Electricity market

The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.

The Dutch high-voltage grid is connected through interconnectors with Germany, Belgium, Great Britain and Norway. The charts below give insight into the import and export (transport) of electricity with these countries.

Key Figures

Explanation on the charts

Total import and export

This chart shows the total realized and planned imports and exports between the Netherlands and countries connected to the Netherlands. The figures for the planned imports and exports are based on the commercial value of the electricity. The quantities of electricity actually transported via the interconnectors, reflect the realized imports and exports. These two values differ as electricity is not only imported to and exported from the Netherlands, but electricity is also transported via the Netherlands. As electricity chooses the route of lowest resistance, electricity for example generated in northern Germany may be transported via the Netherlands to southern Germany.  This means no import or export has taken place even though electricity has been transported across national borders.

Import/export from and to NL

This chart shows the current imports from and exports to each country from and to the Netherlands in the previous hour.

To view country-specific data, click on the relevant country (use the Ctrl key to select multiple countries) in the charts ‘Current import per country’ and ‘Current export per country’.

Actual import/export per country

Electricity can be simultaneously imported from and exported to some countries because there is more than one electricity interconnector (connection) with that country. This chart displays the total imports and exports via these interconnectors with Germany (GE), Belgium (BE), Great Britain (GB) and Norway (NO) per hour.
