PowerTrack EMS recognized as leading global solution for integrated edge-to-cloud control, monitoring, and performance capabilities for large-scale solar, storage, and hybrid assets

Stem, Inc. (NYSE:STEM), a global leader in AI-enabled clean energy software and services, today announced that its PowerTrack™ Energy Management System (EMS) has won The smarter E AWARD 2026 in the Smart Integrated Energy category. Organized by Solar Promotion International GmbH and Freiburg Management and Marketing International GmbH (FMMI), The smarter E AWARD is presented across five industry categories, honoring pioneers of the energy industry during its marquee exhibition, The smarter E Europe. The Smart Integrated Energy category specifically highlights technologies advancing the integration, management, and performance of clean energy systems.

PowerTrack EMS is Stem's edge-to-cloud energy management system for utility-scale solar, storage, and hybrid assets. The platform integrates on-site hardware with cloud intelligence to deliver real-time monitoring, advanced power plant controls, and portfolio-wide management, enabling asset owners and operators to accelerate deployment, maximize uptime, and increase revenue across complex clean energy portfolios. PowerTrack EMS combines flexible, vendor-independent architecture with robust cybersecurity to help projects move faster from commissioning to commercial operation.

The 2026 winners were announced during The smarter E Europe in Munich, Europe's largest alliance of exhibitions for the energy industry, bringing together Intersolar Europe, ees Europe, Power2Drive Europe, and EM-Power Europe.

"Winning The smarter E AWARD is an important recognition of the work our team has done to build software and controls that meet the real-world needs of large-scale BESS and hybrid plant operators," said Matthew Tappin, President of Software at Stem. "As renewable assets become more complex, customers have told us that they need technology that can help them operate with greater confidence, respond to grid requirements, and improve performance across their portfolios. PowerTrack EMS was built for that environment. With an intuitive on-site interface and purpose-built control architecture, it delivers the performance and reliability of a tailored system without locking customers into a single vendor."

The recognition for this award comes at a moment of significant momentum for PowerTrack as Stem continues to deploy the platform across industrial and utility-scale solar, storage, and hybrid projects worldwide. Backed by experience managing over 37 GW of solar assets and 800+ BESS sites across more than 55 countries, Stem is helping asset owners, developers, and utilities navigate an increasingly complex energy landscape, from first commissioning through the full operational lifecycle.
