Stem, a global leader in AI-enabled clean energy software and services, has acquired the software assets of raicoon GmbH, a Vienna-based provider of automated fault detection and event management for solar asset performance. Financial terms of the transaction were not disclosed.
The acquisition is designed to enhance Stem’s PowerTrack platform by improving how operational data is analyzed and translated into actionable insights, helping renewable energy operators identify, prioritize, and resolve performance issues more quickly across their portfolios. Raicoon’s technology analyzes large volumes of asset-level data to detect performance anomalies and surface prioritized recommendations, reducing alert noise and streamlining operational workflows.
Raicoon’s solution is already deployed across solar portfolios in Europe, where it supports operators through automated fault detection and workflow management. Once integrated into PowerTrack, the capabilities are expected to reduce time to resolution, improve overall asset performance, and deliver a unified user experience for Stem’s global customer base.
The acquisition aligns with Stem’s 2026 strategic priority of strengthening its core businesses and driving deeper customer value within the PowerTrack platform. Existing raicoon customers will continue to be supported on the same platform and service model, now backed by Stem’s global resources and expanded software capabilities.
Stem trades on the NYSE under the ticker STEM.
KEY QUOTES:
“Customers are looking for clearer, more actionable insights from their energy assets, not more noise. This acquisition further strengthens PowerTrack by enhancing our ability to automatically surface and prioritize the issues that matter most, helping operators resolve performance problems faster and act with greater confidence.”
Matt Tappin, President of Software, Stem
“Operators don’t need more alerts, they need decisions. raicoon was designed to close that gap by automatically identifying what’s wrong, what matters, and what to do about it. PowerTrack is already a leading platform for managing clean energy assets, and we’re excited to see our technology strengthen it further. As part of Stem, we can deliver that to a global customer base on the platform that already sets the standard for clean energy asset management.”
