Frequently asked questions

Hollandse Kust Zuid Wind Farm

  • Why is the Hollandse Kust Zuid Wind Farm being built?

    In the coming years, the Dutch government wants to dramatically reduce the emission of greenhouse gases (such as CO2). For this reason, they have entered into a number of agreements. The Energy Agreement (2013), the Paris Climate Agreement (2015) and the National Climate Agreement (2019). The government decides where the wind turbines will be located and the Dutch Enterprise Agency issues the tender, and in this way the decision is made about who will build the wind farm.

  • How can Vattenfall build the wind farm without a subsidy?

    In the past, a government subsidy was needed in order to build a wind farm out at sea. The cost price of offshore wind energy has dropped appreciably in the last few years. The way in which the government now looks for a location, makes preparations, issues ready-to-roll licences and guarantees the connection to the national grid, carries a lot less risk nowadays. This, in turn, means lower costs. This means that Vattenfall will be able to build HKZ without any financial support from the government.

  • How much experience does Vattenfall have of building wind farms?

    Vattenfall, the Swedish parent company of Nuon, is one of the largest players in generating wind energy. We have built and manage 71 wind farms in Europe. Of these, 51 are land-based and 20 are offshore. Thanks to our many years of experience, we are now able to provide the maximum amount of green electricity from our wind farms in a safe and reliable way.

  • How big is the wind farm?

    The total area of the Hollandse Kust Zuid is made up of four sections that are also called parcels. Vattenfall is building parcels 1-4. Parcel 1 consists of 67 km2, parcel 2 consists of 48 km2, parcel 3 consists 46 km2 and parcel 4 consists 64 km2. The wind farm will eventually provide approximately 1.500 megawatts (MW) of power

  • Where will Hollandse Kust Zuid Wind Farm be sited?

    Vattenfall will build the wind farm in the North Sea, at least 18 kilometres from the coast, in the area between The Hague and Zandvoort. In some cases, it will be even further out to sea. Thus, the distance of the wind farm from the coast of The Hague will be 23.5 kilometres.

  • Why is the wind farm being built in this area of the North Sea?

    In order to counter climate change, the Dutch government has decided that a great many wind farms need to be built. Vattenfall as a company does not make the decision about the location of the wind farm, the Dutch government does. The location of Hollandse Kust Zuid in the North Sea is favourable. The quality of the seabed is good and it is not too deep. The wind farm is easily accessible from the port of IJmuiden.

  • How many wind turbines will there be in the wind farm?

    At present, the number of wind turbines in the wind farm is not certain. We expects to place around 38 wind turbines on each of the four parcels, which add up to around 150 wind turbines in total. Vattenfall has selected Siemens Gamesa for delivering the turbines.

  • How tall are the wind turbines?

    The permit prescribes a maximum height of 251 metres. Vattenfall is currently investigating what the most optimal height is. The wind turbines that Siemens Gamesa will deliver, have a rotor diameter of 193 metres.

  • What type of wind turbines will be installed at the wind farm?

    Vattenfall and Siemens Gamesa are joining forces to deploy the newest 10 MW (SG 10.0-193 DD) turbine in the North Sea.

  • How much green energy will the wind farm produce?

    By mid-2023, the wind farm will be generating clean energy for 2 to 3 million households. That is enough to provide green energy for nearly all of the province of South Holland. The wind farm will eventually provide approximately 1.500 megawatts (MW) of power.

  • What is the power output of the wind farm?

    This is the maximum output of a wind farm that Vattenfall can make use of in normal conditions. The production capacity of the Hollandse Kust Zuid Wind Farm depends on the number and type of wind turbines that are installed. This wind farm will produce a maximum of 1.500 MW.

  • When will construction of the wind farm begin?

    If everything goes according to plan, Vattenfall’s suppliers will commence production of the necessary hardware for the wind farm in 2021. The equipment includes the parts for the wind turbines, foundations for the wind turbines and the power cables. Vattenfall will start constructing the wind farm out in the North Sea in 2022.

  • Who will be building the Hollandse Kust Zuid Wind Farm?

    Nuon commenced operating the first wind farm in the North Sea in 2006. This was the Egmond aan Zee Wind Farm. Less than twelve years later, Vattenfall, the parent company of Nuon, will build the first wind farm without a government subsidy. This is the Hollandse Kust Zuid Wind Farm. By 2025, Vattenfall is aiming to generate 7,000 megawatts from wind power in Europe. To achieve this, we are investing heavily in wind energy.

  • Can the wind farm be seen from the coast?

    Whether or not you can see the wind farm depends on a number of factors. These factors include the weather conditions, the time of day and the season. In clear weather conditions, the Hollandse Kust Zuid Wind Farm can be seen from the coast.

  • What is the operating life of the wind farm?

    The Hollandse Kust Zuid Wind Farm will operate for 25-30 years. In order to ensure that the wind farm operates for the longest possible time, we will be carrying out regular maintenance. When the wind farm needs to be dismantled in the future, we will comply with all the regulations and measures that are laid down in the licence.

Employment opportunities

  • How many new jobs will be created by the construction of the wind farm?

    The construction of the wind farm will create more employment opportunities. In 2017, approximately 2,000 people were employed in offshore wind power in the Netherlands. Researchers predict that this number will have grown to 12,000 jobs by 2021. Precisely how many new jobs will be created in the construction of the Hollandse Kust Zuid Wind Farm is still not known.

  • In what way will local companies along the coast benefit from the construction of this wind farm?

    Employment opportunities in the region will benefit from the construction of the wind farm. In 2017, approximately 2,000 people were employed in offshore wind power in the Netherlands. Researchers predict that this number will have grown to 12,000 jobs by 2021. Precisely how many new jobs will be created in the construction of the Hollandse Kust Zuid Wind Farm is still not known.
