Stem

Stem, Inc. is a global clean energy technology company founded in California in 2009. The company began with a vision to transform how energy consumption is managed, pioneering storage solutions by analyzing how utilities and developers use and are charged for energy. Over time, Stem shifted its focus to AI technology, introducing real-time optimization, forecasting, and grid services by combining hardware with intelligent software. This became a key market differentiator and positioned Stem as a leader in grid stability and renewable integration, offering services such as frequency regulation and demand response. In 2021, Stem became the first pure-play smart energy storage company to go public in the United States, listing on the NYSE. The company later acquired AlsoEnergy, a move that expanded its software capabilities and customer base. Today, Stem describes itself as a global leader reimagining technology to support the energy transition, helping asset owners, operators, and stakeholders benefit from the full value of their energy portfolio by enabling the intelligent development, deployment, and operation of clean energy assets. Stem's core offering is its integrated software suite, PowerTrack, which the company describes as the industry standard and best-in-class for asset monitoring. PowerTrack supports solar, storage, and hybrid assets across utility-scale and commercial & industrial (C&I) markets, providing advanced analytics, remote diagnostics, and performance reporting tools, including Software, Energy Management System, SCADA, Power Plant Controller, and Logger solutions. The suite consolidates previously separate brands such as AlsoEnergy and Athena into four standardized solutions: C&I Solar, Utility Solar, Storage, and Hybrid. PowerTrack Optimizer, formerly Athena, provides optimization capabilities. Beyond software, Stem offers Managed Services covering the full lifecycle of energy storage and hybrid systems—design, procurement, commissioning, operation, and optimization—to help asset owners maximize reliability, performance, and returns. The company also operates AIONA, an AI consulting and implementation practice that helps organizations identify high-impact AI opportunities, build working solutions on existing systems, and deliver measurable value. Stem reports that its solutions are used across 200,000+ sites worldwide, with global projects managed in 55 countries, from Germany to Japan and across North America. Customers have relied on Stem for nearly 20 years to maximize the value of their clean energy projects. The company's PowerTrack EMS won The smarter E AWARD 2026 in the "Smart Integrated Energy" category, described as Europe's leading renewable energy industry award.
