Applications of the Nexus-e platform
Electricity generated from rooftop photovoltaics systems have the largest renewable potential in Switzerland and are expected to contribute substantially to the future Swiss electricity mix. However, so far, these systems are behind their expectations, which is why an update of PV policies is discussed. In this project, we investigate an alternative to the prevailing support scheme. What we call the “customer-oriented feed-in tariff” remunerates solar electricity injected to the grid with a percentage of the retail electricity price, the price electricity customers are paying for electricity consumption.
The Swiss Federal Office of Energy (SFOE) launched the funding programme SWEET in 2020 to boost innovative approaches towards implementing Switzerland’s Energy Strategy 2050. Nexus-s will on of the three models leveraged in SWEET EDGE – Enabling Decentralized renewable GEneration in the Swiss cities, midlands, and the Alps – to develop scenarios for the Swiss energy transition.
SWEET PATHFNDR: PATHways to an Efficient Future Energy System through Flexibility aND SectoR Coupling
The Swiss Federal Office of Energy (SFOE) launched the funding programme SWEET in 2020 to boost innovative approaches towards implementing Switzerland’s Energy Strategy 2050. Nexus-e is the central tool for one of the four selected consortia “PATHFNDR”. PATHFNDR focuses on improving renewable energy system efficiency through flexibility and sector coupling. 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. In this project, Nexus-e will be extended to represent the entire Swiss energy system.
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.
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.
