How To Industrialize an Open Source Approach Around PowSyBl - Régis Le Drézen, Agnès Triponel & Sébastien Dinot, Sopra Steria

Waldbühne

Transmission system operators face structural challenges: sovereignty, security, safety, efficiency, digitalization …
In this session, Sopra Steria shares a practitioner’s journey of embedding LF Energy’s PowSyBl into a real TSO production program for RTE. We cover two concrete contributions shipped to the open source community: decoupling the network-viewer component from any frontend framework (React/Angular agnostic), enabling simultaneous dual-value display (P active and Q reactive) on grid lines. Beyond the code, we discuss how an IT company structures its OSPO, open source governance (Licence Rules Book), and the cultural shift required to move from “consumer” to “contributor” in a critical infrastructure context.
