Eos Energy Unlocks Advanced Control and System Optimization with Launch of DawnOS: 100% U.S. Developed Battery Management System, Software, Controls, and Analytics Platform Designed for Security, Performance, and American Innovation

Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ("Eos" or the “Company”), an American energy company and the leading innovator in designing, sourcing, manufacturing, and providing zinc-based battery energy storage systems (BESS) manufactured in the United States, announced the launch of its new proprietary battery management system, software, controls and analytics platform, DawnOS, designed to revolutionize the way energy storage systems are managed, optimized, and integrated into the grid. Fully designed, engineered, and developed in the United States, DawnOS represents a new standard in American-made battery energy storage software – with technical excellence and national security designed into the platform.

Built with advanced analytics and real-time operational intelligence, DawnOS empowers system operators to maximize their battery asset value. The platform utilizes advanced State of Charge (SoC) to accurately track available energy, State of Health (SoH) to detect and correct imbalances between battery strings, reducing operating costs, and State of Energy (SoE) algorithms to estimate site-wide energy capacity enabling precise grid dispatch, revenue optimization, and improved grid coordination.

Purpose-built for the Eos battery chemistry and system architecture, DawnOS enables superior distributed control down to the independent battery module level, driving better system balancing, automated operations, and increased site availability. DawnOS addresses incumbent technology limitations by offering a comprehensive, IP-rich solution specifically designed to extract maximum value from Eos Z3 battery systems.

“As we continue to gain more field operating experience, we have been simultaneously developing DawnOS – marking a significant milestone in the advancement of our technology as we transition from a battery supplier to a provider of complete energy storage solutions,” said Francis Richey, Chief Technology Officer. “We built this platform based on direct feedback from our customers, creating a platform that makes it easier to monitor, manage, and realize the full value of Z3 Eos battery systems. With this software, our customers gain unprecedented visibility and control over their energy storage systems, enabling smarter decisions and greater returns with an American made product.”

Symbolizing the beginning of a new day and a new opportunity, DawnOS represents an Eos operating platform that empowers progress and transformation as the company ushers in the dawn of a new energy transition and drives toward American energy independence. At a time when critical infrastructure faces unprecedented cybersecurity threats and supply chain vulnerabilities, DawnOS delivers a secure, domestic platform with no foreign code and no external cloud dependencies.

“DawnOS was designed from the ground up with performance, cybersecurity, and safety in mind,” said Pranesh Rao, Senior Vice President of Storage System Engineering. “Using the knowledge of our chemistry and application experience, we have developed a customized control system that provides flexibility, scalability, and reliability, catering to the evolving demand for energy storage and supporting the future growth and rising need for BESS systems.”

Key features of DawnOS include:

• Automated System Balancing: Distributed controls perform automated balancing of modules within strings and of strings within cubes, maintaining system availability, extending asset life and minimizing operational and maintenance intervention.
• Real-Time Monitoring and Control: Seamless integration with battery hardware for instant performance insights.
• Unparalleled Flexibility in Energy Dispatch: Allows for dynamic discharge profiles without compromising system performance, health, or safety.
• Secure by Design: Hosted entirely on U.S. infrastructure, with proprietary Eos-developed code and no reliance on foreign software or cloud services.

DawnOS is now being deployed in all new Eos projects and can be integrated into select legacy projects to bring next-generation intelligence and performance to Eos’ fleet of long duration energy storage systems.
