Electricity, approximately 80% was produced from renewable sources

by | 8 Sep 2023 | Environment

Approximately 79 percent of the electricity consumed in Switzerland in 2022 was produced from renewable energy sources (2021: 80 percent): 65 percent from hydropower (not benefiting from promotional measures) and just under 14 percent. percent from photovoltaic, wind and biomass plants as well as small hydroelectric power plants, which corresponds to an increase of two percentage points compared to 2021.

 

The data concerning the electricity mix distributed in Switzerland by electricity suppliers (see box) is collected every year and published in the “Electricity labelling” cockpit on the website www.electricity-labelling.ch. The data published today refers to 2022.

Since 2018, the obligation to fully declare the origin of the electricity supplied has been in place for electricity labelling.

This means that from supply year 2021, so-called “grey electricity”, i.e. electricity of unknown origin, is no longer permitted. Since most neighboring countries do not provide guarantees of origin (GO) for electricity produced by conventional power plants, Switzerland has introduced so-called replacement guarantees.

Electricity produced abroad from coal, for example, can thus be declared as such and no longer has to be indicated as “grey electricity”. The percentage of electricity produced from coal and imported through such replacement guarantees is consistently less than one percent.

  • 65 percent of the electricity supplied in 2022 came from large hydroelectric plants and small hydroelectric plants not benefiting from the electricity injection remuneration system (slightly less than the previous year, 2021: 68%). 68 percent of the hydroelectricity supplied was produced in Switzerland (2021: 76%). 2022 was a very dry year resulting in less indigenous hydroelectricity generation. and from small hydroelectric plants that do not benefit from the remuneration system for feeding into the grid.
  • 19.6 percent (2021: 18.5%) of the electricity came from nuclear power plants, which is less than the proportion of nuclear energy contained in the Swiss generation mix (36.4%). As in the previous year, the nuclear energy supplied was produced almost exclusively in Switzerland.
  • The percentage of new renewable energy sources (solar, wind, biomass and small hydroelectric power plants benefiting from the electricity injection remuneration system) increased further, from 11.2 (2021) to 13.7 percent in 2022. Of this percentage, approximately 68 percent is produced in Switzerland and 45 percent has benefited from the electricity injection remuneration system.
  • Only a small part of the electricity supplied in 2022 came from fossil energy sources (1.9%, unchanged compared to the previous year).

Production mix and mix distributed by suppliers do not coincide

In Switzerland, 52.8 percent of electricity is produced from hydropower, 36.4 from nuclear energy, 1.4 percent from fossil sources and 9.4 percent from new renewable energies (= mix of Swiss production 2022). Further information on this can be found in the Swiss Electricity Statistics (see link).

However, end consumers are not only supplied with electricity produced in Switzerland; our country, in fact, maintains intense commercial exchanges with foreign countries, within which it exports and imports energy.

Trade in Swiss guarantees of origin takes place within Switzerland; foreign guarantees of origin can be imported. For this reason, the Swiss generation mix does not coincide with the average composition of the electricity supplied (= mix distributed by Swiss suppliers).

To achieve greater transparency regarding the mix distributed by each supplier, thus allowing consumers to consciously choose a specific product, since 2005 Swiss electricity companies have been required by law to declare the origin and composition of the electricity they supply. The declaration is based on data from the previous calendar year.

Since 2006, these data must be made known to all consumers through their bills and since 2013 they have also been published on the Internet platform www.labelling-electricity.ch.
