Switching to renewable energy requires strong electrical systems, careful engineering, and good teamwork across different fields. As offshore wind farms get bigger and more complex, providing safe, reliable, and standard-compliant solutions is more important than ever.
Hornsea 1 Offshore Wind Farm is a major milestone in renewable energy. Built by Ørsted in the North Sea, it was the first offshore wind farm in the world to go over 1 GW of capacity. With 1.2 GW and 174 turbines, it provides clean electricity to over one million UK homes and helps the country reach its Net Zero goals.
VSS Power provides engineering, design, and project support throughout the project. By using technical know-how, following international standards, and working closely with all stakeholders, VSS Power helped build a strong electrical system for one of the world’s biggest offshore renewable energy projects.
