Stem PowerTrack EMS User Interface

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.

"PowerTrack EMS represents a pivotal expansion of Stem's capabilities for standalone storage and hybrid assets," said Matt Tappin, President of Software Products at Stem. "We're combining PowerTrack’s proven background in solar monitoring and with Stem’s history as a pioneer in storage to help operators facing the unique challenges of controlling advanced solar and storage assets. We’re excited to offer a complete technical stack necessary for safe, optimal, and profitable storage operations from commercial to utility-scale projects in the US, Europe and beyond."

Solar, storage, and hybrid projects are rapidly expanding across the US and Europe. Operators, however, face significant challenges in controlling these complex assets, managing competing revenue streams between solar and storage, and navigating increasingly sophisticated grid requirements that demand seamless integration between renewable generation and energy storage capabilities.

PowerTrack EMS in intended to tackle these challenges through a complete technical stack that combines onsite hardware with industry-leading, configurable cloud software to deliver real-time monitoring, advanced control capabilities across entire energy portfolios without black-box limitations that restrict future flexibility.

A differentiation in the market, PowerTrack EMS users will always retain full ownership of their EMS infrastructure without mandatory subscriptions or vendor lock-in that could restrict operational flexibility.

Key Capabilities:

• Unified hybrid control to manage solar generation and battery storage as one integrated system, enabling maximum revenue capture and enhanced performance
• 32% reduction in engineering hours through pre-configuration, AI-enabled tuning and remote commissioning capabilities
• 99.99% controller reliability ensuring consistent revenue streams and eliminating downtime
• Sophisticated control modes enabling participation in diverse grid services markets, with further control modes in development
• Advanced "value stacking" capabilities to maximize revenue across multiple applications
• Future-proof architecture supporting seamless asset expansion or hybridization with transparent, flexible software providing full system visibility and preventing vendor dependencies that limit scaling flexibility.

The solution will serve utility-scale and C&I projects for international developers, EPCs, integrators, and existing PowerTrack customers seeking storage integration or hybrid optimization. Manufactured and pre-configured in the United States, PowerTrack EMS is immediately available globally with comprehensive deployment support.
