Stem and Nuvation Energy partner for North American BESS control solution

Stem Inc. (NYSE: STEM) announced a co-marketing agreement with Nuvation Energy to jointly promote a North American-made battery energy storage system control stack. The partnership combines Stem's PowerTrack Energy Management System and Unit Controller with Nuvation's Battery Management System.

The integrated solution addresses growing demand for domestically sourced energy infrastructure amid tightening regulatory requirements, including Foreign Entity of Concern restrictions and state-level legislation. PowerTrack EMS provides site-level scheduling, utility dispatch, and grid coordination, while Nuvation's BMS delivers cell-level monitoring and protection.

"Customers are asking for greater transparency, control and confidence in the technologies deployed across their energy assets," said Matt Tappin, President of Software at Stem. "This collaboration will allow us to deliver a more integrated solution that directly addresses those priorities."

Nuvation Energy has developed BMS technology since 2008, with products deployed across commercial, industrial, and utility-scale energy storage projects. The company's solutions are developed and manufactured in the United States and Canada.

Under the agreement, the companies will collaborate on joint marketing activities, including trade show participation and co-branded materials. They will also coordinate sales efforts on identified opportunities while maintaining independent commercial structures.

The integrated solution will undergo joint performance validation and testing before customer deployment. Stem will lead energy management system integration and controls across the battery storage and power conversion system, while Nuvation will provide BMS hardware and interfaces for integration.

According to the press release, some manufacturers are using rebranded products or minimally modified designs to meet compliance requirements rather than investing in North American engineering, potentially leaving safety and cybersecurity standards unaddressed.
