Stem and Nuvation Energy Partner to Deliver Fully North American-Made BESS Control Solution
Stem, Inc. (NYSE: STEM), a recognized global leader in AI-enabled clean energy software and services, has announced a strategic co-marketing agreement with Nuvation Energy, a North American provider of advanced battery management and energy control solutions. This collaboration is aimed at jointly promoting a fully North American-designed and manufactured battery energy storage system (BESS) control stack, addressing rising market demand for secure, compliant, and domestically sourced energy infrastructure.
The partnership brings together two complementary technologies to create a unified and highly capable control architecture. Stem contributes its PowerTrack Energy Management System (EMS) and Unit Controller, while Nuvation Energy provides its sophisticated Battery Management System (BMS). The result is an integrated control layer that spans from cell-level battery intelligence to system-wide energy optimization and grid coordination.
Stem’s PowerTrack EMS plays a central role in managing site-level operations, including energy scheduling, utility dispatch, and grid services participation. It also enables advanced edge-to-cloud telemetry, providing operators with real-time insights and analytics for improved decision-making. Meanwhile, Nuvation’s BMS delivers granular monitoring and control at the battery cell level, ensuring safety, performance optimization, and accurate state-of-charge calculations. By combining these technologies, the companies aim to deliver a more intelligent, efficient, and resilient energy storage solution.
The collaboration comes at a time when the energy sector is undergoing significant transformation, driven by increased renewable energy adoption, grid modernization, and heightened regulatory scrutiny. In particular, tightening regulations in the United States—such as Foreign Entity of Concern (FEOC) restrictions and various state-level requirements—are reshaping procurement strategies for energy storage developers, utilities, and asset owners. These stakeholders are increasingly prioritizing solutions that meet not only performance expectations but also strict compliance, cybersecurity, and supply chain transparency standards.
Matt Tappin, President of Software at Stem, emphasized the importance of these evolving customer expectations. He noted that energy asset owners are demanding greater transparency, control, and confidence in the technologies they deploy. According to Tappin, this collaboration enables Stem to deliver a more integrated and robust solution that enhances system performance, reliability, and long-term value. By combining advanced software intelligence with reliable hardware control systems, the partnership aims to address both operational and regulatory challenges facing modern energy infrastructure.
The agreement also highlights a growing concern within the industry regarding the authenticity of “compliant” solutions. As regulatory requirements tighten, some manufacturers have attempted to meet compliance thresholds through superficial measures, such as rebranding existing products or making minimal modifications to foreign-designed systems. While these approaches may technically satisfy certain rules, they often fall short in addressing deeper concerns related to safety, cybersecurity, and long-term reliability.
Nuvation Energy’s CEO and CTO, Michael Worry, addressed this issue directly, underscoring the importance of delivering solutions that meet both the letter and the spirit of regulatory frameworks. He explained that the joint offering provides a credible and technically robust alternative, with critical control electronics designed and manufactured entirely in North America. This approach not only ensures compliance but also enhances trust and transparency for customers navigating an increasingly complex regulatory landscape.
Nuvation Energy brings a strong track record to the partnership, having developed battery management system technology since 2008. Its solutions have been deployed across a wide range of applications, including commercial, industrial, and utility-scale energy storage projects. Notably, all of Nuvation’s products are developed and manufactured in the United States and Canada by a fully North American-based team, reinforcing the company’s commitment to domestic production and engineering excellence.
Under the terms of the agreement, Stem and Nuvation will implement a coordinated go-to-market strategy designed to maximize the reach and impact of their integrated solution. This strategy includes joint thought leadership initiatives, participation in industry trade shows, and the creation of co-branded marketing materials. By aligning their messaging and market engagement efforts, the companies aim to position their offering as a leading solution for customers seeking compliant and high-performance energy storage systems.
In addition to marketing collaboration, the companies will also align their sales efforts. This includes working together on identified business opportunities and coordinating closely with customers to ensure seamless solution delivery. Despite this alignment, both companies will maintain their independent commercial structures, allowing them to retain flexibility while benefiting from strategic collaboration.
A key aspect of the partnership is the commitment to rigorous testing and validation. Before deployment to customers, the integrated solution will undergo joint performance validation to ensure it meets the highest standards of reliability, safety, and efficiency. Stem will take the lead on energy management system integration, overseeing controls and telemetry across the BESS and power conversion systems. Nuvation, in turn, will supply the BMS hardware and ensure its seamless integration within the broader system architecture.
This collaboration reflects a broader industry trend toward vertically integrated and regionally sourced energy solutions. As energy storage becomes a cornerstone of modern power systems—supporting renewable integration, grid stability, and energy resilience—the importance of trusted, high-quality control systems continues to grow. By combining their respective strengths, Stem and Nuvation are positioning themselves to meet this demand with a solution that is not only technologically advanced but also aligned with evolving regulatory and market expectations.
Ultimately, the partnership represents a significant step forward in the development of secure, intelligent, and domestically produced energy storage solutions. By prioritizing transparency, compliance, and performance, Stem and Nuvation aim to provide customers with a reliable pathway to navigate the complexities of the modern energy landscape while supporting the transition to a cleaner and more resilient grid.
