Stem Launches PowerTrack EMS, Expanding Global Product Suite for Standalone and Hybrid Energy Storage Control

Stem, a global leader reimagining technology to support the energy transition, announced its further strategic expansion into the standalone storage and solar-plus-storage control market with the launch of PowerTrack™ Energy Management System (EMS).

The expansion builds on Stem’s C&I leadership, with 13 of the top 15 US C&I players and 90% of leading US community solar asset owners standardizing on Stem’s PowerTrack platform. The Company currently manages more than 30 GW of solar assets and nearly 2 GWh of battery energy storage systems (BESS), providing deep operational expertise in diverse regulatory environments. This extensive deployment history and industry standardization provides customers with proven, reliable solutions backed by operational insights from diverse asset types, promoting optimal performance and minimizing operational risks.

PowerTrack EMS is an intelligent control system that manages battery charging and discharging operations while coordinating grid services and enabling revenue streams for energy storage projects. PowerTrack EMS integrates modular hardware and software architecture including PowerTrack Software for centralized portfolio management, PowerTrack Power Plant Controller (PPC) and PowerTrack SCADA capabilities, with a sophisticated edge user interface (UI) and hardware-agnostic unit controllers that eliminate vendor lock-in while supporting diverse equipment configurations.
