Scaling Grid Security With Open Source - Hugo Pfister & Jorn van der Landen, TenneT Netherlands

Tuesday September 15, 2026 11:40 - 12:10 CEST

Waldbühne

The power grid is changing fast, and the systems behind it are under pressure. More data, tighter timeframes, increasing congestion, and regulatory requirements are pushing traditional grid security tools beyond their limits. At TenneT Netherlands, legacy tooling was simply no longer fast and adaptable enough to keep up with this new reality.

By combining the open source PowSyBl framework with a cloud-native orchestration platform (ReFlow), TenneT rebuilt its grid security analysis from the ground up. The result is a step change in performance and capability: reducing calculation runtimes from minutes to seconds and enabling a fundamentally different way of working.

This session will show how we:

- Moved from monolithic legacy tooling to a modular, scalable architecture
- Used open source to accelerate delivery and avoid vendor lock-in
- Established what it takes to run open source in a mission-critical environment
- Strengthened operator support by providing an integrated view across analyses through modular design
