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.

New paper published in Applied Energy

In this paper, we show the value of connecting models for assessing the transition of electricity systems until 2050.

  • We present the modeling platform Nexus-e in detail.
  • Nexus-e integrates top-down and bottom-up models of the energy-economic system.
  • Nexus-e assesses the coordinated investments in centralized and distributed resources.
  • Nexus-e allows to analyze the impact of changes in the an electric power system on grid security.
  • We show the benefits and limitations of the loops and interfaces within Nexus-e.

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.
