Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Grid capacity map

What opportunities are there for new feed-in initiatives on the TenneT grid in the Netherlands? The map below provides immediate insight into where and how much capacity is available at the connection stations.

On our journey to a sustainable energy supply, society has seen a rapid development of solar and wind power. All these initiatives have led to many requests on the network for a connection in recent years.

As a result, the maximum available transmission capacity for the redelivery of electricity has been reached in a number of places. TenneT's online map makes it transparent which high-voltage substations have transmission capacity available for feed-in electricity.

If a station is coloured green, there is room for a connection and the requested transmission can be facilitated. If a station is coloured red, there is no transmission capacity available at that moment. It is also possible that research into the possibilities of congestion management is ongoing. In that case the station is coloured blue.   

These insights help initiators of sustainable production and regional grid operators to gain immediate insight into the available capacity on the high-voltage grid. The map is updated every quarter. Changes may occur at that time, for example because additional capacity is available due to expansion of the infrastructure or because new requests mean that a station has reached its maximum capacity.
