Energy Balance 2023: Decreased electricity consumption and increased production

In 2023, Switzerland will have consumed less electricity and produced more. According to estimates from the Federal Office for Energy (BFE), electricity consumption fell by 1.7%, or about 1 terawatt-hour, compared to 2022. At the same time, domestic electricity production rose by a staggering 13.5%, or about 8.5 terawatt-hours. .

These figures are based on final statistical data for the period from January to October 2023. For November and December, the bank is still relying on preliminary estimates.

Total final electricity consumption – that is, the state's consumption minus network losses – was estimated at 56.1 terawatt-hours in 2023. The decline in consumption was particularly noticeable in the months of January, February and September. Electricity consumption was already significantly low in September 2022.

Warm temperatures in the winter months may have contributed to lower electricity consumption. Despite everything, the federal government was unable to achieve its 10% savings target.

On the other hand, household electricity generation rose to an estimated 72.1 TWh. This corresponds to an increase of about 8.5 TWh. Or, as mentioned above, a significant increase of more than a tenth compared to the previous year (63.5 TWh).

The main factor in increasing production was the increased production of hydroelectric power plants. In 2023, this electricity generated one-fifth more than in the corresponding quarters of the previous year. The four Swiss nuclear power plants produced about 1% more electricity than the previous year. Thermal and renewable energy systems were able to increase their production by about 15 percent.

Of the total electricity production, just over half came from hydropower plants. Nuclear power plants were responsible for about a third, and thermal and renewable systems for another 11%.

In 2023, Switzerland recorded an export surplus of about 6.4 TWh. Last year, Switzerland had to import about 3.4 terawatt-hours, the BFE wrote in its online magazine “energeiaplus”.
