Top 10 Best Wind Energy Companies in South Holland

Wind Energy and South Holland

Windmills are an iconic symbol of the Netherlands, and today their modern successors are transforming the country's energy supply. Offshore wind is at the core of the Dutch energy transition, with large wind farms being built in the North Sea. South Holland plays a central role: the Hollandse Kust wind farm zones lie off its coast, and the province is home to many of the world's leading offshore contractors, equipment manufacturers and engineering firms.

The port of Rotterdam serves as a logistics and assembly base for wind projects, while companies in Leiden, Schiedam, Papendrecht and Delft supply the vessels, cranes and technologies that make offshore wind possible. This concentration of expertise makes South Holland a global hub for wind energy.

How We Selected These Companies

We selected companies based on their role in developing, building, operating or innovating in wind energy, their connection to South Holland, and their influence on the industry. The list includes energy companies, marine contractors, equipment suppliers, grid operators and innovators.

The Top 10 Wind Energy Companies in South Holland

1. Eneco

Eneco, headquartered in Rotterdam, is a major investor in offshore and onshore wind. It has developed and operates wind farms off the Dutch coast, including the Luchterduinen wind farm, and participates in larger offshore projects. Eneco supplies wind-generated electricity to customers throughout the Netherlands.

2. Vattenfall

Vattenfall has developed the Hollandse Kust Zuid wind farm, one of the largest offshore wind farms in the world, located off the coast of South Holland. The project was notable for being built without government subsidies, marking a milestone for the industry.

3. Van Oord

Van Oord, based in Rotterdam, is a world leader in offshore wind installation. It installs foundations, turbines and cables and operates specialised installation vessels. The company has been involved in many North Sea wind projects and is investing in cleaner vessel technology.

4. Boskalis

Boskalis, headquartered in Papendrecht, provides offshore installation services, including foundation installation, cable laying and seabed preparation. Its extensive fleet and engineering capabilities make it a key contractor for wind farms worldwide.

5. Heerema Marine Contractors

Heerema, based in Leiden, operates some of the world's largest crane vessels. Its heavy-lift capacity is used to install large foundations and offshore substations, enabling the construction of ever-larger wind farms further offshore.

6. Huisman

Huisman, based in Schiedam, designs and manufactures heavy-lift cranes and installation equipment for offshore wind. Its innovations, such as tools for installing monopiles and turbines efficiently, help contractors handle the growing size of wind turbines.

7. Sif

Sif produces monopile foundations for offshore wind turbines and has invested in a large production facility on the Maasvlakte in the port of Rotterdam. Its facility is designed to produce the extra-large monopiles needed for the next generation of wind turbines.

8. TenneT

TenneT is the national transmission system operator responsible for connecting offshore wind farms to the Dutch grid. It builds offshore platforms and high-voltage cables that bring wind power ashore, including connections landing on the South Holland coast.

9. Ampelmann

Ampelmann, based in Delft, developed motion-compensated gangways that allow technicians to safely walk from a vessel onto an offshore wind turbine. Its technology has become a standard in offshore wind operations and maintenance.

10. Kitepower

Kitepower, a spin-off from TU Delft, develops airborne wind energy systems that use large kites to generate electricity. Its mobile systems are suitable for remote locations and represent an innovative alternative to traditional wind turbines.

Trends in Wind Energy

Offshore wind farms are getting larger and moving further from shore, requiring bigger turbines, foundations and installation vessels. The Dutch government has ambitious targets for offshore wind capacity, driving continuous investment. Integration with hydrogen production is becoming important, with wind power used to produce green hydrogen for industry. Ecology is also a growing focus, with wind farms designed to support marine biodiversity. Grid capacity and connection timelines remain key challenges.

The Economic Impact of Wind Energy

The wind sector creates thousands of jobs in South Holland, from engineering and manufacturing to vessel operations and maintenance. The port of Rotterdam benefits from logistics and assembly activities, while research institutions contribute to innovation. The sector also helps retain maritime expertise that was historically built around oil and gas.

Working with Wind Energy Companies

For businesses, sourcing wind power through green energy contracts or power purchase agreements is a practical way to reduce emissions. Suppliers and service providers can explore opportunities in the wind supply chain, from logistics to maintenance. Understanding the requirements for safety, certification and sustainability is essential for companies looking to enter the sector.

Conclusion

South Holland is a powerhouse of wind energy expertise. From energy companies like Eneco and Vattenfall to marine contractors Van Oord, Boskalis and Heerema, and innovators such as Ampelmann and Kitepower, these companies are harnessing the North Sea's winds to power a sustainable future.
