TenneT Tech Stack

European transmission grid operator serving 43M+ across Netherlands and Germany

Utilities Arnhem, Gelderland 5,001–10,000 employees Public Company

TenneT operates 25,000+ km of high-voltage electricity infrastructure across the Netherlands and Germany, balancing supply and demand for 43 million people. The tech stack is heavily skewed toward industrial control (Ethernet/IP, IEC 61850, PowerFactory) and enterprise project management (Oracle Primavera P6, SAP S/4HANA), with emerging adoption of Python and GitHub Copilot — signaling a shift toward software-driven grid optimization. Pain points cluster around offshore project execution, standardized planning, and land rights — indicating the organization is scaling infrastructure delivery faster than internal processes can follow.
