) solution using Eos’ zinc batteries and Flexgen’s Energy Management System (EMS).
FlexGen is the first major system integrator to announce a deal with a non-lithium-ion battery company that Energy-Storage.news is aware of.

Eos and FlexGen plan to develop and commercialise a comprehensive, integrated US BESS solution. This solution will combine Eos’ Z3 zinc-based long duration energy storage (LDES) systems, a US inverter and transformer package, with FlexGen’s HybridOS EMS.
This news follows the announcement that Eos received its first loan advance of US$68.3 million from the Department of Energy’s (DOE) Loan Programs Office (LPO) for the Mon Valley Works expansion project in Pennsylvania, US.
As reported by Energy-Storage.news, the overall funding of US$303.5 million will support around 80% of the cost of Project American Made Zinc Energy (AMAZE), the company’s roadmap to creating 8GWh of annual production capacity from automated lines by 2027.
Eos also secured a 400MWh standalone storage order with International Electric Power (IEP), which will be deployed at Haybarn Energy Reliability Centre, located at Marine Corps Base Camp Pendleton in San Diego County, California. The government of California approved a US$42 million grant to IPP IEP for the project.
Eos’ recent announcement confirms that the Haybarn Energy Reliability Centre will use the company’s Z3 Cubes, which the company claims are non-flammable and do not require cooling systems.
This string of recent activity could mean good news for Eos, which saw a low-revenue Q3 this year compared to last year. The company attributed the news to supply chain issues related to the Z3 cube. Creating a reliable, domestic supply chain for the technology could prove profitable for the company.
In April, FlexGen partnered with IPP Arclight and its subsidiary Infinigen Renewables to deploy a PV co-located 15MW BESS project in Puerto Rico. The BESS will utilise the system integrator’s HybridOS EMS.
Energy-Storage.news covered the November 2023 announcement that FlexGen and BESS-focused cell manufacturer Hithium made a 25GWh two-way agreement for battery supply and EMS. Of this, 10GWh will be batteries sold by Hithium to FlexGen, making it one of the year’s biggest offtake agreements between cell suppliers and system integrators.
