Our Task

The energy transition is the biggest challenge facing the Netherlands. In the future, we want to fundamentally change our energy supply. We are on the way to a sustainable energy supply. This means that we no longer want to use fossil fuels in the future and are therefore relying on renewable energy sources. Wind energy, generated at sea (=offshore), is an essential building block for this.

In the Climate Agreement it was agreed to make the Dutch energy supply more sustainable. This will reduce CO2 emissions and combat climate change. Energy generated at sea plays an important role in this. To get the green energy on land, an electricity connection is needed from an offshore wind farm to the land.

Offshore transmission system operator

TenneT is the offshore transmission system operator. This means that TenneT ensures that offshore wind farms are connected to the onshore electricity grid via the offshore grid, so that the generated energy can be used. The construction of the offshore grid contributes to TenneT's ambition to be a driving force behind the energy transition.

About these projects

TenneT Nederland has been the grid operator at sea since 2016. The offshore grid transports generated wind energy from the sea to the onshore electricity grid. This takes place from wind energy areas in the North Sea. The government has designated these areas to generate renewable energy. We connect wind farms to our national high-voltage grid via standard connections of 700 megawatts (MW) of alternating current and 2,000 megawatts (2 GW) of direct current for wind farms located further offshore.

Ambitious goal

As a cross-border grid operator we are making an important contribution to achieving the European Green Deal

The share of renewable energy in the energy mix must increase to 80 percent by 2030. To achieve this ambitious goal, the Dutch government has decided that some 21 gigawatts (GW) of offshore wind energy must be connected to the high-voltage grid by 2030. This is equivalent to three quarters of the current total electricity consumption in the Netherlands.

In the European Green Deal, the European Union has set itself the ambition of realising around 300 gigawatts (GW) of offshore generation capacity in Europe by 2050. As a cross-border grid operator, we are making a significant contribution to this. In Germany and the Netherlands, we have realised more than 8.5 GW (status January 2022) of connection capacity for offshore wind energy. No other grid operator in the European Union has yet connected so many wind farms to the electricity grid.

Our technology

Standardisation of grid connections

In order to meet the ambitious energy targets, the expansion of the offshore grid must be accelerated. TenneT has developed technical solutions and new concepts based on many years of experience.

In the Netherlands, TenneT will complete seven standard alternating current (AC) connections, each with a capacity of 700 MW, by 2026. From 2028, wind farms further offshore will be connected to 2,000 MW (= 2 GW) of standard direct current connections. Because of the large capacity (2 GW per connection) and in order to limit the loss of power during transmission, TenneT will implement this connection as a direct current (DC) connection. Standardisation of these grid connections will substantially reduce the costs of development, construction and maintenance.

2 GW

In the '2GW Programme', a new and innovative offshore standard has been developed in close cooperation with various partners from the market. One fits all: a new standardised platform, a new certified cable system, a higher transmission capacity: all with as little impact on the environment as possible. The 2GW Programme forms the basis for our next-generation offshore grid connection systems.

Our challenges

The future

The government wants to achieve its climate targets even faster. In order to achieve the desired acceleration in the roll-out of offshore grid, TenneT sees great potential in a meshed grid. At present, offshore wind farms are so-called point-to-point connections. They are, in fact, green power plants with a cable connection to land. In a meshed grid, certain grid connections at sea are connected to each other.

WindConnector/Multi-purpose interconnector

TenneT - on behalf of the Minister of Economic Affairs & Climate Change - is investigating the possibility of making more efficient use of the grid infrastructure for the Dutch wind area IJmuiden Ver by connecting it to the United Kingdom via a WindConnector, also known as a Multi-purpose interconnector.

Offshore NL 2019 WindConnector

Like a conventional interconnector, a WindConnector enables cross-border electricity transmission and trade. The difference, however, is that this cross-border functionality is combined with the infrastructure that connects offshore wind farms to the national electricity grid. More information can be found on the website of the Dutch government and in this report (both Dutch only).
