Cross-border load flows

Net Transfer Capacity (NTC) and commercial load flows at the Swiss borders

Swissgrid regularly updates the data on this page to indicate how much power flows across Switzerland’s borders and how much cross-border capacity is utilised. The charts illustrate the available transfer capacities and the commercial load flows actually used at the borders with Austria, Italy, France and Germany. Swissgrid also indicates whether Switzerland was importing or exporting electricity overall. The data shows how Switzerland is integrated into the European energy market and how the existing grid capacities are utilised.

The data is published weekly as soon as all the figures for the previous week are available. Consequently, the complete previous week is always shown. A CSV file with the annual data is also available for download at the bottom of the page.

Transfer capacities, market schedules and price differences

The charts show the commercial load flows (known as «market schedules») between Switzerland and neighbouring countries. The commercial load flows result from trading activities. They represent the market-based direction and level of energy exchange and should be distinguished from the physical load flows via cross-border lines. The charts show positive figures for net exports to the neighbouring area, and negative figures for net imports. They correspond to the intraday market schedules.

The Net Transfer Capacity (NTC) represents the limits for the market schedules across the respective borders set by the transmission system operators for security reasons. They correspond to the intraday NTCs.

The right-hand scale shows the price difference on the spot day-ahead market between Switzerland and the relevant neighbouring country (in EUR/MWh). It shows the extent to which the day-ahead market prices differ.

The combination of these three variables shows how commercial load flows are often linked to price differences:

Net load flows across all Swiss borders

This chart shows the total commercial load flows across all Swiss borders. Consequently, the figures indicate whether Switzerland is a net importer or net exporter of electrical energy overall.
