On 31 October, the European Networks of Transmission System Operators for Electricity (ENTSO-E) and for Gas (ENTSOG) publish the outcome of their joint work on an Interlinked Modelling Framework. This work has been undertaken in close coordination with the European Network of Network Operators for Hydrogen (ENNOH) and is part of a regulatory process towards delivering cohesive multisector insights shaping Europe’s energy transition. 

The Interlinked Modelling Report provides a framework to support system planning across sectors. The Framework represents a system-wide approach, enabling comprehensive assessment of the interactions between electricity, gas, and hydrogen sectors in the respective Ten-Year Network Development Plans (TYNDPs). The Framework  addresses the transformation of Europe’s energy system, which is marked by increasing complexity, intensified decarbonisation objectives, and a growing interdependence between energy carriers.  

To plan the next steps, ENTSO-E and ENTSOG have created a roadmap for the future development of the Interlinked Modelling Framework. The Roadmap describes steps to embed cross-sectoral planning in the future electricity, gas and hydrogen TYNDPs, in the short- and longer-term. This includes for example further harmonising data of the sectors by 2028 and exploring the feasibility of a cross-sector assessment of system needs in a joint pilot study by 2030. ENNOH contributed to this work by providing input on hydrogen-related aspects. 

The Interlinked Modelling Report, including the Framework’s Roadmap, was consulted with the TYNDP scenarios Stakeholders Reference Group and are now being submitted to the European Commission and ACER as required by Regulations (EU) 2022/869, recently updated by Regulation (EU) 2024/1789. Stakeholders feedback will feed into the continuing work of ENTSOG and ENTSO-E, together with ENNOH soon to be fully established.
