LF Energy Summit Europe 2026 Agenda Is Live
The full session schedule is now available for 15–16 September in Berlin, Germany. Two days of project deep-dives, production deployments, and community collaboration across every layer of the energy stack.
The full agenda for LF Energy Summit Europe 2026 is live. Alliander, Elia, E.ON, 50Hertz, Hydro-Québec, RTE, and TenneT are just some of the organizations presenting across two days in Berlin, 15–16 September.
This year’s theme is Develop the Modern Grid, Together, and the agenda reflects it. The 2026 agenda covers the full breadth of the grid, from transmission simulation and substation automation to EV charging firmware and home energy management. Below is a look at sessions worth putting on your calendar.
The Iberian Blackout, Analyzed with Open Source Tools
Researchers from RTE will present their analysis of the April 2025 Iberian blackout using Dyna⍵o, LF Energy’s dynamic simulation suite. ENTSO-E’s Expert Panel identified Dyna⍵o as the basis for its independent voltage stability study of the event. This is a direct demonstration of what it means for open source tooling to carry institutional weight at the level of a continent-wide grid incident.
OpenSTEF 4.0 Launch
The OpenSTEF team, co-presenting with SIA and Sigholm, will officially launch version 4.0 at the summit. The release session covers what is new in 4.0, including a genAI-powered documentation pipeline and a community member’s upgrade experience from 3.0. A companion hands-on tutorial will let participants get started with energy forecasting using the new release and the Liander 2024 open dataset.
Redispatch Without Black Boxes
Alexander Geiseler from E.ON Digital Technology will share their experience replacing a vendor-built forecasting solution for transformer load forecasting with an OpenSTEF-based approach. The session covers benchmarking results, lessons learned, and how E.ON navigated the organizational path from user to contributor.
Scaling Grid Security at TenneT with PowSyBl
Hugo Pfister and Jorn van der Landen from TenneT will describe how the Dutch transmission operator rebuilt its grid security analysis using PowSyBl combined with a cloud-native orchestration platform. Calculation runtimes dropped from minutes to seconds. The session covers the architecture and what it took to reach production.
OSPO Lessons from Across the Sector
Open Source Program Offices are emerging as strategic enablers inside grid operators and this year’s agenda has strong coverage. A panel featuring Jonas van den Bogaard (Alliander), Sven Fritzsche (Elia/50Hertz), Geethu Joseph (CRESYM), and Hugo Pfister (TenneT) will discuss the practical realities of standing up OSPOs in regulated energy organizations. E.ON will present how their OSPO built a framework for evaluating and connecting LF Energy projects to real business needs inside the utility. Sven Fritzsche will also give a solo session on Elia Group’s first year with their OSPO, including the publication of ToOp as a strategic open source project.
Connecting LF Energy Projects: A Mini-City Prototype
Researchers from Hitachi will present a miniature city-grid prototype connecting OpenSTEF, SEAPATH, PowSyBl, OpenGridFM, and OperatorFabric across a shared operational chain. The session is designed to answer a question many in the community are working through: how these projects fit together in practice.
More Across the Agenda
The full two-day schedule also features:
- EVerest: How software-defined charging is transforming the hardware lifecycle, and a bidirectional DC charging demo using EVerest, ISO 15118-20, and a full open source toolchain
- PowSyBl ecosystem: Sessions covering Open Load Flow, TSO cooperation, MTDC load flow, reinforcement learning agents for grid operations, MCP-driven simulation workflows, and production deployments at utilities
- CoMPAS: A two-hour tutorial covering UX improvements, substation specification, SCL quality validation, and live plugin development
- Phlowers and asset modeling: New open source tooling from RTE for overhead line simulation, plus Alliander’s family of thermal models for cables and switchgear
- Dyna⍵o: A tutorial covering Modelica tooling, PyPowSyBl integration, and parameter-sweep workflows, plus DyCoV for dynamic compliance verification
- Digital substations: Sessions on E4S interoperability, SEAPATH onboarding, SUSE enablement, and other open source substation initiatives
- Cybersecurity and sovereignty: Malcolm for OT network monitoring from Germany’s Federal Office for Information Security (BSI), supply chain attestation and reproducible edge environments from SUSE, and CRA/NIS2 compliance blueprints from SEAPATH
- Open source strategy: The CapEx/OpEx barrier to open source software investment, automated pre-publication checks, and OSPO best practices
- AI and foundation models: GridSFM from Microsoft Research, the OpenGridFM tutorial, and AINETUS for safety-critical grid operations
