The offshore wind farm Empire Wind, off the northern East Coast of the USA, is scheduled to go into operation in 2026. Connection technology from Germany is being used in the turbines and on the offshore platform.

Empire Wind 1 and 2 have a total capacity of more than two gigawatts and are expected to generate enough wind power to supply more than a million New York households with renewable energy. Empire 1 is scheduled to go into operation in 2026.

Pfisterer is a leading technology company for insulating and connecting electrical conductors. Connection technology from the German company is used in the wind turbines of Empire Wind 1 by Vestas: the 236-15.0 MW series is among the most powerful currently available. Each of the turbines is connected with Pfisterer fittings specifically developed for offshore applications. Pfisterer's plug-in connection system offers the possibility to test the entire array cable infrastructure before turbine installation. The connection work is carried out quickly and easily based on the plug-and-play principle. This accelerates project execution, saves time and costs, and provides a permanently reliable connection.

Custom-tailored junction box for turbine towers

"Our turbine towers are transported in segments to the installation site in the wind farm. To keep the offshore assembly time as short as possible, Pfisterer has developed a customized junction box for Vestas. This allows the pre-assembled cables in the tower segments to be connected easily and quickly by plugging them together. It's somewhat like plugging in an extension cord at home, just on a larger scale," explains Stephan Kremers, project manager at Vestas.

For the wiring of the offshore platform, the choice also fell on technology from Pfisterer, including Seanex. Pfisterer's universal connection systems have been tested in the offshore sector for over 25 years and are installed in numerous wind farms worldwide.

First order for Pfisterer’s new plant in North America

During the installation work, so-called "dropper cables" are used. These prefabricated cables with plugs enable a quick and efficient electrical connection between the switchgear (GIS) and the joint to the submarine cable at the base of the turbine. The assembly of the dropper cables took place at the new Pfisterer plant in Rochester, New York. Rochester is the newest site in the global plant network and supplies the American continent with Pfisterer technology. Additionally, installers in Rochester are trained in the installation of Pfisterer cable fittings. "Our products are used in many large offshore wind farms, but Empire Wind 1 is a special project for us. It's the first order in which our new plant in Rochester is directly involved," says Marcus Horn, President of Pfisterer North America.

In extreme offshore conditions, reliable connection technology is crucial. This interface competence makes us a reliable partner for planners, engineers, and operators of offshore wind farms.

Connection technology for the high seas

Member of the Executive Board of Pfisterer Holding SE, Dr. Konstantin Kurfiss: "Our mission is to actively help shape the transition to a sustainable world. Power generation in offshore wind farms plays a key role in achieving global CO₂ targets." "Under extreme conditions on the high seas, reliable connection technology is crucial. This interface competence makes us a reliable partner for planners, designers, and operators of offshore wind farms," adds Dana Felberg, Team Lead Renewables Projects at Pfisterer.

Among renewable energies, wind power is considered to have great growth potential; its share of the energy balance will continue to rise. (Image:EBM-Papst with Adobe Firefly (AI-supported))
