Winter electricity balance

The figure shows Switzerland’s cumulative electricity import or export balance for the current winter period, from October to March. A red value indicates net imports, meaning that Switzerland imported more electricity overall than it exported. A green value indicates net exports, meaning that Switzerland exported more electricity overall than it imported.

 Show explanation about the chart
Electricity production and electricity consumption in the winter months (October - March) over the last 5 years are shown. The difference is shown as green exports (or export surplus) in the case of a production surplus and as red imports (or import surplus) in the case of a production deficit. The consumption is the national consumption including the consumption of the storage pumps.
The heating degree days serve as an indicator for the heat demand and result from the sum of the daily deviations of the average outdoor temperature from a room temperature of 20°C, whereby heating is required to maintain this room temperature on days with an outdoor temperature of 12°C or less.

Presentation of total production in the winter months (October - March) over the last 5 years. Production is broken down by technology.

For the visualisation of winter electricity production, winter electricity consumption, imports and exports, the monitoring data from Swissgrid are used instead of the electricity statistics of the SFOE. The reason for this is the near-real-time availability of the data from Swissgrid. It should be noted that these monitoring data are based on modelling and schedule data and that the values differ from the electricity statistics.


The data situation regarding measurements of Swiss production is not satisfactory. While measurement data in hourly resolution are available for medium and large power plants, such data are not available for the smaller plants or only feed-in to the grid instead of production. Thus, models have to be used which take into account meteorological data such as temperature, solar radiation and precipitation. In addition, the historical behaviour of the electricity generation categories is used. The production shown in the daily resolution includes both measured and modelled data. Due to the data situation and the modelling, there may be deviations from the electricity statistics of the federal government.
