Calculateur de CO2
Hourly CO2 data of the Swiss electricity mix
Issue / Challenge
High-temporal resolution of the CO2 embedded in consumed electricity is needed to assess the environmental impacts of new electricity usages, such as Heat-Pumps or Battery Electric Vehicles. Such is particularly important for Switzerland, which is highly dependent on electricity imports from neighboring countries, especially in winter, some of which heavily rely on electricity generation from fossil fuels.
Solution
Development of annual hourly datasets regarding the Swiss electricity mix, considering imports and exports:
· Analysis of high-temporal electricity generation data of Switzerland and European countries
· Identification of imports, considering trade mechanisms (merit-order principle)
· Generation of hourly data sets regarding CO2 emissions factor and renewable energy fraction
A detailed explanation of the underlying method is provided in the publication below.
Data
The analysis of the hourly Swiss electricity mix has been carried out over 8 years (2017 – 2024). The following data set corresponds to the hourly average over these years.
When using the data, please refer to the publication below.
Funding
Innosuisse (Renowave project) and University of Geneva (UNIGE)
