Eos-WATTMORE Pairing Boosts LDES Deployment
Eos Energy and WATTMORE announced a software-hardware collaboration on 24 August to integrate Intellect Operate into Eos’ Z3 long-duration energy storage systems, expanding controls and deployment speed. The partnership follows similar moves by Gamma Technologies with Gotion Illinois, Middle River Power and PowerTransitions fast-tracking BESS capacity, and Electra AI’s data-driven risk prediction with MinTech.
Eos Energy announced on 24 August a non-exclusive strategic collaboration with energy intelligence firm WATTMORE to embed WATTMORE’s Intellect Operate energy-management software into Eos’ Z3 long-duration energy storage (LDES) systems. The deal brings WATTMORE’s patented EMS, PPC and SCADA platform to Eos’ aqueous zinc-based Z3 batteries, which are 91 % domestic and meet Section 842 NDAA and FEOC compliance.
The partnership will deploy Intellect Operate on select customer projects and support integration with Eos’ DawnOS technology. WATTMORE’s Denver-based team will provide a pre-integrated controls option that combines FEOC- and BABA-compliant hardware with the software. The collaboration expands the controls ecosystem around Eos’ Z3 systems, streamlining deployment and supporting Eos’ strategy of delivering complete energy-storage solutions.
Eos and WATTMORE have previously worked together on a 3 MW/12 MWh project for Nebraska utility Lincoln Electric System, demonstrating the integrated solution’s grid-reliability benefits and scalability.
Eos also secured a Golden Dome for America contract from the U.S. Department of Defense to integrate mission-ready LDES for national defense. The company will deploy its Z3 solution for the controversial Golden Dome project announced by President Trump, though the project’s completion within the proposed timeframe, and altogether, remains highly uncertain.
Gamma Technologies and Gotion Illinois
Gamma Technologies announced on 19 August a strategic partnership with Gotion Illinois, the U.S. manufacturing subsidiary of China-headquartered Gotion. The collaboration pairs Gotion Illinois’ project experience and rapid U.S. growth with Gamma’s simulation and productivity platform, enabling faster, more accurate battery design across the development lifecycle.
Gotion’s U.S. $2 billion factory in Manteno, Illinois, opened in 2023. In May, Gotion partnered with Richardson Electronics to manufacture BESS at the Manteno plant. As Gotion expands its Gigafactory, it is adopting GT-AutoLion as its standard platform to provide a unified data foundation for chemistry, thermal, controls and battery engineering teams.
Across Gotion’s engineering organization, GT-AutoLion is used for design and validation workflows, safety analysis, and model calibration. The platform also supports mechanical-electrochemical coupling studies and evaluation of emerging chemistries such as sodium-ion and solid-state batteries.
Middle River Power and PowerTransitions Expand BESS
Independent power producers Middle River Power and PowerTransitions, acquired by Partners Group in 2025, are fast-tracking BESS capacity to improve U.S. grid reliability. As of 25 August, the IPPs have more than doubled their combined operating capacity to 4.8 GW and increased EBITDA over 60 %.
The companies co-locate BESS at legacy natural-gas plants, using existing interconnection points to bypass queues and reduce upgrade costs. Over the past year, Middle River Power integrated BESS into four natural-gas facilities in California and is constructing systems at five additional sites.
PowerTransitions has recently executed or finalized deals totaling 1.5 GW of capacity in New York and is advancing plans to deploy 600 MW of BESS.
| Project | Capacity (MW) | Location |
|---|---|---|
| 3 MW/12 MWh | 3 | Nebraska (Lincoln Electric System) |
| Combined | 4 800 | Various U.S. sites |
| New York deals | 1 500 | New York |
| Planned | 600 | New York |
The strategy of redeveloping brownfield sites allows the platforms to bring power online faster than greenfield alternatives.
Electra AI and MinTech Data Collaboration
Electra AI and the special-purpose acquisition company Iron Horse Acquisition II announced on 25 August a technical collaboration with South Korean firm MinTech. MinTech will feed operational data from its battery diagnostic and inspection equipment into Electra’s Battery Fleet Analytics solution, delivered on a SaaS basis through the AI Brain for Batteries platform.
Electra’s AI models will transform the data into real-time state diagnosis, analytics and risk prediction, aiming to flag emerging issues before they become failures.
Electra went public via a $250 million SPAC merger with Iron Horse in April. The company’s public-market performance mirrors broader trends in the BESS sector, where many SPAC-merged firms have struggled.
