Zelestra Tech Stack

Vertically integrated renewable energy developer across wind, solar, and storage

Renewable Energy Power Generation Spain 501–1,000 employees Privately Held

Zelestra operates a full-stack renewable energy business—development through operations—spanning 38 GW of projects with 7 GW contracted or live. The tech stack reveals a traditional engineering-heavy org: CMMS, SAP, AutoCAD, SCADA, and grid-modeling tools (PSS/E, PowerWorld) dominate, reflecting asset-intensive operations and construction workflows. Recent hiring data shows engineering and ops scaling (72 of 133 open roles), while a new AI/ML forecasting platform in the project pipeline signals a push toward predictive maintenance and yield optimization—a layer most traditional energy operators lack.
