Steam delivery is expected to gradually increase in accordance with the planned operational ramp-up process.</p><p>According to the Company, operational performance to date has been encouraging and generally consistent with management's expectations for this stage of commissioning across key performance metrics, including system stability, responsiveness, operational consistency and overall performance under real industrial operating conditions. These early results provide additional support for management's belief regarding the potential scalability and repeatability of the bGen&#8482; platform across future customer deployments, subject to the successful completion of ongoing validation and commissioning activities. </p><p>"We are very encouraged by the system's performance during the initial operating phase" said, Avi Brenmiller, Chief Executive Officer of Brenmiller Energy. "Our aggressive growth plans, which include a broad mix of services for industrial customers, are built upon our unique technological foundation. The stronger and more capable this foundation becomes, the faster and more powerfully we believe will be able to grow."</p><p>"More importantly, Tempo is beginning to demonstrate the potential for TES to support the replacement of fossil-fuel-based heat generation in real-world industrial operations as the project progresses through commissioning. As we continue advancing this project, we believe it strengthens our position to pursue additional commercial opportunities globally and supports our long-term growth strategy."</p><p>"I am extremely proud of our outstanding team, which has successfully navigated the many challenges involved in executing such a complex first-of-its-kind project. Through their dedication, expertise and relentless focus on execution, they have delivered strong operational performance and achieved important milestones that have brought this project to its current stage," concluded Mr. Brenmiller.</p><p><b>Strategic Framework</b></p><p>Tempo is expected to serve as Brenmiller Energy's cornerstone commercial reference project, upon successful completion of commissioning and performance validation, providing a live operating showcase for prospective industrial customers, partners and project financiers evaluating TES solutions. Beyond validating the Company's technology at commercial scale, the project also demonstrates the broader capabilities of Brenmiller's 360BNRG framework, under which bGen&#8482; can be integrated with renewable generation and energy optimization solutions to support a range of commercial structures, including asset ownership and long-term operating models.</p><p>As global industries pursue practical and cost-effective pathways to decarbonize heat production, Brenmiller believes the successful execution of the Tempo project strengthens both its technological and commercial positioning in the growing TES market. The operational experience and performance data generated through the project are expected to support future deployments, strengthen customer confidence, and help accelerate the Company's commercial growth initiatives.</p><p><b>About the Tempo Project</b></p><p>The Tempo Project is Brenmiller's flagship industrial deployment and a major milestone in the Company's transition from technology development to scaled commercial execution. It includes a 32-megawatt-hour TES installation engineered to supply continuous industrial process steam and is designed to fully replace the site's fossil fuel boiler-based heat production following completion of the validation process. The system is expected to eliminate approximately 6,200 tons of CO&#8322; emissions annually. </p><p>Upon successful completion of the validation process, Tempo is expected to become one of Brenmiller's most significant commercial reference installations, demonstrating the Company's ability to deploy TES at industrial scale under real-world operating conditions.</p><p>The project represents the culmination of more than 15 years of technology development and is intended to serve as a blueprint for future industrial decarbonization deployments worldwide.  Brenmiller believes the operational experience and performance data generated through Tempo will strengthen customer confidence, support future commercial opportunities, and further support confidence in the scalability of the Company's bGen&#8482; platform.</p><p><b>About Brenmiller Energy Ltd.</b></p><p>Brenmiller Energy (NASDAQ:<a class="ticker" href="https://www.benzinga.com/quote/BNRG">BNRG</a>) is a leading clean energy company powered by proprietary thermal energy storage technology.
