Conor is currently a MSc student in Integrated Building Systems at ETH Zurich. He will conduct his Master’s thesis on coupling the two energy system modeling platforms: City Energy Analyst and Nexus-e.
With the decarbonization and decentralization of energy production, Switzerland faces two mammoth tasks in the coming years and decades. The restructuring of the energy supply requires political and investment decisions. The stakeholders in the energy sector act based on scenarios that show possible developments. Scientists at ETH Zurich have now created the modeling platform Nexus-e. It enables to create scenarios for the electricity sector and, in particular, also includes economic and grid-related issues.
The Nexus-e team has successfully completed the pilot project “The role of flexibility providers in shaping the future energy system” supported by the Swiss Federal Office of Energy. The established platform will serve as a modeling infrastructure to facilitate the analysis of future energy systems.
Nexus-e is mentioned in the GLOBE magazine as a tool helping researchers to understand the future energy system and get ready for the cleantech race.
Computational models can provide technical analysis to objectively evaluate the impact of energy policies. But why are they rarely used in public policymaking? Unclear quality of the input, non-transparent methodology, lack of validation, neglecting behavioural irrationality, and oversimplification are some of the barriers. Nexus-e makes a first step to tackle these challenges.
Negative emission technologies will likely play a critical role in reaching the goal of net-zero carbon emissions. In this project, we will analyze the technical and environmental feasibility of carbon removal with Bio-Energy with Carbon Capture and Storage (BECCS), based on the availability of biomass, bioenergy potential, and of the infrastructure for CO2 capture and sequestration.
Congratulations to Elena Raycheva for having successfully presented the methodology and results of the CentIv module at the MEDPOWER 2020 conference!
As part of the development of the Nexus-e platform, this first study sponsored by the Swiss Federal Office of Energy implements the Nexus-e core modules to research the role of flexibility providers in shaping the future Swiss electricity system.
The stability and reliability of the energy system are of critical importance for all aspects of modern life. These issues encompass the electrical infrastructure, but also other energy carriers like gas, heat and water. For the planning, operation and economic evaluation of the Swiss multi-energy system, Nexus-e provides a detailed representation of the Swiss transmission system as a basis for the bulk multi-energy grid model.
We analyze the feasibility of the Swiss decarbonization by combining the detailed representation of the Swiss electricity market of Nexus-e with the pan-European, energy sector–wide perspective of Calliope, an energy system model developed by the Climate Policy group at ETH Zurich. The collaboration with Calliope will provide Nexus-e with new scenarios of electricity demand and energy system cost. Calliope in turn profits from Nexus-e’s feedback about what its assumptions about generation capacities mean for electricity markets and for the Swiss transmission grid.
