Stem Expands its European Operations as Demand Surges for Solar, Storage and Hybrid Energy Solutions

Stem, Inc. (NYSE: STEM), a global leader reimagining technology to support the energy transition, today announced the expansion of its Berlin operations with a move to centralized and collaborative facilities. The new office underscores Stem’s commitment to advancing utility-scale solar, storage and hybrid solar-plus-storage projects across the EMEA region.

The enhanced 400-square-meter space nearly doubles workspace capacity, bringing Stem’s engineering, sales, and customer success teams closer to project developers and utility partners. The centrally located Berlin hub positions the team to address Europe’s most pressing technical challenges including hybrid solar-plus-storage integration, merchant market risk management, and optimization in negative pricing environments.

“This expansion underscores Stem’s commitment to embed engineering and customer expertise directly in Europe,” said Arun Narayanan, Chief Executive Officer of Stem. “Our partners are facing increasingly complex projects that demand proven execution, risk mitigation, and platform reliability. By expanding in Berlin, we’re strengthening local capabilities to deliver faster commissioning and the post-sales support that has become essential for successful solar and storage projects across the region and are well positioned for further growth across our regional teams.”

The Berlin hub is designed as Stem’s European competence center, centralizing teams with regional expertise focused on solving the most pressing challenges facing large-scale renewable projects today. By expanding technical depth and customer support in Berlin, Stem combines global expertise with local execution and service to help customers succeed in increasingly complex EMEA markets. Stem’s PowerTrack platform is already delivering results across multiple markets in Europe, demonstrating its ability to adapt to different regulatory and technical environments.

The expansion comes as Energy Management Systems have evolved into core infrastructure for project monetization and revenue assurance. Stem's newly launched PowerTrack Energy Management System (EMS), designed for solar, energy storage and hybrid solar-plus-storage control, requires the kind of local technical depth and rapid response capabilities that the expanded Berlin operations are already providing for customers in the region.
