LF Energy Summit Europe 2026

We present how the open Energy System Description Language (ESDL) is translated into GIS environments to enable interoperable and transparent spatial energy planning, across domains. ESDL is a modelling language designed to represent multi-carrier energy system components, their relationships, and dynamic behavior, while structuring assets, network topologies, and scenarios in a consistent way.

In the Netherlands the spatial dimension of the energy transition is critical and diverse stakeholders (grid operators, municipalities, industry, and modelers) have to exchange, aggregate, and iteratively refine energy scenarios. This makes a shared standard, that connects different models across domains (e.g. heat, gas and electricity) and seamlessly links to GIS, important.
In this session, we demonstrate how Esri and ArcGIS are integrating ESDL and explore what this means for interoperability and the open-source ecosystem. How can a leading GIS platform evolve into an open environment for open energy simulation models?

We will share the latest status of ESDL integration in both ArcGIS and QGIS, including practical examples such as hydrogen network simulations: https://arcg.is/9rP0y

Remedial Action Optimisation (RAO) is becoming a key operational capability to manage interconnected power systems across Europe. As requirements evolve and implementations mature, there is a growing need for coordination between stakeholders contributing to and relying on shared solutions.
This Birds of a Feather session is an open, collaborative forum around PowSyBl OpenRAO, bringing together developers such as Artelys, TSOs such as RTE, and RCCs such as Coreso to exchange on experiences, ongoing work, and upcoming priorities.
RTE and Artelys will present developments carried out on OpenRAO over the past year and those planned for the next (algorithmic improvements, countertrading within the optimisation core, …), with a focus on alignment with requirements from ongoing projects, notably SWE ROSC for Coreso. The session will also explore connections with related initiatives, including ToOP.
Rather than a one-way presentation, we will focus on interaction: participants will be invited to share plans, challenges, and expectations regarding OpenRAO. The objective is to foster convergence, encourage contributions, and strengthen a shared vision for OpenRAO within the LFE community.
