</p><p xmlns="http://www.w3.org/1999/xhtml">
Stem, Inc. (NYSE:<a class="ticker" href="https://www.benzinga.com/quote/STEM">STEM</a>), a global leader in AI-enabled clean energy software and services, today announced that Copec Flux, the renewable energy subsidiary of Copec S.A., is deploying Stem's PowerTrack&#x2122; Energy Management System (EMS) at the Granja Solar project in Chile. This development expands Stem's Latin America footprint and represents a meaningful step into the region's utility-scale hybrid market.

</p><p xmlns="http://www.w3.org/1999/xhtml">
The Granja project is an existing 135 MW PV project that Copec is retrofitting with a 420 MWh BESS to create a hybrid solar-plus-storage facility that allows Copec to supply energy to the national energy grid at more valuable times. As part of that expansion, Stem's PowerTrack Energy Management System (EMS) will serve as the site's master control system, providing the controls architecture needed to manage the integrated asset.

</p><p xmlns="http://www.w3.org/1999/xhtml">
Stem will provide its PowerTrack edge and cloud solutions to support site-level monitoring, controls, and operational visibility. The project will demonstrate how PowerTrack can unify data, improve oversight, and support more effective operation of solar and storage assets, while Copec Flux provides local market expertise, delivery capabilities, and operational support.

</p><p xmlns="http://www.w3.org/1999/xhtml">
"Partnering with Copec expands the reach of PowerTrack into key Latin American markets," said Matt Tappin, President of Software at Stem. "Beginning with Granja Solar, we have an opportunity to show how advanced monitoring and controls software can help customers improve visibility, streamline operations, and build a stronger foundation for long-term asset performance."

</p><p xmlns="http://www.w3.org/1999/xhtml">
Copec Flux operates as an independent power producer and also provides EPC and O&amp;M services across its renewable energy portfolio. That combination of asset ownership, local execution, and operational capability makes Copec Flux both a strong customer for Granja and an important collaborator as Stem develops a scalable model for localized delivery and support in Latin America.

</p><p xmlns="http://www.w3.org/1999/xhtml">
"The model we're developing at Granja Solar reflects where the energy transition in the region is heading: increasingly integrated, intelligent, and flexible renewable energy projects. By incorporating advanced control systems, we are able to manage energy more efficiently, delivering greater stability and value to the electrical system. This partnership with Stem combines cutting-edge technology with the local execution and operational expertise of Copec, further strengthening our position as a strategic partner for Chile," said Leonardo Ljubetic, Chief Development Officer at Copec.

</p><p xmlns="http://www.w3.org/1999/xhtml">
As Stem continues to expand in the region, Granja Solar is expected to serve as a reference point for future hybrid projects requiring advanced onsite controls, monitoring, and operational coordination. The companies see potential to extend this delivery model across additional projects in Chile and Colombia as demand grows for more integrated solar and storage solutions.
