LF Energy Summit Europe 2026

Modern grid control systems require interoperable, scalable, and vendor-neutral data infrastructures. While CIM/CGMES has become the standard exchange format for power system models, many implementations still treat it primarily as a file format instead of a semantic data platform.

This session presents practical experiences from building modern utility control system components using RDF, SHACL, SPARQL, Apache Jena, and open-source tooling. We will show how semantic technologies can evolve from offline model exchange into high-performance, real-time knowledge graph infrastructures for power systems.

Topics include high-performance in-memory RDF graph processing, SHACL validation for operational grid models, lessons learned from Apache Jena internals, and the development of open-source tooling such as RDFArchitect and OpenCGMES.

The session shares real-world insights from developing software for transmission system operators and discusses how open semantic infrastructures can support interoperable and future-proof digital energy systems.
