New model intercomparison study

Solar PV will be a key technology of the Swiss energy transition according to new model intercomparison study.

Jonas joins Nexus-e as the new manager

Jonas Savelsberg takes over the role of Nexus-e manager. He brings in knowledge on economics of power markets and experience from environmental policy consulting.

Assessing the feasibility of Roadmpas

In our new study, we checked the feasibility of the Roadmaps for the Swiss electricity system up to 2050 from the company Helion Energy AG, the Swiss industry association Swissolar and National Councilor Jürg Grossen. have each developed roadmaps.

New project report! Check out our insights on V2G in Switzerland.

Vehicle-to-grid (V2G) – the bidirectional interaction between electric vehicles and the grid – is one way of leveraging the battery capacity to provide flexibility for the electricity system. In a new study, we make a first estimate of the potential impact of V2G on the Swiss electricity system.

Brand new Nexus-e scenarios available and in the ETH Zukunftsblog

The scenario results based on the recently finished CH2040 project, a collaboration with Prof. Patt's group for climate policy, are now available online. You can find the final project report, a link to the visualized scenario results, and Prof. Patt's contribution to the ETH Zukunftsblog on our CH2040 project page

New report on nuclear power in Switzerland

Assessing the role of the existing and new nuclear power plants for the Swiss electricity system

In this report we assess four scenarios:

The reference scenario represents the status quo of Swiss nuclear power plant (NPP) lifetime, meaning 60 years for Beznau I and II, and 50 years for Goesgen and Leibstadt.
In the NPP60 scenario, we assume that the NPPs Goesgen and Leibstadt get the approval to operate also for 60 years.
In the NPP6580 scenario, Beznau I and II operate for 65 and Leibstadt and Goesgen for 80 years.
In the NPP60+ scenario, we assume that on top of 60 years operating time for all existing NPPs also a new NPP is being constructed in 2040.

Scenario Results

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.
