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, you can develop pathways for the Swiss energy system and analyze the impact of technological, economic, regulatory, and societal developments.
The platform is maintained by the Nexus-e group at the Energy Science Center at ETH Zürich.
The CentIv module aims to co-optimize generation investment and operational decisions on the transmission system level for a target year or along an investment pathway over several years. The module is geared towards providing results with high temporal and spatial resolution from the perspective of a centralized decision maker. In its formulation, the module includes detailed dispatch, reserve and investment constraints for a wide range of flexibility providers and is tailored to give insight into how real-size power systems would evolve and cope with projected increase in intermittent renewable energy source generation. CentIv has an important role within both the investment and energy-economic loops of the Nexus-e framework.
Additional modules of the Nexus-e framework will be added to the open Nexus-e platform in the near future.
With this open-source version, you have access to a collection of data made public by the Nexus-e group; you can also run simulations with the CentIv module and explore the results it produces. You can get started right now.
You can also have a look at example results in our interactive webviewer.

New study on the potential role of hydrogen in the future Swiss electricity system.
Hydrogen and e-fuels and their potential role in future energy systems are hotly debated topics. Using The modelling platform Nexus-e, a team of researchers at the Energy Science Center at ETH has looked at the potential role of imported or domestic hydrogen or e-methane for the Swiss electricity system.
