SWEET PATHFNDR just kicked off, with Nexus-e as the central tool
This June, the SWEET PATHFNDR (PATHways to an Efficient Future Energy System through Flexibility aND SectoR Coupling) project kicked off. PATHFNDR is a research project that aims to develop and analyse transition pathways for renewable energy integration in Switzerland. It is sponsored by the Swiss Federal Office of Energy’s SWEET programme. As the central tool for the consortium, Nexus-e will provide the scenarios, considering technical, economic, and social constraints for the national scale and regional scale.

Energy blog: Nexus-e and modeling for policymakers
Computational models can provide technical analysis to objectively evaluate the impact of energy policies. But they are rarely used in public policymaking due to the unclear quality of the input, non-transparent methodology, lack of validation, etc. Nexus-e makes a first step to tackle these challenges.

Pilot project release

In 2020, we have successfully completed Phase 1 of the Nexus-e project, including the pilot project “The role of flexibility providers in shaping the future energy system”. In this project, we studied how centralized and distributed technologies can address the increasing need for flexibility in the Swiss electricity system and how this affects the traditional operation of existing power generation units.

▪ What are potential pathways for the future Swiss electricity system?
▪ What is the need for flexibility in the projected Swiss electricity system?
▪ Who provides the required flexibility?
▪ What are the macroeconomic and environmental impacts of the future Swiss electricity system?

Nexus-e is an interconnected energy system modeling platform which aims to facilitate the energy transition in Switzerland by serving as a modeling infrastructure for researchers, students, and industry partners.

Using the Nexus-e platform, we develop pathways for the Swiss energy system and analyze the impact of technological, economic, regulatory, and societal developments.

The Nexus-e platform aims to

  • represent the whole energy system at regional and national scales,
  • combine strengths of top-down and bottom-up modeling approaches to account for complexity and multidisciplinarity in the energy system,
  • be a platform with a modular structure, well-defined interfaces, and transparent assumptions,
  • provide an infrastructure that is continuously used, extended, and improved by researchers from ETH Zurich, other institutions, and industry partners,
  • inform private and public stakeholders on topics concerning the energy transition to support public engagement.

With a current focus on electricity, the Nexus-e platform will include more components of the energy system, including energy supply and use, for example, related to buildings, transportation, or environmental impacts.
