GP JOULE Tech Stack

Integrated renewable energy supplier across generation, storage, mobility, and heat

Renewable Energy Power Generation Reußenköge, Schleswig-Holstein 501–1,000 employees Founded 2009 Privately Held

GP JOULE operates across the full energy value chain—wind and solar generation, green hydrogen production, heat networks, and EV charging—using a Microsoft-centric enterprise stack (Dynamics 365, Business Central, Power BI) paired with specialized CAD and geospatial tools (AutoCAD, QGIS). Hiring is accelerating with a 2:1 finance-and-ops to engineering ratio, reflecting operational complexity in procurement, grid management, and project scaling rather than software product development. Active projects span utility-scale solar and battery storage, heat network expansion, and charging infrastructure—each with distinct procurement and financing constraints.
